Discover the best angle for solar panels in the UK and optimise energy production with the ideal roof angle for maximum sunlight absorption and efficiency.

<p>As we navigate the path to a sustainable future, harnessing the sun's clean, renewable power through <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> has become increasingly important. The UK isn't exactly known for its abundant sunshine, so why has solar power gained significant momentum here in recent years?</p>
<p>This little island we call home has a remarkable solar energy generation capacity. Contrary to popular belief, solar panels don't need Sahara-level heat to operate at full capacity. Too much heat can actually reduce their efficiency. All they need is sunlight, indirect or direct. But, to make every ray of sunshine count, you must install your solar panels at precisely the right angle.</p>
<p>In this guide, we'll walk you through the best angle for <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> in the UK and why getting the right install angle is essential to maximising your solar PV system, no matter what roof angle your home has.&nbsp;</p>
<h2>Why is the angle of your solar panels important?</h2>
<h3>1. Maximising energy production</h3>
<p>Tilting your solar panels at the right angle enables them to capture more sunlight throughout the day and the year. The increased exposure allows the panels to convert more sunlight into electricity, resulting in higher energy production and greater savings on your electricity bills.</p>
<p>The optimal angle for solar panels in the UK is facing south, at an angle between 20&deg; and 50&deg;. The best angle is worked out based on your location's latitude, which means the ideal positioning of your solar panels differs depending on where you are in the world.</p>
<h3>2. Avoiding areas of shade</h3>
<p>The angle of your solar panels can help avoid the areas and impact of shade on your property. When panels are tilted, they're less likely to be affected by shade from nearby objects, such as trees, buildings or chimneys. By minimising shadows, the panels absorb as much sunlight as possible, producing more energy for your home.</p>
<h3>3. Getting the greatest return on your solar panel installation</h3>
<p>Setting the panels at the recommended angle for UK homes allows you to capture more sunlight throughout the day and year, resulting in higher energy production.</p>
<p>The more electricity produced, the more significant the <a href="https://www.boxt.co.uk/solar/guides/energy-saving-solar-panels" rel="follow">savings on your electricity bills</a> will be. This will lead to you breaking even on your solar investment sooner.</p>
<h3>4. Generating electricity throughout the year, not just in the summer months</h3>
<p>The Earth's tilt changes throughout the year, according to which season we're in, which affects how the sun's light hits us. By adjusting the tilt angle of your solar panels, you can account for these variations and optimise their performance accordingly.</p>
<p>Installing panels at a fixed angle might capture less sunlight during winter when the sun is lower, meaning you won't get as much energy for your home.</p>
<h2>The best angle for solar panels on a flat roof</h2>
<p>The optimum angle for solar panels on flat roofs is around 30 to 35&deg;. This angle helps the panels balance, maximising solar energy production and allowing rain to flow off them easily.</p>
<p>The angle considers the UK's geographical location and attempts to capture direct sunlight all year round, accounting for the lower angle of the sun during winter months.&nbsp;</p>
<h2>The best angle for solar panels on a pitched roof</h2>
<p>The ideal angle for solar panels on pitched roofs ranges from 30 to 40&deg;. This recommended solar panel orientation means you're making the most of energy production during summer and winter. A professional solar installer can provide a more precise recommendation based on your property.</p>
<h2>The best direction for solar panels in the UK</h2>
<p>If you have a fully south-facing roof, you're in luck. In the UK, the sun's path mainly goes from the south-east to the south-west. South-facing solar panels capture sunlight when it's most intense, meaning you'll get the most out of your solar panel system.</p>
<p>If you have a fully north-facing roof, you might face some issues when it comes to solar output. They're generally not recommended in the UK, as they receive significantly less sunlight and lower energy production than south-facing installations.</p>
<p>To overcome this issue, you can install your solar panels using a mounting system pitched against the slope of your roof. It may not be the most aesthetically pleasing setup, but it will dramatically affect your energy bills.</p>
<h2>Key considerations for installing solar panels</h2>
<ul>
<li>What direction does your roof face?</li>
<li>How much sunlight does your property get?</li>
<li>Are there any objects that could cast a shadow on your solar panels?</li>
</ul>
<h2>What about if you can't install solar panels on your roof?</h2>
<p>If you can&rsquo;t have solar panels installed on your roof, don't worry. Although it's common to see solar panels on roofs, they can also be installed in gardens and on walls, as we&rsquo;ll explore below.</p>
<h3>The best angle for solar panels in gardens</h3>
<p>When it comes to <a href="https://www.boxt.co.uk/solar/" rel="follow">solar installation</a> in your garden, the best angle and orientation are very similar to rooftop installation - ranging from about 30 to 40&deg;.</p>
<p>Since solar panels in gardens are often ground-mounted, they can be adjusted to different tilt angles easily. This flexibility allows you to optimise the angle based on the season or sun exposure in your garden.</p>
<h3>Tips for installing solar panels on a wall</h3>
<p>If your roof isn't suitable for solar panel installation, you can mount them on an external wall. Although they can be trickier to install, you'll find they're much easier to maintain and clean than roof panels. Debris and snow can't build up on them in the same way.</p>
<p>Here are some tips to get the most out of your wall-mounted solar panels:</p>
<ul>
<li>Choose a south-facing wall with minimal shade.</li>
<li>Make sure the wall is structurally sound and capable of supporting the weight of the solar panels.</li>
<li>Use a reliable and robust mounting system specifically designed for wall installations (a professional installer will be able to select the correct mounting brackets, rails and attachment methods suitable for your wall type and local weather conditions).</li>
<li>Plan the wiring and inverter placement carefully to ensure efficient energy transfer from the panels to the electrical system.</li>
<li>Keep wiring concealed and protected from the elements.</li>
</ul>

What is the best angle for positioning solar panels in the UK?

Learn about how wind turbines and solar panels compare as renewable energy sources. Find out which one is right for your home and household’s energy usage.

<p>Whether it&rsquo;s for financial or environmental reasons (or a combination of both), we&rsquo;re all looking for ways to become more energy-efficient at home. And now, as the UK continues along the road to net zero emissions, this has only grown more important.</p>
<p>Investing in renewable energy sources is one of the ways that we, both as a nation and as individuals, can contribute positively to global efforts to reverse the effects of climate change.</p>
<p>But this is complicated stuff, so it&rsquo;s natural that many of us find it tricky to get to grips with the ins and outs of which method of energy production is right for us. Should we go solar? Or is our lifestyle better suited to wind turbines?</p>
<p>Here, we break things down into simple, straightforward terms, exploring the features, benefits and key considerations of <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> and wind turbines.</p>
<h2>Renewable vs non-renewable: what's the difference?</h2>
<p>First things first, let's get to grips with renewable and non-renewable energy as concepts.</p>
<p>Oil, coal and natural gas - collectively known as fossil fuels - are non-renewable energy sources. Whilst scientists do technically know how to make these fuel sources, the process takes billions of years, so it's not practical for us to do so within our lifetimes.</p>
<p>This means that once our fossil fuel reserves are gone, they're gone.</p>
<p>Scientists reckon that global supplies of fossil fuels will last until around 2060. But, if we want to limit global warming to within the 1.5&deg;C target set at COP26, we'll need to leave at least 80% of these supplies untapped.</p>
<p>Energy sources like solar and wind power are renewable. Being renewable means that they come from natural sources that we can replenish at a faster rate than we use. This makes things like solar, wind, geothermal, biomass and tidal energy sustainable in the long term.</p>
<p>Renewable energy sources are also clean energy sources, meaning they don't generate harmful greenhouse gas emissions during production or distribution - good for our health and that of the planet!</p>
<h2>What are wind turbines, and how do they work?</h2>
<p>Think of wind turbines as being the modern version of windmills. As the wind blows, large propellor-like blades capture the gusts and turn around a rotor. This rotor is connected to a generator, which converts kinetic energy into usable electrical energy.</p>
<p>When we talk about wind turbines, most of us will picture the huge, towering structures we see sitting in open spaces or off UK coastlines. When there are lots of wind turbines together in one location, they become wind farms.</p>
<p>You can also get smaller wind turbines designed for individual or residential use. Whilst these can't generate power at the same scale, they still use wind energy to produce electricity.</p>
<h2>What are solar panels, and how do they work?</h2>
<p>Solar panels (also known as photovoltaic panels or PV panels) are devices made from a variety of materials, largely silicon, that collect and convert sunlight into energy that can be used to power your home.</p>
<p>The material that solar panels are made from is known as semi-conductor material; for that reason, it has the capability to collect heat from the sun's rays and turn them into an energy source.</p>
<p>For a more detailed run-down, take a look at our guide on how solar panels work.</p>
<h2>Wind turbines vs solar panels: cost</h2>
<p>While investing in renewable energy may feel like a big expenditure at the time, you&rsquo;ll likely see the return on your investment in 5 to 10 years after installation. What&rsquo;s more, with the inclusion of renewable energy, you&rsquo;ll see the value of your home or business soar in years to come.</p>
<p>Luckily, the surge in the popularity of solar panels has had a positive effect on prices, gradually bringing them down over the last decade. That said, the cost of <a href="https://www.boxt.co.uk/solar/" rel="follow">solar installation</a> is completely subjective to a number of factors, such as the size of the system required, the energy demands of the household, and the type of panels.</p>
<p>So, if you're all about saving those pennies while going green, solar power seems like the clear winner when it comes to cost. If you&rsquo;re serious about <a href="https://www.boxt.co.uk/solar" rel="follow">solar panel installation</a> and want to speak with an expert to discuss your options, get in touch with a member of the team at BOXT.&nbsp;</p>
<h3>Upfront cost</h3>
<p>When it comes to solar panel expenses, a lot depends on how many you're installing, what type of solar panel you're fitting, and who instals the system.&nbsp;<br>One of the most common sizes in 2024 for a household in the UK is a 4kW solar panel system. The 4kW solar panel system costs between &pound;6,000 and &pound;7,000, requires around 10 - 16 panels and covers approximately 29 square metres of your roof. Note this is for the system alone and does not factor in the installation costs.</p>
<p>That said, installing a wind turbine system can see you spending anywhere from &pound;9,000 to a whopping &pound;30,000 - depending on the type you require and how much energy you plan to harness from them.</p>
<p>Meanwhile, when installing a wind turbine, you've got two options: the pole-mounted and the building-mounted variety. When comparing the two, the clue is in the name. Pole-mounted turbines are typically the taller of the two, located and installed in fields or areas of land.</p>
<p>Whereas building or roof-mounted turbines are smaller, more compact counterparts that are fitted on a rooftop. Building-mounted turbines are more affordable than pole-mounted turbines, but they provide significantly less electricity and have a much shorter lifespan.</p>
<p>And let's not forget that the energy capacity of each turbine also plays a role in the overall expenditure. A 2.5kW system will cost you anywhere from &pound;9,000 to &pound;19,000, while a more robust 6kW system will set you back around &pound;21,000 to &pound;30,000.</p>
<h3>Maintenance cost</h3>
<p>Like any advanced machinery, wind turbines and solar panels do require some TLC to keep them spinning smoothly and absorbing sunlight efficiently.</p>
<p>According to Wind Measurement International, the maintenance cost of a wind turbine system could be anywhere between 1.5 and 2% of the original investment per annum. You&rsquo;ll want to make sure they are regularly maintained due to the fact that moving parts will encounter more wear and tear over time than static parts.</p>
<p>Luckily, solar panels are well-known for being low-maintenance. However, it is worth putting aside some savings just in case your solar panels encounter any issues that might see them becoming ineffective - such as micro-cracks or a family of pigeons making a home underneath them.&nbsp;</p>
<h2>Wind turbines vs solar panels: efficiency</h2>
<p>Wind turbine efficiency is determined by the availability and strength of the wind in its desired location. Similarly, the amount of sunlight received in a given location influences the effectiveness of solar panels. Wind and solar resources can vary greatly from one area to the next, affecting their total measured efficiency.</p>
<p>To further divulge the subject of efficiency, let's look at some variable factors.</p>
<ol>
<li><strong>Land use: </strong>Wind turbines generally require more land area than solar panels to generate electricity. Making solar panels a more accessible and efficient choice for homeowners who may not have the landmass to fit wind turbines.</li>
<li><strong>Capacity factor: </strong>This measures the actual output of a renewable energy source (wind turbine or solar panel) compared to its maximum potential output. Wind turbines typically have a higher capacity factor than solar panels because wind energy is more consistent and less affected by daily weather changes than solar energy, which relies on how much UV light it can absorb.</li>
<li><strong>Energy storage: </strong>Wind and solar energy are intermittent, which means their generation depends on weather conditions. Energy storage systems, like batteries, are critical for maximising both technologies' performance and assuring a constant power supply.</li>
</ol>
<p>Roughly, wind turbines harness their energy more than solar panels. It is estimated that wind turbines harness 60% of the energy that passes through them, compared to the 18 to 22% efficiency of solar panels. Of course, this relies on a number of aforementioned variables.&nbsp;</p>
<h2>Wind turbines vs solar panels: installation</h2>
<p>For pole-mounted turbines, the installation involves erecting a tall tower with turbine components on top, whereas solar panels and building-mounted turbines require mounting on various structures like rooftops or racks.</p>
<p>Specifically, wind turbine installation involves:</p>
<ul>
<li>Site selection</li>
<li>Foundation</li>
<li>Tower erection</li>
<li>Turbine installation</li>
<li>Electrical connection</li>
</ul>
<p>For solar panels, installation involves:</p>
<ul>
<li>Site selection</li>
<li>Mounting structure</li>
<li>Panel installation</li>
<li>Wiring and inverters</li>
<li>Grid connection</li>
</ul>
<p>Each technology's appropriateness is determined by factors such as wind resources, sunshine exposure, available space, and local legislation. However, both make important contributions to renewable energy generation and can be combined to produce an efficient alternative to running the home.</p>
<h2>Wind turbines vs solar panels: reliability</h2>
<p>If you're looking to install a renewable energy source for your home, then you'll already know they're a big monetary investment. So, it's important to know roughly how long they are going to last and how long you can expect to save money on your energy bills.</p>
<p>Because solar panels don&rsquo;t need direct sunlight to collect energy, they are effective even in a climate as unpredictable as Britain. That&rsquo;s why so many households are considering and have already switched to this renewable source of energy. Whether used in a hybrid set-up or entirely off-grid, solar panels can be a cheaper alternative (in the long run) for providing electricity to your home.</p>
<p>What&rsquo;s more, they are easy to install, require little space and little maintenance. However, due to all the complicated technologies involved in the manufacturing of solar panels, they are much harder to recycle.</p>
<p>Building-mounted wind turbines require a similar amount of space to solar panels. However, wind turbines need to be placed in an environment where they&rsquo;ll receive a lot of wind to operate effectively.</p>
<p>So if you live in a valley or an area with low wind, such as a city centre, then you&rsquo;ll likely not notice many turbine farms or residential wind turbines. However, if you reside on the coast or in the Highlands, then you&rsquo;ll probably be somewhat accustomed to wind turbines.</p>
<p>Turbines are a great investment if you have the environment to harness their usage. But for a typical homeowner, they might not be the most reliable source of energy as they are typically hard to install, require more space and come with a higher maintenance bill.&nbsp;</p>
<h2>Wind turbines vs solar panels: environmental impact</h2>
<p>Typically, whilst wind turbines are a good investment on a global scale and their manufacturing process is a lot less detrimental to the planet, they might not be the most environmentally savvy choice for homeowners.</p>
<p>There&rsquo;s no getting away from the fact that the manufacture of solar panels takes large quantities of materials and a significant amount of energy. That said, they are a great option for homeowners when compared to wind turbines, as they are compact, easy to install, affordable and can provide energy even when faced with a cloudy climate.</p>
<h2>Wind turbines vs solar panels: pros and cons</h2>
<p>So, what&rsquo;s the upshot of all this? When it comes to deciding what renewable energy source or sources are right for your home, think about your usage habits (present and future) along with your budget and available space for installation.</p>
<p>To help you compare options, here&rsquo;s a rundown of the main benefits and limitations of wind turbines and solar panels.</p>

Wind turbines vs solar panels: which is better?

Explore whether solar panels can power a house without using back-up from a solar battery and how you can sell excess energy to the national grid.

<p>Installing solar panels is an excellent way to reduce your carbon footprint and energy costs, but it's essential you do your due diligence before committing to solar electricity.</p>
<p>One of your main queries will likely be about how much solar energy your home will be able to generate. After all, you want to ensure your renewable energy investment will pay dividends.</p>
<p>Here, we explore the electricity generation properties of <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> to help you understand whether you can power your home without using battery storage to save more energy. And, if you don't intend to invest in a solar battery, we explain how you can sell excess electricity back to the national grid.</p>
<h2>How much power do solar panels generate?</h2>
<p>According to Ofgem, the average 3-bedroom British home uses 2,900 kilowatt-hours (kWh) of electricity annually or around 242 kWh per month.</p>
<p>If you had 10 3.5kW solar panels, these would typically create around 2,645kWh of electricity or around 90% of the electricity you use yearly. However, this does not mean your monthly energy bills will reduce by 90% because we don't get consistent sunlight all day, every day in the UK. It's also why so many people invest in solar batteries, to maximise the use of their solar panel systems and conserve solar power to use later.</p>
<p>What factors affect how much power your panels produce?</p>
<p>The amount of electricity solar panels produce is largely dependent on several factors, including:</p>
<h3>1. Shading</h3>
<p>If trees or other buildings partially or fully shade your solar panels, their performance and how much solar power they can generate will be affected.</p>
<h3>2. Sunlight intensity</h3>
<p>As well as having a good amount of sunlight, the sun's intensity will impact energy consumption too. Panels that receive a higher intensity of sunlight will generate more solar power.</p>
<h3>3. Panel orientation and tilt</h3>
<p>During the day, the sun goes from east to west, meaning south-facing solar panels are exposed to the most sunlight. If you install solar panels facing the north, they will be exposed to less sunlight and produce less solar power.</p>
<h3>4. Temperature</h3>
<p>While good levels of sunlight intensity are beneficial to solar panels, higher temperatures can actually decrease the efficiency of solar panels.</p>
<h3>5. Cleanliness of solar panels</h3>
<p>Keeping your solar panel system clean and free of dirt and debris is crucial to ensuring an efficient system. Allowing dirt, such as bird droppings, to collect on your solar panels will block sunlight and reduce energy production.</p>
<h3>6. The quality of your solar system</h3>
<p>While opting for a cheaper solar PV system might save you money on your initial investment, a lower-quality system could cost you more in the long run. The overall quality of your solar panel system and its components, like inverters and mounting systems, can impact energy production and the system's longevity.</p>
<h2>Can solar panels power a house without battery storage?</h2>
<p>In short, without a battery, you could generate 100% of your home&rsquo;s electricity as long as the weather is in your favour; however, if conditions are not ideal and you cannot store energy, you may be forced to use and pay for electricity from the national grid.&nbsp;<br>Whether or not solar panels can power your home without battery storage will depend on several factors, including the number of solar panels you have installed and your home&rsquo;s demand for energy.</p>
<p>Solar panels could power your home on a good day with 100% electricity. However, due to the varying weather conditions in the UK and the inability to store solar power, you may have to rely on your electricity provider the next day.&nbsp;</p>
<h2>How to get the most out of your solar panels</h2>
<p>To maximise your solar power costs and the energy efficiency of your system, you should take the following steps.</p>
<h3>1. Ensure optimal placement and tilt</h3>
<p>Even if you don't have a south-facing roof, you can still have solar panels installed in your home. Solar installers will consider how to maximise sun exposure within the manufacturer&rsquo;s recommended limits. Some solar panel frames even have hinges so you can tilt them towards the sun.</p>
<p>Alternatively, solar panels could be installed in your garden too, so there are plenty of ways to optimise the placement of your system.</p>
<h3>2. Minimise shading</h3>
<p>If you notice trees or hedges overshadowing your solar panels, you must cut them back to maximise the performance of your panels.</p>
<h3>3. Undertake regular maintenance</h3>
<p>Keeping your solar panels clean from dirt and debris and regularly inspecting them will maintain their efficiency and longevity.</p>
<h3>4. Invest in a solar battery</h3>
<p>Solar battery storage is essential to maximise the electricity your solar panels generate. Naturally, your solar panels won't create as much energy at night as they do during the day, so if you store extra power, you can reduce your dependency on the national grid.&nbsp;</p>
<p>Read everything you need to know about solar batteries in our complete <a href="https://www.boxt.co.uk/solar/guides/what-is-a-solar-panel-battery" rel="follow">guide to solar battery storage</a>.</p>
<h3>5. Monitor performance</h3>
<p>Once you have installed solar panels at your home, monitor their performance regularly and keep an eye on the amount of energy they are generating. This will help you identify any problems with your solar panel system before they get too serious.</p>
<h3>6. Analyse your energy consumption</h3>
<p>As well as monitoring the performance of your solar panels, you should also look at how much energy your household currently uses. By doing this, you can identify power-hungry appliances and change how you use them, to save money and live more efficiently.</p>
<h3>7. Research Government incentives</h3>
<p>To stick to low-emissions targets, the Government offers a series of grants to encourage people to switch to solar energy. These financial incentives include money to help you buy solar panel systems and more.&nbsp;</p>

Explore the full range of Government grants available to you in our Solar panel grants in the UK blog.

<h2>Selling excess solar energy to the national grid</h2>
<p>Under the Smart Export Guarantee, you can sell excess units of electricity back to the national grid. To start selling electricity back to the grid, you'll have to register with one of the utility companies that offer this service, but once you're signed up, you can earn around 10p per kWh generated. The amount you can earn will depend on several factors, including:</p>
<ul>
<li>The amount and size of the solar panels you have</li>
<li>Your current household energy usage</li>
<li>The amount of power you generate</li>
<li>The energy supplier you register with</li>
</ul>
<h2>More solar suggestions from BOXT</h2>
<p>In summary, although you can generate a large portion of your home's electricity usage with solar panels, without a battery, it may not be possible to power 100% of your home. Despite this, solar is an excellent investment and renewable energy source that will reduce your energy bills in a big way, and you can even make money by selling excess energy back to the national grid.</p>

Can solar panels power a house without a back-up?

If you live in the UK, you’re no stranger to pigeons. But having pigeons nesting under your solar panels is not ideal. Find out how to control them here.

<p>Over the years, many homeowners have noticed an increase in pigeons nesting on their roofs between their <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a>. And, whilst it doesn't significantly impact the operation of your solar panels, pigeons are notorious for spreading disease, releasing nasty pathogens into the atmosphere and making a racket wherever they roost.</p>
<p>With this in mind, for the health of your household and the performance of your solar panels, it&rsquo;s best to take steps to avoid pigeons nesting under your solar panels.<br>In this guide, we&rsquo;ll walk you through what to do to ensure that you and your family are the only ones benefiting from your solar energy.</p>
<h2>How do pigeons impact your solar panels?</h2>
<p>Unlike most birds, pigeons need cover over their heads when nesting, and they nest all year round in the UK. Unfortunately, the gap between solar panels and the roof is like a dream come true for birds, especially pigeons.</p>
<p>As well as making a mess and potentially spreading disease, pigeons may affect your solar panels in these four ways:&nbsp;</p>
<h3>1. Damage caused by corrosion</h3>
<p>Pigeon droppings contain substances that can harm solar panel surfaces. Continuous exposure may cause the panel&rsquo;s protective coating to deteriorate - reducing how well the panels absorb sunlight.&nbsp;</p>
<p>Additionally, pigeons' sharp claws can damage or scratch the surface of the panels, further decreasing their effectiveness.</p>
<h3>2. Electrical components at risk</h3>
<p>As pigeons navigate your solar panel system, their actions and motions can damage wiring connections, resulting in short circuits or even total electrical failure. This may lead to a decrease in power output or, in certain situations, the inability of the panels.</p>
<h3>3. Nesting and debris on and between the panels</h3>
<p>While your solar panels will provide cover from the elements, pigeons will make nests from twigs to keep themselves warm. The material and debris from nest-making will accumulate quickly, obstructing your panels, reducing ventilation, and affecting their performance.</p>
<p>This buildup may impact your solar panels' performance and efficiency over time.</p>
<h3>4. Requires regular cleaning and maintenance</h3>
<p>Whilst solar panels are known as a low-maintenance source of renewable energy, if you have a pigeon problem, you'll likely be cleaning them more often. You must clean pigeon droppings regularly to avoid damage and maintain a solar panel's optimal performance. Moreover, the accumulation of pigeon fouling on the panels, gutters, and surrounding areas can obstruct sunlight absorption and be a potential health hazard.&nbsp;</p>
<p>Regular solar panel services can ensure early detection of pigeons nesting and reduce the risk of pigeon problems persisting.&nbsp;</p>
<p>To better understand how to maintain and prevent any solar-related problems, look at our guide on <a href="https://www.boxt.co.uk/solar/guides/how-do-solar-panels-work" rel="follow">how solar panels work</a> to help you prevent any avoidable situations. By taking good care of your solar panel system in the first instance, you'll see them perform optimally, reducing your energy bills.</p>

<h2>How does pigeon-proofing solar panels work?</h2>
<p>Pigeon-proofing solar panels involves building a barrier between the panels and the roof. To achieve this, install a border around the perimeter of the solar panels to prevent pigeons from gaining access.</p>
<p>Unfortunately, once pigeons have made a home on your roof, getting rid of them can be hard work. So preparing for this before <a href="https://www.boxt.co.uk/solar/" rel="follow">solar installation</a> is a much wiser, proactive move than trying to fix a current infestation. If you do find pigeons nesting in amongst your solar panels, we recommend speaking to expert installers or engineers to see how they can help rather than attempting to tackle the problem yourself.</p>
<p>Here are the general steps to prevent pigeons from nesting on your solar panels:</p>
<ol>
<li><strong>Install bird mesh to curb a pigeon infestation:</strong> You can stop pigeons from nesting underneath solar panels by installing chicken wire or bird mesh around the outer edge of your solar panels. Remember, installing bird mesh can be challenging and should only be attempted by someone with prior bird eradication knowledge.</li>
<li><strong>Fit bird netting around the panels: </strong>Another worthy method of preventing pigeons from nesting is fitting netting around the panels. Bird netting prevents them from entering their desired area and setting up shop.</li>
<li><strong>Anti-roosting spikes:</strong> These are a viable option for people looking to deter pigeons. However, recent studies have shown that some species of birds have found ways, and somewhat evolved, to use the anti-roosting spikes to build their nests. Over time, these may not be the most viable option for those looking to stop pigeons' nesting.</li>
<li><strong>Keeping your garden clean:</strong> What might seem like a simple solution, ensuring your garden is kept clean, is a surefire way to keep unwanted pests at bay. This is because you are mitigating their opportunity to find substances and food waste to feed on. Keeping your bins tightly sealed and any rubbish cleared away can prevent pigeons from being attracted to your home.</li>
</ol>
<h2>How much does it cost to pigeon-proof solar panels?</h2>
<p>The cost of pigeon-proofing solar panels varies according to the size and type of panels protected. A mesh or netting system typically costs between &pound;50-&pound;100 per metre. As a result, pigeon-proofing an average-sized solar panel of 2 square metres will cost between &pound;300 and &pound;600.</p>
<p>For further clarity, look at our guide on the <a href="https://www.boxt.co.uk/solar/guides/types-of-solar-panels" rel="follow">types of solar panels</a> to get a better estimate of the size of pigeon-proofing you may need to undertake.</p>
<p><img src="https://cdn.buttercms.com/xwGPh2mbRcO9EzCPz8cQ" alt="pigeon on a solar panelled roof"></p>
<h2>Do I need to pigeon-proof my solar panels?</h2>
<p>It is entirely up to you, the homeowner, if you want to pigeon-proof your solar panels. With most things, it is easier to prevent the problem before it arises, and because pigeons nest all year round, it&rsquo;s best to do it during installation or immediately after. Allowing the problem to build up will only make it more difficult to eradicate in the future. You can get quotes from local pigeon-proofing services to arrange this.</p>
<h2>Is pigeon-proofing solar panels essential?</h2>
<p>Removing pigeons from solar panels has seen a huge surge in the past decade. As the problem arises, homeowners, landlords and building managers have experienced sleepless nights trying to rectify the situation. Gone are the days of pigeons nesting in your chimney, as solar panels are a much cosier alternative with more effective protection.</p>
<p>As mentioned above, the impact pigeons have on a solar operating system is only slight if the problem persists for a long period. However, by keeping on top of the maintenance and not allowing them to nest, you'll get more out of your solar panels and continue to save on your energy bills.</p>
<p>So whilst it may not feel like an essential part of the <a href="https://www.boxt.co.uk/solar" rel="follow">solar installation</a>, preventing pigeons from accessing the space beneath the panels will help reduce these concerns and ensure your solar energy system performs well.</p>

Pigeon-proofing solar panels - Is it necessary?

Explore how long different types of solar panels last, which factors affect their lifespan, and the measures you can take to extend the life of your solar panels.

<p>Investing in <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> is an excellent way of reducing your carbon footprint and your electricity bills. It can typically take 10-15 years to see a return on your investment, but how long do solar panels last?</p>
<p>As with all technologies, over time, solar panels degrade, so before you switch to this renewable energy source, it&rsquo;s good to know how you can maximise their use and your money. Here, we explore how long solar panels last and what you can do to extend your solar panel&rsquo;s lifespan.</p>
<p>But first, let&rsquo;s take a quick look at how a solar power system actually works.&nbsp;</p>
<h2>How do solar panels work?</h2>
<p>Regardless of the type of solar panels you have, they all work in the same way, as simplified below:</p>
<ol>
<li>Sunlight hits the solar panels</li>
<li>Photons of light are transferred into the panels</li>
<li>The light frees the electrons that sit in the panels from their atomic bonds</li>
<li>The solar cells then collect these electrons to generate an electrical current</li>
<li>This electricity is collected in direct current (DC) form before being converted into alternating current (AC) by an inverter</li>
</ol>
<p><img src="https://cdn.buttercms.com/oxOkrXSERH0ODFfPMvGS" alt="Graphic cross-section of a house with solar panels on the roof which are used to power appliances" width="897" height="682"></p>
<h2>What factors affect how long solar panels last?</h2>
<p>There are several factors that can influence how long solar panels last. These include:&nbsp;</p>
<h3>1. The quality of the materials used</h3>
<p>The old saying of &lsquo;if you buy cheap, you buy twice&rsquo;, applies to solar panels. If you buy high-quality solar panels made with durable materials and components, they will be much more likely to last longer than their cheaper equivalents. That&rsquo;s why, before you commit to buying a solar panel system, you should do your research on solar panel manufacturers.&nbsp;</p>
<h3>2. How well the panels are maintained</h3>
<p>Ensuring your solar panels are kept clean and well-maintained will help to prolong their life. A fully qualified technician should inspect the panels annually, and you should keep the panels clear of debris and dirt to prevent damage and optimise performance. &nbsp;</p>
<h3>3. Quality of the solar installation</h3>
<p>Poor installation practices can have a negative impact on solar panel efficiency and how long they last. Proper <a href="https://www.boxt.co.uk/solar" rel="follow">solar installation</a> by trained solar panel installers will help mitigate the risk of problems like structural issues, water leaks, and more.&nbsp;</p>
<h3>4. The rate of degradation</h3>
<p>Over time, solar panels will decrease in effectiveness; this is known as panel degradation. On average, solar panels degrade at a rate of between 0.5 and 1.0% every year. So, a typical solar panel&rsquo;s performance will drop off by around 12-15% over its 25-30 year lifespan. &nbsp;</p>
<h3>5. Environmental factors</h3>
<p>Solar panel life expectancy will be affected by weathering, particularly extreme weather like heat waves and heavy snow or hail. While this is unavoidable, exposure to harsh weather will affect how long solar panels last.&nbsp;</p>

Let's face it: the UK isn't the first country that comes to mind when we think of sunshine. But are they still a viable means of generating electricity? Learn how solar panels generate electricity during the winter and the factors that can impact their efficiency.

<h2>How to extend the lifespan of your solar panel system</h2>
<p>To ensure a good return on your investment, adhere to solar panel warranties, and extend the lifespan of your home solar panel system, you should aim to keep on top of the following things.</p>
<h3>Clean your solar panels regularly&nbsp;</h3>
<p>Keeping your solar panels clean and free of debris, like bird droppings, will help to improve their performance and help your solar panels last longer. When it comes to <a href="https://www.boxt.co.uk/solar/guides/how-to-clean-your-solar-panels" rel="follow">cleaning your solar panels</a>, always follow the manufacturer&rsquo;s advice to avoid damaging the panels.&nbsp;</p>
<h3>Organise inspections with a professional solar panel installer&nbsp;</h3>
<p>Having your solar system inspected by a trained professional enables them to spot any issues, like loose wiring or corrosion. As well as spotting issues, an inspection ensures peace of mind about the overall condition of your solar panels.&nbsp;</p>
<h3>Monitor performance</h3>
<p>Tracking the performance of your solar panels will help you keep an eye on the degradation rate of your system, and if there&rsquo;s a significant drop, it could indicate that there&rsquo;s an issue.&nbsp;</p>
<p>Like with <a href="https://www.boxt.co.uk/boilers" rel="follow">boilers</a> and other household appliances, a large number of issues can be repaired relatively easily, provided they're addressed promptly and not allowed to escalate. If you're concerned about the performance of your home's boiler, hybrid heat pump or solar panel system, it's always best to contact a qualified engineer to investigate as soon as possible.</p>
<h3>Manage shading and obstructions</h3>
<p>Where you can, you should take steps to ensure that buildings and trees do not cast a shadow over your solar panels. Shading can reduce the panels&rsquo; efficiency, so keep an eye on any trees or shrubs and ensure they&rsquo;re pruned and trimmed regularly.&nbsp;</p>
<h3>Adhere to the manufacturer&rsquo;s guidelines&nbsp;</h3>
<p>When you have your solar panels installed, you&rsquo;ll receive various pieces of information, including instructions from the manufacturer. Following the recommendations in these guidelines can maximise the lifespan of your solar panels and preserve the warranty of your panel system.&nbsp;</p>
<h3>Implement control measures to manage weather</h3>
<p>Extreme weather events, while rare, can impact your solar panels&rsquo; expected lifespan and ability to produce electricity. In the UK, we rarely experience tornados, but protecting your solar panels against snowfall and hailstones by investing in weather guards can extend their lifespan.</p>
<h2>The lifespan of different solar panel types</h2>
<p>The three main types of solar panels used on residential and commercial properties in the UK are monocrystalline, polycrystalline and thin-film panels. Each of these solar panels is made in different ways and will, as a result, have varying lifespans.</p>
<p>Check out our blog for more information on&nbsp;<a href="https://www.boxt.co.uk/solar/guides/types-of-solar-panels" rel="follow">the different types of solar panels</a>, <a href="https://www.boxt.co.uk/solar/guides/how-efficient-are-solar-panels" rel="follow">solar panel efficiency levels</a> and <a href="https://www.boxt.co.uk/solar/guides/uk-solar-panel-prices" rel="follow">the price of solar panels</a> in the UK.</p>
<h3>Monocrystalline solar panels</h3>
<p>Monocrystalline solar panels are made from a single silicon crystal. While the manufacturing process is complex and the panels more expensive, they do offer high levels of efficiency and can last up to 40 years.&nbsp;</p>
<h3>Polycrystalline solar panels</h3>
<p>Polycrystalline solar panels are made up of multiple crystals of silicon in a photovoltaic cell. Often incorporating fragments of silicon leftover from producing monocrystalline solar panels, polycrystalline solar panels are a cheaper alternative that can last up to 35 years.&nbsp;</p>
<h3>Thin-film solar panels</h3>
<p>Made from other materials, like copper indium gallium selenide (CIGS) or cadmium telluride, thin-film solar cells are around 350 times slimmer than crystalline silicon solar cells. While their thinner, lighter composition makes thin-film solar cells much easier to install, they do degrade at a faster rate, with a typical lifespan of between 10 and 20 years.</p>
<h2>Key takeaways</h2>
<p>The lifespan of your solar panels will vary depending on a number of factors, like their exposure to weather, if they&rsquo;re shaded by trees or buildings, and more.</p>
<p>To ensure your solar panels have a long life, you should ensure that they are regularly monitored and seek professional assistance when it comes to making any repairs and conducting inspections.</p>
<p>With a good amount of care and attention, monocrystalline panels can last up to 40 years, while polycrystalline models can last up to 35 years, and thin-film solar panels can have a lifespan of around 20 years.</p>

How long do solar panels last?

Thinking of installing solar panels on your property? Get all the information you need in this guide on the advantages and disadvantages of solar energy.

<p>Solar power has grown increasingly popular over the past decade, holding onto its spot as the UK's third-largest source of renewable energy.</p>
<p>And with good reason, too. As a nation, we&rsquo;re all on a journey towards achieving net zero emissions by 2050, and cleaner, greener energy sources will play a huge part in getting us there.</p>
<p>Thanks to investments in developing solar technologies, <a href="https://www.boxt.co.uk/solar">solar panel</a> systems are now widely available for domestic and commercial use. But, if you&rsquo;re considering switching from more traditional, fossil fuel-based energy sources, you&rsquo;ll want to know whether it&rsquo;s the right move for you.</p>
<p>In this guide, we cut through the noise and explain the main advantages and disadvantages of solar energy so you can make an informed decision about what&rsquo;s best for your home or business.&nbsp;</p>
<p>Want answers at a glance? Don't worry; we've got it covered. Here's an infographic showing the main benefits and limitations of solar.</p>
<p><img src="https://cdn.buttercms.com/ysUKkZgFSxODdGmLozYO" alt="Infographic summarising the benefits and limitations of solar energy, covering the environmental and cost-saving pros and the upfront investment and reliability cons."></p>
<h2>The advantages of solar energy</h2>
<p>There are many advantages to harnessing solar energy beyond the obvious environmental benefits we read and hear about so often in the news. Here is a list of the main ways in which solar power can prove beneficial to us in practice.&nbsp;</p>
<h3>Solar is a renewable energy source</h3>
<p>Fossil fuels are non-renewable energy sources, meaning that once our reserves are gone, they&rsquo;re gone! The likes of coal, oil and natural gas take millions (yes, millions) of years to form, so we won&rsquo;t be able to replenish our supplies within our lifetimes.</p>
<p>This simple fact makes fossil fuels an unsustainable way of powering our homes, businesses and cars long term.</p>
<p>By contrast, solar power is a renewable source of energy. The sun isn&rsquo;t going to stop shining any time soon, meaning we can continue generating electricity using solar panels indefinitely.</p>
<p>As the world transitions away from non-renewable to renewable energy, sources like solar, wind, hydro and geothermal power will become mission-critical to ensure we&rsquo;re able to carry on living our lives as normal.&nbsp;</p>
<h3>Solar is more environmentally friendly than fossil fuels</h3>
<p>There&rsquo;s no getting away from the fact that protecting the environment is at the top of pretty much every government&rsquo;s priority list.</p>
<p>As global warming and the impacts of climate change run riot on nations worldwide, politicians and activists are putting ever-increasing emphasis on the need for us all to take decisive steps before it&rsquo;s too late.</p>
<p>Using cleaner energy sources such as solar plays a part in making this possible. Producing and using solar energy doesn&rsquo;t generate nearly as many greenhouse gas emissions as fossil fuels, which, in turn, helps us to reduce our carbon footprints and contribute less to air pollution.</p>
<p>Explore more <a href="https://www.boxt.co.uk/green-homes/guides/best-green-ways-to-heat-your-home" rel="follow">green ways to heat your home</a> on our blog.</p>
<h3>Solar panels provide homes with independent energy</h3>
<p>Solar panels can be installed on rooftops in urban, suburban and remote rural areas, enabling off-grid energy production. This makes solar panel systems an excellent option for people who want or need to become less reliant on centralised power grids and fossil fuel imports.</p>
<h3>Solar panel systems reduce energy costs from other sources</h3>
<p>Unlike oil and gas companies, the sun doesn&rsquo;t charge us for the energy it provides. This means that once we have accounted for the upfront cost of installing solar panels, the electrical energy they generate is free!</p>
<p>In the long term, relying on solar power rather than fossil fuels can help reduce our energy bills and protect us from wholesale oil and gas price fluctuations.</p>
<h3>Solar panels can increase the value of your property</h3>
<p>Beyond the immediate cost-saving benefits of generating your own electricity, solar energy can also increase the value of your home. Our research found that, on average, installing solar panels can increase the value of a property by an incredible 14%, which equates to an additional &pound;29,300 in Manchester and &pound;90,000 in London.&nbsp;</p>
<p>Read more about how switching to solar could save or even earn you money in our <a href="https://www.boxt.co.uk/news/guides/boxt-energy-report" rel="follow">Energy Report</a>.</p>
<h3>Solar is a long-term investment</h3>
<p>As the cost of solar technology decreases and electricity prices rise over time, the return on investment improves. Solar panels can increase property value and be a great source of electricity for years to come, making them a worthwhile long-term investment.</p>

<h2>Disadvantages of solar energy</h2>
<p>Of course, it can't all be sunshine and rainbows (pun intended). Solar power systems are a welcomed and integral part of modern energy solutions, but they are not without drawbacks. Here is a list of the main drawbacks of using solar energy to power your home.&nbsp;</p>
<h3>Solar energy supplies can be inconsistent&nbsp;</h3>
<p>Since solar energy relies on sunlight, its availability largely depends on weather conditions and time of day. On days with thick cloud cover, at nighttime, and in areas with limited sunlight, you can expect to see a reduction in the amount of energy your panels produce.</p>
<p>Depending on location, this infrequency may mean your system requires solar energy storage systems or backup power sources to ensure the electricity supply remains consistent.</p>
<p>As a compromise, you could consider a <a href="https://www.boxt.co.uk/boilers/guides/what-is-hybrid-heating" rel="follow">hybrid heating system</a> which uses a renewable power source, such as solar panels of a heat pump, and a traditional source, such as a gas <a href="https://www.boxt.co.uk/boilers" rel="follow">boiler</a>. In a hybrid system, the two work together to provide a balance between environmentally friendly and reliable home heating.</p>
<h3>Solar panels have high upfront costs</h3>
<p>Whilst <a href="https://www.boxt.co.uk/solar/guides/uk-solar-panel-prices" rel="follow">the price of solar panel systems</a> has decreased over the past decade, they still require quite a significant upfront investment.</p>
<p>You&rsquo;ll need to consider several expense factors when weighing up the pros and cons of solar panels, including the price of the panels themselves, the labour required to install them and any additional energy storage solutions.</p>
<p>So, although solar panel systems do end up paying for themselves through the money you&rsquo;ll save on your energy bills, the upfront investment may be too great for some. If parting with one lump sum feels unmanageable, there are other ways to cover the cost of installing solar panels on your home.</p>
<p>At BOXT, we offer monthly repayment plans to make going green as easy and affordable as possible (subject to status, T&amp;Cs apply). Fill in our <a href="https://www.boxt.co.uk/solar" rel="follow">easy online form</a> to get a no-obligation quote and find a payment plan that&rsquo;s right for you. &nbsp;</p>
<h3>Installing solar panels can require a lot of space</h3>
<p>Solar panels will take up a significant amount of space on your roof or other surface to generate a worthwhile amount of electricity.</p>
<p>While rooftop <a href="https://www.boxt.co.uk/solar" rel="follow">solar installations</a> are the most common way for people to power their homes, not all houses have sufficient suitable space. If you&rsquo;re tight on roof space, you could explore installing solar panels in your garden or mounting them onto the walls of your property.&nbsp;</p>
<h3>Solar panels can lose efficiency over time</h3>
<p>While <a href="https://www.boxt.co.uk/solar/guides/how-efficient-are-solar-panels" rel="follow">solar panel efficiency</a> has improved significantly in recent years, not all sunlight that reaches the panels is converted into electricity and efficiency rates also vary from model to model.&nbsp;</p>
<p>Additionally, natural factors like dust, dirt, shading, or even prolonged exposure to high temperatures can reduce panel efficiency over time if you don&rsquo;t maintain them properly.</p>
<p>To maximise the efficiency of your solar panel system, ensure that your installer mounts them to your property&rsquo;s roof at the correct angle and that they're kept clean of debris.</p>
<p>Read our expert's guide to learn <a href="https://www.boxt.co.uk/solar/guides/how-to-clean-your-solar-panels" rel="follow">how to clean your solar panels</a>.</p>
<h3>Storage solar energy can be challenging</h3>
<p>Solar energy systems produce electricity during the day, but energy demand can be highest during the evening or nighttime when everyone is home from work or school.</p>
<p>You can manage this effectively, though, with the addition of <a href="https://www.boxt.co.uk/solar/guides/what-is-a-solar-panel-battery" rel="follow">solar battery storage</a>. These cells store any excess energy generated during the day so that it's available for use during periods of low or no sunlight.</p>

The advantages and disadvantages of solar energy

What types of solar panels are best for your home? We explore the most common types of solar systems, comparing efficiency, cost,  appearance & suitability.

<p><a href="https://www.boxt.co.uk/solar" rel="follow">Solar panel</a> technologies are becoming more affordable and efficient with each year that passes, meaning increasing numbers of homeowners are considering&nbsp;<a href="https://www.boxt.co.uk/solar" rel="follow">solar panel systems</a> as a way to reduce their carbon footprints, save energy and reduce their electricity bills.</p>
<p>In fact, <a href="https://www.boxt.co.uk/solar/guides/energy-saving-solar-panels" rel="follow">our research</a> shows that if you live in a standard semi-detached house with a 10-panel system, you could save nearly &pound;900 on your electricity bills every year.</p>
<p>Before you commit to having solar panels installed, though, it&rsquo;s good to know which types of solar panels will be most suitable for your home.&nbsp;</p>
<p>So, to help you decide what&rsquo;s right for you, we&rsquo;re looking at the three main types of panels: monocrystalline, polycrystalline, and thin-film solar panels.&nbsp;</p>
<p>Here, we explore how these types of solar panels work, how efficient they are, how much they cost, what the panels look like, and evaluate the pros and cons of each.</p>
<h2>What are the different types of solar panels?&nbsp;</h2>
<p>The three main types of solar panels are monocrystalline, polycrystalline and thin-film, with each type offering different benefits. The most suitable type of solar panel for you and your home will depend on several factors, like your budget and property type.&nbsp;</p>
<p>Whatever your priority is, whether it&rsquo;s buying the most efficient solar panel or the most cost-effective, we have the answers you need below...</p>
<h2>Monocrystalline solar panels</h2>
<p>Monocrystalline solar panels can offer a good return on investment during their lifespan and are typically used by businesses due to their impressive levels of efficiency.</p>
<h3>How do monocrystalline solar panels work?&nbsp;</h3>
<p>Monocrystalline panels get their name from the single silicon crystal structure that they&rsquo;re made from. The production process involves forming a large silicon crystal, which is cut into solid silicon wafers. Although this method is more expensive, the wafers are very efficient due to their uniform structure.&nbsp;</p>
<h3>How much do monocrystalline solar panels cost?&nbsp;</h3>
<p>While the manufacturing process ensures a high-quality product, this comes at a cost. Monocrystalline solar panels are more expensive than polycrystalline and thin-film solar cells.&nbsp;</p>
<h3>How efficient are monocrystalline solar panels?&nbsp;</h3>
<p>Monocrystalline solar panels benefit from being around 20% efficient. These solar cells have a higher capacity, too, with most cells providing over 300 watts of power.&nbsp;</p>
<p>The uniform structure of monocrystalline panels means they&rsquo;re more robust than polycrystalline and thin-film panels, meaning they typically have a longer lifespan.&nbsp;</p>
<p>With this being said, because solar cells are made from a single piece of silicon, the size of monocrystalline panels is limited, and larger installations can require more panels and space as a result. &nbsp;</p>
<h3>What do monocrystalline solar panels look like?</h3>
<p>The cells of monocrystalline solar panels tend to appear black because of how sunlight reacts with the pure silicon crystal.&nbsp;</p>
<h3>The pros and cons of monocrystalline solar panels</h3>

<h2>Polycrystalline solar panels</h2>
<p>These panels are made up of multiple crystals of silicon in a single photovoltaic cell. The silicon used to form the cells can include fragments leftover from the monocrystalline manufacturing process, as well, thus minimising waste.&nbsp;</p>
<h3>How do polycrystalline solar panels work?&nbsp;</h3>
<p>Monocrystalline and polycrystalline panels work in the same way. When sunlight hits the panel, the photons of light transfer energy to the silicon panels, awakening the electrons within them and freeing them from their atomic bonds. The solar cells then collect the free electrons to generate an electrical current.&nbsp;</p>
<p>The resulting electricity is in the form of direct current (DC), which is passed through an inverter and converted into alternating current (AC) to be used in our homes.&nbsp;</p>
<h3>How much do polycrystalline solar panels cost?</h3>
<p>Polycrystalline solar cells are cheaper than their monocrystalline equivalents due to the fact they are produced from silicon fragments as opposed to one crystal. This essentially means the manufacturing process is more straightforward and cheaper, and the consumer ultimately sees the benefit, too. &nbsp;</p>
<h3>How efficient are polycrystalline solar panels?&nbsp;</h3>
<p>The relative downside to the more cost-effective manufacturing process is that polycrystalline cells are slightly less efficient - with levels at around 15-17%. Additionally, polycrystalline panels tend to have lower wattage capacities, so they produce less electricity.&nbsp;</p>
<p>The difference in wattage, however, does not mean that polycrystalline cells are smaller physically. In fact, monocrystalline and polycrystalline panels do have the same number of cells, but monocrystalline cells work more effectively.&nbsp;</p>
<p>With regards to the temperature coefficient, which measures how a solar panel performs in warm temperatures, a monocrystalline solar cell performs better. &nbsp;</p>
<h3>What do polycrystalline solar panels look like?</h3>
<p>Polycrystalline cells look more blue than monocrystalline solar cells. This is because light reflects off the silicon fragments in a different way than it does on a monocrystalline wafer.&nbsp;</p>
<h3>The pros and cons of polycrystalline solar panels</h3>

<h2>Thin-film solar panels</h2>
<p>Thin-film solar panels are usually made from copper indium gallium selenide (CIGS) and are around 350 times thinner than a crystalline solar cell. Despite this, the actual solar panel may be a similar thickness depending on the frame used.&nbsp;</p>
<h3>How do thin-film solar panels work?</h3>
<p>A thin-film panel works in the same ways as a monocrystalline or polycrystalline solar panel - absorbing the sun&rsquo;s light to free electrons from their atomic bond.&nbsp;</p>
<p>Unlike the other panels in this guide, however, thin-film solar panels can be made from different materials, including cadmium telluride, the CIGS mentioned above, and amorphous silicon.&nbsp;</p>
<h3>How much do thin-film solar panels cost?</h3>
<p>The cost of thin-film solar panels will vary based on the type of material - CIGS panels are much more expensive than cadmium telluride or amorphous silicon panels. Compared to monocrystalline and polycrystalline panels, thin-film panels can be a more cost-effective alternative.&nbsp;</p>
<p>The cost of having thin-film solar panels installed may be lower than the crystalline equivalents, too. This is due to the fact that thin-film panels are lighter and easier to carry onto roofs - making the <a href="https://www.boxt.co.uk/solar" rel="follow">solar installation</a> process faster and more straightforward. &nbsp;</p>
<h3>How efficient are thin-film solar panels?&nbsp;</h3>
<p>Thin-film panels tend to be less efficient and have lower wattage capacities than crystalline solar panels, offering efficiency levels of around 11%.&nbsp;</p>
<p>Where monocrystalline and polycrystalline panels come in standard sizes, thin-film panels don&rsquo;t. So, the ability of thin-film panels to generate electricity will largely depend on the size of the panel - the larger your panel, the more energy you&rsquo;re able to generate (in theory).</p>
<h3>What do thin-film solar panels look like?</h3>
<p>As the name suggests, a thin-film solar panel has a slimmer appearance than the two crystalline solar panels. In terms of colour, thin-film panels can be either blue or black, depending on what they&rsquo;re made from.&nbsp;</p>
<h3>The pros and cons of thin-film solar panels</h3>

There are many reasons for this. One of the biggest reasons is that they form a key part of the UK government's target to reach net zero by 2050.</p>
<p>But when it comes to a heat pump vs solar panel, which is the better choice?</p>
<p>We've put together this detailed side-by-side comparison to give you all the information you need to make an informed decision.</p>

<p>Heat pumps are incredibly efficient as they produce a larger amount of heat than the electricity they use. This is because they extract heat from the air or ground. Modern boilers can achieve <a href="https://www.boxt.co.uk/boilers/guides/boiler-efficiency" rel="follow">over 90% efficiency</a> which is impressive.</p>
<p>However, many estimates state that a ground source heat pump can be up to 400% efficient.</p>

<p>One of the main downsides of installing a heat pump is the upfront cost. According to the Energy Saving Trust, this costs between &pound;7,000 and &pound;13,000. However, until April 2025, the <a href="https://www.boxt.co.uk/boilers/guides/government-grants-for-heat-pumps" rel="follow">UK government is offering grants</a> of &pound;7,500 to cover some of the costs of installation.</p>
<p>Still, as heat pumps are a fairly new type of renewable energy system in the UK, there are other costs involved. Depending on the type of home you live in, you may need to install new radiators or underfloor heating. You may also need to improve your home's insulation and windows.</p>

<p>The upfront costs of installing solar panels vary depending on the size and type of your home. On average, it costs around &pound;5,420 to install a solar panel system in a three-bedroom house.<br>If you want to be able to use thermal energy from your solar power system at night, you'll also need to buy a battery. These cost around &pound;4,500. So, the cost of installing solar panels is significant.</p>
<p>However, there is a way to quickly recoup some of these costs. You'll only use so much thermal energy during the day which means your panels should be producing more energy than you actually use. To combat wastage, you're able to sell electricity to an energy supplier.</p>
<p>This is a particularly good idea if you haven't bought a battery for storing unused energy.</p>

Heat pumps vs. solar panels: which is best?

Here, we explore how solar panels work with your electricity bill, how they can affect your monthly energy bill, and how you make money by selling excess electricity back to the grid.

<p>One of the main benefits of switching to solar energy is the reduction you&rsquo;ll see in your electricity bill.&nbsp;</p>
<p>Installing <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> can reduce your electricity bill by <a href="https://www.boxt.co.uk/solar/guides/energy-saving-solar-panels">as much as &pound;1,180* a year</a>, so it&rsquo;s definitely worth investigating how much this renewable energy source could save you.&nbsp;</p>
<p>But, what does harnessing the sun&rsquo;s energy mean for your energy bill? Here, we explore how solar panels work with your electricity bill, how they can affect your monthly energy bill, and how you make money by selling excess electricity back to the grid. But first, let&rsquo;s take a quick look at how solar panels work&hellip;&nbsp;&nbsp;</p>
<h2>How do solar panels work?&nbsp;</h2>
<p>Solar panels are made from photovoltaic (PV) cells that absorb sunlight. This energy is then transferred into direct current (DC) electricity, before being converted into alternating current (AC), which travels through your fuse box and into your home to power appliances.&nbsp;</p>
<p>This is only a very brief description of how a solar PV system works, but for a more in-depth explanation, why not read our guide &lsquo;How do solar panels work?&rsquo;.&nbsp;</p>
<h2>How do solar panels work alongside your electricity supply?&nbsp;</h2>
<p>In this section, we explore what happens once your solar panels have been installed. Including the steps that need to be taken for you to understand how much energy you use.</p>
<p>If you&rsquo;re interested in having solar panels installed, explore our complete guide to the solar panel installation process here.&nbsp;&nbsp;&nbsp;</p>
<h3>How are solar panels connected to the national grid?</h3>
<p>Before we install solar panels for you, we will notify your distribution network operator (DNO) about the installation - typically, this is done 14 days before installation takes place.&nbsp;</p>
<p>The DNO needs to know about your solar panel system to cater for your newly generated energy and ensure their network&rsquo;s efficiency. Your region&rsquo;s DNO will inspect and test your solar panel system to ensure it&rsquo;s all working properly, too.&nbsp;</p>
<p>It is important to note that the DNO is not your energy supplier, but a regional operator that owns and maintains the wires that carry electricity from the national grid to your home. To see which DNO operates in your area, visit the <a href="https://www.energynetworks.org/customers/find-my-network-operator">Electricity Network Association&rsquo;s website</a> and enter your postcode or check out the table below:</p>

<h3>How do solar panels affect your electricity bill?</h3>
<p>Once the DNO has inspected and signed off on your system, your home&rsquo;s primary energy source will automatically switch to <a href="https://www.boxt.co.uk/solar" rel="follow">solar</a>, and you&rsquo;ll only use electricity from the national grid once the energy generated by your solar panels has been used.&nbsp;&nbsp;</p>
<p>Basically, the only difference you&rsquo;ll see is a drop in how much your energy bills cost.&nbsp;</p>
<h2>What&rsquo;s the average monthly bill with solar panels?</h2>
<p>If you invest in a solar battery, which stores excess solar energy, you could save as much as &pound;1,180 a year on your electricity bill. Discover everything you need to know about solar batteries in our complete guide.</p>
<p>Another thing to consider is how much it costs to have solar panels installed initially. For more information on paying for solar panels, take a look at our 2023 guide to solar panel prices.</p>
<h2>What factors affect solar panels&rsquo; impact on your energy bill?&nbsp;</h2>
<p>While you can expect to save a good amount of money every month with a solar PV system installed, some factors will affect how much energy your panels generate, including:</p>
<ul>
<li>The size of the solar system</li>
<li>The position of the solar PV panels and exposure to direct sunlight (panels will generate more energy on a south-facing roof)</li>
<li>Your current household energy usage</li>
<li>The cost of electricity in your area</li>
<li>Weather conditions&nbsp;</li>
</ul>
<h2>How to get the most out of your solar panel system</h2>
<p>Here are six ways to get the most out of your solar system:&nbsp;</p>
<h3 role="presentation">1. Positioning and orientation of the panels</h3>
<p>To generate the most solar power, your solar panels need to be positioned in a way that will guarantee maximum direct sunlight. Ideally, this will be on a south-facing roof, but if your property is north-facing, the panels can be oriented to produce more power.&nbsp;</p>
<h3 role="presentation">2. Regular maintenance&nbsp;</h3>
<p>Solar panels are typically low-maintenance, only needing to be cleaned and inspected every few months. Despite this, solar PV systems must be well looked after to maximise their longevity and efficiency.&nbsp;</p>
<p>A trained professional should inspect the panels annually to ensure they are in full working order and any problems can be rectified. In terms of cleaning, the rain will do most of the work for you, but a biannual clean is recommended to avoid tougher stains - like bird droppings - building up.&nbsp;</p>
<h3 role="presentation">3. Battery storage&nbsp;</h3>
<p>Batteries enable you to get the most out of your system as they reduce your reliance on the national grid, allowing you to store excess energy. This way, you can continue to save money and further reduce your carbon footprint.&nbsp;&nbsp;</p>
<h3 role="presentation">4. Smart technology&nbsp;</h3>
<p>Whether we&rsquo;re controlling our thermostats remotely from our phones or dimming the lights via Bluetooth, smart tech has revolutionised the way our homes work. Smart technology can even help you to live more efficiently and optimise your energy consumption. Discover <a href="https://www.boxt.co.uk/smart-home/guides/smart-home-technology-what-is-it">everything you need to know about smart technology</a> for more information.&nbsp;</p>
<h3 role="presentation">5. Smart Export Guarantee&nbsp;</h3>
<p>As well as helping you reduce your electricity bills, you can also make money from your solar panels too by selling excess energy to the national grid.</p>
<p>This is part of the Smart Export Guarantee (SEG), which launched after the closure of the Feed-in Tariff in 2019.&nbsp;</p>
<p>To sell excess solar energy, you must register with an SEG licensee (an electricity supplier who offers an SEG tariff) via their application processes. Each licensee has their own application process - you can find a full list of <a href="https://www.ofgem.gov.uk/publications/seg-supplier-list">SEG licensees</a> here. It&rsquo;s important to note that you don&rsquo;t have to apply to your existing energy supplier - you can apply to any provider.</p>
<p>Once approved, any SEG&rsquo;s tariffs will always be above zero, so you&rsquo;ll always receive some money for selling excess energy.</p>

How do solar panels impact your electricity bill?

Solar panels work through all four seasons. Find out what weather is best for solar panels when it comes to producing the most energy with BOXT.

<p>If you're considering making the jump to solar energy, you might be one of many people thinking that <a href="https://www.boxt.co.uk/solar/" rel="follow">solar panels</a> only work in the summer months.</p>
<p>Well, luckily for those of us living in the UK, where sunshine can often be in limited supply, this actually isn&rsquo;t true.</p>
<p>Yes, even though solar panels do need the sun&rsquo;s energy in order to generate renewable electricity, they don&rsquo;t need to be in direct sunlight in order to work.&nbsp;</p>
<p>In this guide, we'll walk you through how <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> work in winter and on particularly cloudy or rainy days to help you make the most of your solar system all year round.</p>
<h2>How do solar panels work?</h2>
<p>Solar panels are made up of smaller units called solar PV (or photovoltaic) cells. These cells are designed to convert sunlight directly into electricity.</p>
<p>When sunlight hits the surface of a solar panel, it excites the electrons in the cells, causing them to move and create an electric current.</p>
<p>While it's true that winter days are shorter and sunlight might be weaker due to cloud cover or snow, solar panels can still produce electricity as long as they receive some sunlight.</p>
<p>Read our full blog post for a comprehensive breakdown of how solar panel systems work.</p>
<h2>Do solar panels work in winter?</h2>
<p>In short, yes! Solar panels do work in winter.</p>
<p>They&rsquo;re able to operate in all four seasons of the year thanks to the fact that they can still capture the sun&rsquo;s solar energy even when it isn&rsquo;t at its most intense or direct.</p>
<p>Think about it this way; unless you&rsquo;re living inside the arctic circle and your home is plunged into months of constant darkness during the winter, the sun will still be providing light from morning to evening. So, even though it might not be sun tanning weather, your solar panels will be harnessing the sun&rsquo;s rays and converting solar energy into electrical energy.&nbsp;</p>
<p>What&rsquo;s more, thanks to recent technological advancements, modern solar panels are engineered using systems of lenses and mirrors to capture different parts of the solar spectrum and maximise energy generation.</p>
<p>Now, there is one caveat to this for UK homeowners. Since the days are shorter in the winter months and the sun is less intense than it is in summer, your solar panels won&rsquo;t operate quite as efficiently in December compared with in July.&nbsp;</p>
<p>Not a deal-breaker by any means, but just something to bear in mind when exploring <a href="https://www.boxt.co.uk/solar/" rel="follow">solar installation</a>, <a href="https://www.boxt.co.uk/solar/guides/how-many-solar-panels-do-you-need" rel="follow">how many solar panels you might need for your property</a> and whether you should consider combining solar power with a supporting energy source.</p>
<h2>How does the weather affect solar panel performance?</h2>
<p>The weather can sometimes impact the efficiency of solar panels, but this isn&rsquo;t always in a negative way. Let&rsquo;s take a closer look at the weather conditions that can actually improve the energy generating potential of your solar panel system.</p>
<h3>Rain</h3>
<p>Light to medium rainfall doesn't significantly impact solar panel performance. In fact, rain can actually help clean the panels and remove any accumulated dust or debris that might be blocking light, thus improving their efficiency.</p>
<h3>Snow</h3>
<p>During snowy periods, your solar panels will still work to convert solar energy to electricity.</p>
<p>If solar panels are completely covered in a layer of snow, it can pose a challenge to electricity generation. Luckily, experienced installers will know to tilt your solar panels at around 30 to 45 degrees, which means snow will slide off instead of building up in large quantities.</p>
<p>Additionally, the dark glass that covers solar panels holds residual heat and works to melt snow before it becomes detrimental to their panel&rsquo;s performance.</p>
<h3>Clouds</h3>
<p>Contrary to popular belief, modern solar panels actually work well in cloudy conditions. They might not be quite as efficient as when the weather is sunny but they&rsquo;ll still generate electricity when it&rsquo;s overcast.&nbsp;</p>
<p>Think about it in terms of your own relationship with the sun. You don&rsquo;t have to be lying on a beach to get sunburnt; you can get sunburn just from being outside on a cloudy day if the UV index is high enough.</p>
<p>Plus, scientists have discovered that some cloud cover can actually work in favour of your solar panels! Referring to what&rsquo;s known as the &ldquo;edge of cloud&rdquo; effect, experts show how the wispy edges of clouds can act as magnifying glasses, catching the sun&rsquo;s rays and intensifying them before they hit your solar panels.</p>
<h3>Temperature</h3>
<p>Many people are surprised to learn that solar panels are actually more efficient in colder conditions since there is greater movement of electrons at lower temperatures.</p>
<p>In fact, solar panel systems can experience some pretty serious problems in hotter regions. If the internal components within the panels overheat, hot spots and micro-cracks can form, resulting in reduced efficiency.&nbsp;</p>
<p>Ultimately, we should be thinking about solar panels as the electrical appliances that they are. Gadgets and gizmos don&rsquo;t tend to do so well when they overheat (which is why computers have built-in cooling fans), meaning lower ambient temperatures are actually ideal working conditions for solar cells.</p>

<h2>How much energy do solar panels generate in winter?</h2>
<p>If British weather is anything to go by, we know that no two winters or locations are alike. One year, we&rsquo;ll see clear-blue skies and crisp, cold days then the next will bring milder temperatures and freak snowstorms.&nbsp;</p>
<p>In practice, what this means for solar panel users is that there won&rsquo;t ever be an ultra-accurate guarantee of how much energy a solar system will generate in the winter.&nbsp;</p>
<p>What we can do, though, is use the performance data provided by manufacturers to calculate approximations for how many kilowatt hours our solar cells will provide.</p>
<p>Solar panels all have something that those in the know refer to as a temperate coefficient pMax. In layman&rsquo;s terms, this is just the percentage measure of how much a solar panel&rsquo;s efficiency is affected by temperature changes.&nbsp;</p>
<p>As standard, solar panels are power tested in controlled conditions at 25&deg;C. If, for example, a panel has a pMax of -0.5%, it means that its efficiency will reduce by 0.5% for every 1&deg;C rise or fall in the ambient temperature.&nbsp;</p>
<p>Temperature isn&rsquo;t the only factor that influences solar panel output in winter, though. A range of variables can come together to impact how much energy your solar panels will be able to generate. In <a href="https://energysavingtrust.org.uk/installing-solar-and-saving-energy/" rel="follow noopener" target="_blank">use cases cited by the Energy Saving Trust</a>, the electricity generation of some panels from November to February was only 10% of what it was in the summer.</p>
<p>This should be taken with a good pinch of salt. Even though energy production might be lower in the winter, it never falls to zero. What&rsquo;s more, you can store surplus energy generated during the summer in <a href="https://www.boxt.co.uk/solar/guides/what-is-a-solar-panel-battery" rel="follow">solar batteries</a> to make sure you have a far more consistent supply year-round.&nbsp;</p>
