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?

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>

<li><strong>Environmental impact:</strong> if you&rsquo;re keen on reducing your carbon footprint, you need to know that the production of polycrystalline panels involves melting silicon, which consumes a lot of energy. Of course, nearly all manufacturing processes have some kind of environmental impact, but we can't ignore the fact that certain ones generate more greenhouse emissions than others.</li>

<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>

<p><a href="https://www.boxt.co.uk/boilers/guides/are-heat-pumps-worth-it" rel="follow">Heat pumps</a> and <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> are becoming increasingly common in UK homes. 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>
</td>

<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?

Explore everything you need to know about the process of installing solar panels here, including whether you can do it yourself and how long it takes.

<p>Thinking of getting <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> installed at your home? Good idea - the benefits of living more sustainably, both on the planet and in your wallet, are plentiful.&nbsp;</p>
<p>Solar is one of the most accessible types of renewable energy and, with the <a href="https://www.gov.uk/green-deal-energy-saving-measures" rel="follow">UK Government offering grants</a> to help you fund solar panel installation, it could prove to be a frugal investment.&nbsp;</p>
<p>But how are solar panels installed? Here, we explore the whole process, from choosing the right solar panels for your home to maintaining them once they have been installed.&nbsp;</p>
<h2>How to choose the right solar panels for your home</h2>
<p>Before we get into the installation process, it&rsquo;s important to understand the different types of solar panels and which could be best suited for you and your home. To help you choose the right solar panels, there are four key factors that you must consider:</p>
<h3>1. The cost of solar panels</h3>
<p>The first factor you&rsquo;ll want to understand is the cost of the solar panels, both in terms of the upfront cost and when you can expect to get a return on your investment.&nbsp;</p>
<p>Although the cost will be one of your top considerations, you shouldn&rsquo;t be totally put off by potentially high prices. Cheaper options may not be the most efficient or not have the longest lifespan. &nbsp;</p>
<h3>2. The quality of solar panels</h3>
<p>The average <a href="https://www.boxt.co.uk/solar" rel="follow">solar panel system</a> will last around 25 years, but this all depends on the manufacturer, the quality of the materials used, and how well they are maintained. When you&rsquo;re researching which solar&nbsp;PV system to buy, make sure you read customer reviews to see if they&rsquo;re satisfied with the product and services.&nbsp;</p>
<p>At BOXT, all of our solar panels come with a 15-year warranty, and we can install them in as little as two weeks. &nbsp;</p>
<h3>3. The efficiency of the solar panels&nbsp;</h3>
<p>According to <a href="https://www.ofgem.gov.uk/information-consumers/energy-advice-households/average-gas-and-electricity-use-explained" rel="follow noopener" target="_blank">Ofgem</a>, the typical UK home uses around between 5 and 12kWh of energy per day. Before selecting a system for your home, you should be confident that the solar panels can generate enough electricity to handle your household&rsquo;s energy consumption.&nbsp;</p>
<p>To maximise the use of the solar energy generated and avoid losing excess energy back to the national grid, many people turn to solar batteries, which retain energy.&nbsp;</p>
<h3>4. The location and size of your home</h3>
<p>Before investing in solar, you should review whether it&rsquo;s viable by reviewing the direction your home faces and the number of solar panels you can reasonably fit on your roof. These factors will greatly impact the amount of solar power you can generate.&nbsp;</p>
<p>The energy output of a solar panel is measured in watts and the number of watts a panel can generate is, ultimately, linked to the size of the solar panel. The more watts, the bigger the panel.&nbsp;</p>
<h2>How many solar panels do you need?</h2>
<p>The number of solar PV panels you&rsquo;ll need depends on your current energy consumption, the size of your roof and the amount of sun your roof is exposed to per day.&nbsp;</p>
<p>According to Ofgem, the average 2-3 bedroom home will use 2,900KwH per year (8kWh per day). If you have a south-facing roof, that&rsquo;s not obstructed by trees, 10 solar panels could generate up to 4,000kWh of energy per year - around 1kWh per panel per day.&nbsp;</p>
<p>The output of a solar PV panel depends on several factors, so before committing to a number of solar panels, we recommend speaking to professional solar panel installers about your energy demands and what&rsquo;s viable based on your home and roof.&nbsp;</p>

We break down variable factors such as different sizes, how much energy each panel generates, how to calculate what you need and whether it is possible to take yourself completely off-grid using solar panels.

<h2>Can you install solar panels yourself?</h2>
<p>While it&rsquo;s not illegal to install your own <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a>, we do not recommend it. Solar panel installation is a complex job that involves handling electricity, which can be dangerous if you don&rsquo;t know what you&rsquo;re doing.</p>

<h2>How are solar panels installed?</h2>
<p>It&rsquo;s not always necessary to have solar panels installed on your roof; however, it is advantageous because it doesn&rsquo;t take up garden space or most roofs are angled in a way that helps ensure maximum sunlight.&nbsp;</p>
<p>These 8 steps outline our team&rsquo;s solar panel installation process:&nbsp;</p>
<h3>1. Construct the scaffolding&nbsp;</h3>
<p>If we&rsquo;re installing solar panels on the roof of your home, the first step is to set up scaffolding to ensure a good level of safety while the work is in action.&nbsp;</p>
<h3>2. Build solar panel mounts</h3>
<p>The second step is to build the solar panel mounting system - the mounts are the frame and base that solar panels will be fitted into, so these must be securely fastened to the roof using roof anchors. The whole mounting structure must be tilted too, to ensure maximum exposure to the sun - between 18 and 36 degrees is best.&nbsp;</p>
<h3>3. Install the solar panels</h3>
<p>Once the mounts are built, it&rsquo;s time for us to install the solar panels onto the structure. At this stage, our team double- and triple-check everything is tightly fastened and bolted down.&nbsp;</p>
<h3>4. Wire up the solar panels&nbsp;</h3>
<p>The next steps in the solar panel installation process are to connect everything, starting by wiring the solar panels. We recommend turning off your home&rsquo;s electricity supply at this stage, to avoid any accidents.&nbsp;</p>
<h3>5. Install the solar inverter</h3>
<p>Now the solar panels are wired up, it&rsquo;s time for us to install the inverter. The inverter converts the energy produced by the solar panels into usable electricity. Solar inverters are usually installed close to the solar panels, e.g. in the roof space. We can advise on the best placement for this before we start the installation.</p>
<h3>6. Connect the solar inverter and battery</h3>
<p>If you have bought a solar battery storage system to retain excess electricity and stop the energy you don&rsquo;t use from being sent to the national energy grid, we will install this next.&nbsp;</p>
<p>When the battery is being installed, we advise to keep this close to the inverter, to minimise voltage loss and maximise the solar electricity that has been generated.&nbsp;</p>
<p>Check out our <a href="https://www.boxt.co.uk/solar/guides/what-is-a-solar-panel-battery" rel="follow">complete guide to solar battery storage</a> for more information on how these devices work.</p>
<h3>7. Wire the inverter into the fuse box (consumer unit)</h3>
<p>Now the battery, inverter and solar panels are all installed and connected, it&rsquo;s time for us to connect the inverter to the fuse box so you can make the most of the solar energy, reduce your carbon footprint and save money on your electricity bills.&nbsp;</p>
<h3>8. Test the solar panels</h3>
<p>Finally, it&rsquo;s time to switch everything on and test your new PV system and make sure your solar panels work. When we&rsquo;re happy everything is working as it should be, that&rsquo;s the solar panel installation process complete!&nbsp;</p>
<h2>Maintaining solar panels</h2>
<p>Maintaining solar panel systems is pretty straightforward, although you should inspect them every few months to ensure they&rsquo;re clean. If solar panels get dirty, e.g. from bird droppings or leaves, they will not work as efficiently.&nbsp;</p>
<p>Before you start cleaning your solar panels yourself, you should consult the manufacturer&rsquo;s warranty, the terms and conditions of this may stipulate that only a professional can clean the PV panels.&nbsp;</p>

Solar panel installation: what’s the process?

Asking yourself “how many solar panels do I need?”. Before making an investment, check out our helpful guide to help your work out your solar panel requirements

<p>When switching to renewable sources of energy, you won&rsquo;t want to misjudge or overestimate the installation (otherwise, it wouldn&rsquo;t be very efficient). So you&rsquo;ll need to ask yourself &ldquo;how many solar panels do I need?&rdquo;, before making the investment.&nbsp;</p>
<p>Luckily, the team at BOXT have put together an extensive guide to how many <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> are typically needed for the average UK household.&nbsp;</p>
<p>We&rsquo;ll break down variable factors such as different sizes, how much energy each panel generates, how to calculate what you&rsquo;ll need and whether it is possible to take yourself completely off-grid using solar panels.</p>
<h2>What different sizes of solar panels are available?</h2>
<p>A solar panel's size is usually measured in <strong>watts (W)</strong> or <strong>kilowatts (kW)</strong>, which correspond to the panel's power output. Below are some typical solar panel sizes:</p>
<ul>
<li><strong>Small-scale panels: </strong>Usually measuring 1 metre by 1.6 metres, these panels have power outputs between 100 and 350 watts. They are appropriate for small-scale domestic uses such as supplemental grid power, battery charging, and powering a single appliance.</li>
<li><strong>Standard residential panels: </strong>These panels typically have a power output of between 250 and 425 watts and range in size from 60 to 72 cells. They are appropriate for smaller installations and rooftops in private residences.</li>
<li><strong>Commercial panels: </strong>These panels are intended for commercial or industrial applications and are larger than residential panels. They frequently feature 72 to 96 cells and have a 400 to 600 watt output per panel.</li>
<li><strong>Utility-scale panels: </strong>Finally, as the name suggests, utility-scale panels offer a much higher power output and are employed in large-scale solar power plants. They can range in size from 72 to 144 cells or more, and each panel can generate up to 500 watts of power.</li>
</ul>
<p>The number of people living in a household is one of the determining variables in calculating what size solar panel you&rsquo;ll need.&nbsp;</p>
<p>For example, an average household of 2-3 people uses roughly 2,900 kWh of power annually, therefore, standard residential solar panels would be ideal. However, if you&rsquo;re a van dweller then you may want to consider installing small-scale solar panels, as your demand for energy will be considerably less.</p>
<h2>How much energy can a typical solar panel generate each year?</h2>
<p>The typical solar panel generates between <strong>170 and 350 watts per hour</strong>, depending on the location and the weather. This equates to approximately 0.17 to 0.35 kWh per solar panel.</p>
<p>This means that a 4 kW solar power system on an average-sized home can generate up to <strong>3,000 kWh of electricity each year</strong>, which also accounts for the number of hours of sunlight.</p>
<p>However, a solar panel's annual energy output is determined by a number of variables, including the panel's size, efficiency, position, orientation, shading, and local weather conditions.</p>
<p>Roughly, each different sized panel can produce up to:&nbsp;</p>

<h2>How many solar panels do you need?</h2>
<p>When choosing solar energy for your home, you will need to take into account the aforementioned factors such as; the size of your home, the amount of people living in the property, the amount of energy you consume, and of course, your budget.&nbsp;</p>
<p>It can cost anywhere between &pound;3,000 - &pound;18,000, or above, to install solar panels.

<h2>How to calculate the number of solar panels your home needs</h2>
<ol>
<li><strong>Find your home&rsquo;s annual electricity usage: </strong>A household&rsquo;s energy consumption can be determined by its energy bills. With this information, you&rsquo;ll be able to understand how much energy your solar panels will need to generate daily. For instance, your daily energy use amounts to 4 kWh if your monthly consumption for a typical 30 day month is 120 kWh. This implies that the solar system should produce 4 kWh everyday on average.&nbsp;</li>
<li><strong>Decide on the solar panels you&rsquo;re going to use: </strong>As aforementioned, standard residential panels (4kW unit) are the most popular in the UK. However, if you are looking for a larger or smaller unit then there are options available.&nbsp;</li>
<li><strong>Establish how much suitable installation space you have available: </strong>One of the most important variables to consider, alongside budget, is how much space you have to install solar panels.&nbsp;</li>
</ol>
<p>Among this, you&rsquo;ll need to take into account the different variables that will affect your solar panels efficiency, and whether they are <a href="https://www.boxt.co.uk/solar/guides/are-solar-panels-worth-the-investment" rel="follow">worth the investment</a>.&nbsp;</p>
<p>Note that separate regions in the UK have different sun hours per day: With on average, England having 4.1, Scotland has 3.7, Northern Ireland 3.2 and Wales 3.3.</p>
<h2>Can you go completely off-grid using solar panels?</h2>
<p>While going off-grid with solar panels is a possibility and can give you energy independence, it also requires &nbsp;careful planning, routine system maintenance, and consideration of your energy consumption patterns to guarantee a reliable power source.</p>
<p>Things you&rsquo;ll need to consider before going off-grid:&nbsp;</p>
<ul>
<li><strong>Space: </strong>Do you have adequate space to install and store all the equipment that makes energy independence possible? These include batteries, solar panels, an inverter, water tank(s) and, in some cases, a backup generator. &nbsp;</li>
<li><strong>Affordability: </strong>Installing solar panels and relying on renewable energy can be a huge investment, so it&rsquo;s best to understand whether it is right for you and your needs before taking the financial leap.</li>
<li><strong>Longevity:</strong> If you&rsquo;re planning to stay in your home for a number of years then going off-grid might be a good idea, however, if you plan to move it could make the home harder to sell on the housing market.</li>
</ul>

How many solar panels do you need for your home?

Find out whether you need planning permission before installing solar panels on or around your home from the green energy experts at BOXT.

<p>With energy bills rising to unprecedented highs and everyone looking for ways to live more environmentally consciously, solar panels are becoming an increasingly attractive option for many UK homeowners.</p>
<p>As a nation, we&rsquo;re all on a journey towards achieving net zero carbon emissions by 2050, and a large part of this effort will involve changes at an individual level. Using <a href="https://www.boxt.co.uk/green-homes/guides/best-green-ways-to-heat-your-home" rel="follow">cleaner, more renewable energy sources</a> such as solar power is something that we are all being encouraged to embrace, not only for the environment&rsquo;s sake but also to help <a href="https://www.boxt.co.uk/boilers/guides/how-to-reduce-household-gas-usage" rel="follow">bring down our gas and electricity bills</a>, too!</p>
<p><a href="https://www.boxt.co.uk/solar/" rel="follow">Solar installation</a> isn&rsquo;t quite as simple as rocking up to your local hardware store and buying a few sets of the most efficient model, though. In some cases, you&rsquo;ll need to apply for planning permission before fixing them to your home&rsquo;s roof, exterior walls or garden.</p>
<p>Confused? Don&rsquo;t worry, BOXT is here to help! In this guide, we&rsquo;ll walk you through everything you need to know about getting planning permission to install solar panels so that you can start reaping the benefits for years to come.</p>
<h2>First things first: What is planning permission?</h2>
<p>Before we get into the technicalities of whether or not you&rsquo;re going to need planning permission to install solar panels on or near your property, we need to understand what planning permission actually is!&nbsp;</p>
<p>The vast majority of us will never have been in a position where we&rsquo;re embarking on our very own Grand Designs project (whether that&rsquo;s building our dream home or knocking up a small extension to house that much-needed utility room), so we&rsquo;re unlikely to have found ourselves needing to apply for planning permission.&nbsp;</p>
<p>Planning permission isn&rsquo;t just for large-scale building projects, though; it&rsquo;s also a requirement in some instances that involve making major changes to an existing building or structure. The point of planning permission is to prevent the construction of any inappropriate developments that would impact negatively on the overall aesthetics of a location, threaten wildlife and natural features, compromise historically significant buildings, or just generally worsen the quality of life of local residents.</p>
<p>Think about it this way. Would you be over the moon if a replica of The Shard appeared at the end of your street or garden? Probably not.</p>

<h2>Whose responsibility is it to apply for planning permission?</h2>
<p>For any building or modification project, regardless of whether you&rsquo;re doing it yourself or getting the help of specialist contractors, the responsibility of applying for planning permission lies with the owner of the property in question.</p>
<p>Now, we&rsquo;re not going to spend time going into the finer details of what a planning permission application involves. Any applications must be made directly to your local authority, and all the information can be found on the <a href="https://www.gov.uk/planning-permission-england-wales" rel="follow noopener" target="_blank">official government website</a>.</p>
<p>One thing to note, though, is that failure to apply for planning permission before starting a construction project can result in you being served an enforcement notice. This is a formal order to effectively undo any of the changes that you&rsquo;ve made to your property or plot of land without having permission to do so, meaning it&rsquo;s mission-critical that you obtain planning permission before starting!</p>

<h2>Who doesn&rsquo;t need planning permission for solar panels?</h2>
<p>Since the UK government recently extended its <a href="https://www.gov.uk/government/publications/permitted-development-rights-for-householders-technical-guidance" rel="follow noopener" target="_blank">Permitted Development</a> rules, homeowners typically don&rsquo;t need planning permission to install solar panels on their property. Of course, as with all policies and regulations, there are specific criteria which need to be met in order for <a href="https://www.boxt.co.uk/solar/guides/whats-the-solar-panel-installation-process" rel="follow">solar panel installation</a> to be deemed a permitted development. These are as follows:</p>
<ol>
<li>Solar panels are not to be installed above the ridgeline (that&rsquo;s the horizontal line that runs the length of your roof where the two sloping sides meet at an apex).</li>
<li>Once installed, the panels cannot protrude more than 200mm from the roof or wall&rsquo;s surface.</li>
<li>If you are installing solar panels on the ground surrounding your home, the panel system cannot be more than 9m2 and 4m tall or sit within 5m of any boundary lines.</li>
</ol>
<p>As long as you don&rsquo;t plan on breaching any of the above restrictions, you shouldn&rsquo;t need planning permission to install home solar panels.</p>
<h2>Who does need planning permission to install solar panels?</h2>
<p>If you live in one of the following properties or areas, you&rsquo;re going to need planning permission before you can have solar panels installed:</p>
<h3>1. Flat-roofed buildings</h3>
<p>It&rsquo;s difficult for <a href="https://www.boxt.co.uk/solar/guides/whats-the-solar-panel-installation-process" rel="follow">solar panel installations</a> to satisfy the requirement to sit no more than 200mm from the surface of a roof or wall on flat-roofed properties since the panels will need to be mounted at an angle of between 5&deg; and 10&deg; to ensure maximum sun exposure. This means that if your home has a flat roof onto which you want to install solar panels, you&rsquo;re going to have to apply for planning permission.</p>
<h3>2. Listed buildings</h3>
<p>A listed building is, essentially, a monument, so any maintenance and building work has to honour the building&rsquo;s history. Sadly, solar panels haven&rsquo;t been around for long enough to be considered historical features. If you live in a Grade I or Grade II listed building, you&rsquo;ll either need to apply for planning permission or <a href="https://historicengland.org.uk/advice/planning/consents/lbc/" rel="follow noopener" target="_blank">Listed Building Consent</a> before installing solar panels anywhere on your home&rsquo;s exterior.</p>
<h3>3. Conservation areas&nbsp;</h3>
<p>Like listed buildings, conservation areas exist to protect the architectural and historic features of an area. It may be possible to install solar panels under Permitted Development rules in a conservation area, but you&rsquo;ll need planning permission if you want to install solar panels on a wall facing a road.&nbsp;</p>
<h2>What else might you need before installing solar panels?</h2>
<h3>Building regulations</h3>
<p>Regardless of whether you need planning permission to install solar panels, you must make sure that you meet any building regulations before getting them fitted. These aren&rsquo;t the same thing, and, in some cases, you may end up needing both.&nbsp;</p>
<p>Building regulations are needed to ensure that any structural work carried out on a property, be it residential or commercial, is done safely and to a high standard. Within the context of installing solar panels, the key areas to note are the structural and electrical safety of the building in question.&nbsp;</p>
<p>The assessment will involve a building surveyor inspecting your property to establish whether your roof is going to be able to support the weight of the panels once installed. It will also, if necessary, provide you with a list of upgrades that are required before any panels can be installed.</p>
<h3>Structural reports</h3>
<p>The last thing anyone wants (especially the people living in a property, whether that&rsquo;s you or your tenants) is the roof collapsing under the weight of solar panels! To prevent this from happening, structural reports are sometimes recommended prior to installation. A qualified conveyancer will need to carry out a thorough inspection of your roof to establish whether there are any weak spots requiring upgrades or reinforcement.&nbsp;</p>
<p>If you have just moved into your home or know that a full valuation has been performed relatively recently, you probably don&rsquo;t need to get a structural report before installing solar panels. But, if your property is older, hasn&rsquo;t been inspected for many years, or you suspect that it might have been damaged in any way following a storm, it&rsquo;s worthwhile making the extra investment in a structural report.&nbsp;</p>
<h3>Electricity network applications</h3>
<p>In some cases, you&rsquo;ll need to <a href="https://www.gov.uk/government/publications/register-energy-devices-in-homes-or-small-businesses-guidance-for-device-owners-and-installation-contractors/register-energy-devices-in-homes-or-small-businesses-guidance-for-device-owners-and-installation-contractors" rel="follow noopener" target="_blank">seek the approval of your local authority&rsquo;s DNO</a> (Distribution Network Operator) before installing solar panels. This is in case any upgrades to your home&rsquo;s electricity supply network will need to be made in order for you to connect solar panels safely. This is something that the installer of the solar panel system will need to check and, where necessary, notify your area&rsquo;s DNO.</p>
<h2>How to get help when buying solar panels</h2>
<p>Solar panels are a fantastic investment, both in terms of helping to reduce your home&rsquo;s energy usage and bills and adding real value to your property should you ever come to sell.&nbsp;</p>
<p>Despite their incredible benefits, figuring out what&rsquo;s what when it comes to solar panels can feel like a bit of an impossible task! With advanced technology and unfamiliar regulations at every turn, it&rsquo;s no surprise that many homeowners feel overwhelmed at the prospect of getting solar panels installed on their property.</p>
<p>Don&rsquo;t worry, though, BOXT is here to help. We&rsquo;re cutting through the noise of the solar panel industry to make it easier and more affordable for you to make them a feature of your home.
