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?

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?

Solar panels not working as they should? Explore 9 reasons why your energy source may be affected and what you can do to solve your solar setbacks in this guide.

<p>It goes without saying that most technology we encounter can have its off days, and <a href="https://www.boxt.co.uk/solar" rel="follow">solar panels</a> are no exception. Whilst they are a robust and reliable alternative to traditional energy sources, they are not without their faults and, as such, can degrade over time. &nbsp;</p>
<p>If you have woken up to an unresponsive heating system or your smart meter shows an ungodly spike in your energy costs, your solar panels might be having some technical difficulties. &nbsp;</p>
<p>In this guide, we share some of the most common reasons why your solar panels aren&rsquo;t working correctly.</p>
<h2>9 reasons your solar panels aren&rsquo;t working properly</h2>
<p>If your solar panel system is unresponsive, then nine times out of ten, there is usually a solution. In the first instance, it is worth taking a look at the panels themselves - if they&rsquo;re in an accessible and safe place - to gauge what the issue could be.&nbsp;</p>
<p>If you can&rsquo;t see any issues on the surface, you might need <a href="https://www.boxt.co.uk/contact-us" rel="follow">help from a professional</a> to diagnose the problem. Your solar panels not working could be from several different issues, including:</p>
<h3>1. Lack of sunlight</h3>
<p>If your solar panels are shaded or concealed by trees, buildings, or debris, they may not receive enough sunlight to perform correctly.</p>
<p>So, when installing solar panels, it&rsquo;s best to have them in a suitable location to avoid this issue. Of course, debris and rubbish can collect on the panels over time. Still, regular maintenance will keep this at bay and see your solar panels perform at their optimum efficiency.</p>
<h3>2. Faulty wiring</h3>
<p>Over time, loose or damaged connections may disrupt the flow of energy, causing panels to malfunction. Check the wiring and connectors that join the solar panels, inverters, and electrical system.&nbsp;</p>
<p>Faulty wiring often contributes to problems with solar panel connections. The most frequent issue is a poor connection between the wires and the terminals on the inverter or the solar panels. Corrosion or damage could be responsible for this.&nbsp;</p>
<p>That&rsquo;s why it&rsquo;s essential to check your solar panel connections regularly; if you suspect a problem, contact a professional, as they&rsquo;ll be able to check the system safely and test whether it is functioning correctly overall.</p>
<h3>3. Inverter issues</h3>
<p>Probably the most common issue found on faulty solar panel systems isn&rsquo;t actually the panels themselves - it&rsquo;s all down to the inverter. The inverter converts the direct current (DC) generated by the panels into alternating current (AC), which powers the electrical components around your home.</p>
<p>Whilst solar panels have a lifespan of between 20 - 25 years, an inverter&rsquo;s lifespan is much less. And, with a broken or faulty inverter, you&rsquo;d be hard-pushed to get any electricity from your panels.&nbsp;</p>
<p>Luckily, you can easily check this on the inverter, as they display helpful error messages. If you have lost electricity, ensure your consumer unit&rsquo;s solar PV breaker is turned on or up. If it trips to the off position, <a href="https://www.boxt.co.uk/contact-us" rel="follow">call a professional</a>; if it stays on, check the inverter for error messages.</p>
<h3>4. Dust or dirt on the panels</h3>
<p>When you invest in solar panels, you can expect to see an ROI (Return on Investment) within 10 - 15 years, and whilst they will deplete in performance over time, like all technology, solar panels continue to operate at a high level. However, significant yearly performance dips are not common; if this happens with your installation, then a likely suspect is dirt and debris accumulating on the panels.&nbsp;</p>
<p>Over time, as dust and debris build up, they block out sunshine, negatively impacting the solar electricity output. As mentioned earlier, you can keep on top of this solar panel fault by regularly cleaning your panels using purified water. &nbsp;</p>
<h3>5. Micro-cracks</h3>
<p>Micro-fractures, also known as micro-cracks, are a kind of deterioration in solar cells. The silicon in solar cells is extremely thin and stretches and shrinks due to temperature cycling. The increasing temperatures during the day cause the solar panels to expand then decreasing temperatures at night cause them to contract. This process is known as thermal stress.</p>
<p>If you suspect the problem, it&rsquo;s best to catch it early, as minor flaws in the silicon cell might result in larger micro-cracks. The length of micro-cracks can vary; some span the entire cell, while others exist in only small areas.&nbsp;</p>
<p>Unfortunately, if your solar panels look like they have any fractures or cracks, their time might be up - whilst they will still work to a certain degree, the overall efficiency will only continue to decrease.</p>
<h3>6. Snail trails</h3>
<p>&ldquo;Snail trails&rdquo; is the term for a brown colouration or contamination visible on the surface of solar panels. It is caused by faulty silver paste being used during the panels manufacturing process and can be a common issue.&nbsp;</p>
<p>Because of the moisture that gets into some solar panels (usually cheaper models), oxidation occurs between the encapsulating material and the silver paste. This oxidation also causes the front solar panel to break down, resulting in noticeable colouration.&nbsp;</p>
<p>This colouration degrades the performance of the solar panels, producing problems throughout the system and ultimately reducing the energy supply.</p>
<h3>7. PID effect</h3>
<p>A potential-induced degradation (PID) can not only affect the performance of your solar panels, but it will decrease the lifespan. But now you&rsquo;re probably wondering, what is the PID effect? A PID effect is when there is a potential-induced performance reduction in solar panels caused by stray currents, which may result in a power loss of up to 30%.</p>
<p>In short, it occurs when there is an unwanted electrical current leakage (or voltage discharge) between the photovoltaic (PV) cells and the grounded components of the solar panel system, such as the frame or mounting structure.&nbsp;</p>
<p>Factors that contribute to PID include:</p>
<ul>
<li>High system voltage</li>
<li>Increased humidity</li>
<li>High temperatures</li>
</ul>
<p>It&rsquo;s worth mentioning that advances in solar panel technology and improved production procedures have lowered modern solar panels&rsquo; vulnerability to PID.</p>
<h3>8. Malfunctioning breaker switches&nbsp;</h3>
<p>Your solar panels&rsquo; breaker switch (also known as a circuit switch) is the heart of and an essential part of any solar system. It is a barrier between the two electrical currents: DC (direct current) and AC (alternating current). When it comes to installation and routine maintenance, a barrier between the panels and the alternating current is required.</p>
<p>Breaker switches are installed to protect the solar panels and associated electrical components. They are intended to stop the flow of an electrical current if there is a problem, such as a high current or a failure in the system - thus helping to keep the solar panels, wiring, and other equipment in good condition.</p>
<p>If you suspect that your breaker switch is malfunctioning, then unless you are qualified to do so, it&rsquo;s best to speak to a professional electrician to take a look at the problem.</p>
<h3>9. Poor installation</h3>
<p>If your solar panel system is not properly installed, it may cause problems in the future. For example, the system may not be operating correctly, meaning it won&rsquo;t produce as much energy as it should. Also, it may be more susceptible to power fluctuations, such as during a power outage which can degrade its efficiency and diminish its lifespan over time.</p>
<p>Keep in mind that poorly installed or maintained solar panel systems are also likely to put yourself and others at risk; that&rsquo;s why it's essential to always use a qualified installer when investing in solar energy systems.&nbsp;</p>

Which is the better investment: heat pumps or solar panels? Read our BOXT blog for a comprehensive breakdown to help you make an informed decision.

<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>
</td>

<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?

Looking to get the most out of your solar panels? They may need cleaning. Take a look at our 10-step guide to cleaning your solar panels.

<p><a href="https://www.boxt.co.uk/solar" rel="follow">Solar panels</a> are becoming an increasingly popular way to generate energy for UK homes, especially in recent years with the cost of living and energy bills continuing to rise.</p>
<p>Once you've got a solar panel system installed in your home, it's good practice to have them cleaned fairly regularly. In this guide, we're going to tell you all about cleaning solar panels, answering questions like why, how and when, alongside a few tips.</p>
<p>If you're looking into solar energy, and want to see what it can do for your home, use our simple online process to find a solar panel and battery storage solution to suit your home.</p>
<h2>Why is it important to clean your solar panels?</h2>
<p>Whilst solar panels are largely self-cleaning with the help of natural elements like wind and rain that can move dust and dirt from the surface, they still need tending to from time to time to optimise their performance.</p>
<p>It may not seem particularly necessary, but cleaning solar panels is essential to maintain performance and energy production. Over time, dust, dirt and other debris can build up on the panels, meaning their access to direct sunlight can be blocked, which will reduce their efficiency.</p>
<p>Put simply, dirty solar panels won&rsquo;t perform as well as clean ones.</p>
<p>Cleaning solar panels regularly helps extend their lifespan and ensures warranty compliance if you need your appliance to be replaced further down the line.</p>
<p>It's a no-brainer: by keeping the panels clean, you can enhance their energy output, prevent damage, maintain your investment in solar energy and <a href="https://www.boxt.co.uk/boilers/guides/how-to-reduce-household-gas-usage" rel="follow">reduce your home's reliance on non-renewable energy</a>.</p>
<h2>Our 10-step guide to solar panel cleaning</h2>
<h3>The tools and materials you'll need to clean solar panels</h3>
<p>Before you get started, you'll need to get prepared with the right equipment.&nbsp;</p>
<p>Don't worry about breaking the bank over this. In most cases, you're looking at anywhere between &pound;5-&pound;30 to cover your solar panel cleaning costs, depending on what you already have available in your home.</p>
<ul>
<li><strong>Water: </strong>Distilled or filtered water is preferred for solar panel cleaning, given the fact that hard water can leave streaks on the panels and even damage them over time.</li>
<li><strong>Mild detergent: </strong>You don't need anything too industrial to clean solar panels, any abrasive cleaning substances can damage the panels. A biodegradable soap can work well.</li>
<li><strong>A sponge/brush: </strong>You'll need something with soft bristles for the surface of the panels, avoid using an abrasive sponge to avoid scratching.</li>
<li><strong>A bucket: </strong>To hold your cleaning solution.</li>
<li><strong>Drying materials: </strong>A squeegee or a simple microfibre cloth will work just fine to dry the panels, removing any excess water and giving you a satisfying finish.</li>
<li><strong>Ladder: </strong>Depending on where your panels are placed, it's likely you'll struggle to reach them without some sort of help. If your solar panels are on the ground floor, you might get by with just an extension pole.</li>
<li><strong>Safety equipment: </strong>Working with chemicals and at potential heights, there are some precautions you should take. At a bare minimum, we'd recommend gloves and goggles to protect from chemicals, if you're working at height, ensure you're wearing some sturdy, hard-wearing footwear, and head protection.</li>
</ul>
<h3>Step 1 - &nbsp;Equip your safety gear</h3>
<p>Whenever you're tackling tasks that are unfamiliar to you, safety should always come first. Make sure you have your gloves, goggles and footwear on, and that if you're working with roof-mounted panels, your ladder is secured to the ground.</p>
<h3>Step 2 - Study your solar panels</h3>
<p>When you first had your panels installed, you should've been given some manufacturer's notes. In this pamphlet, you will be able to read about any precautions or requirements for cleaning your solar panels.</p>
<p>If you've misplaced your pamphlet, it's okay, you can often find this info online if you look at the manufacturers' website.</p>
<h3>Step 3 - &nbsp;Choose your time carefully</h3>
<p>This is especially important for people cleaning their panels in the summertime or intense weather conditions. It's best to wash your panels in mild conditions, for example, early morning or late evening.</p>
<p>Intense, direct sunlight can cause your panels to dry quickly, leading to streaks and causing an unsightly finish to your hard work. From a safety point of view, if you're working at heights, don't pick a rainy day.</p>
<h3>Step 4 - &nbsp;Turn off the system</h3>
<p>It may seem simple, but this is one that many people overlook. Solar panels can carry dangerous voltages, so it&rsquo;s essential to turn them off to avoid any hazards with the electricity.</p>
<h3>Step 5 - &nbsp;Remove any heavier debris</h3>
<p>Being placed outside, you can find any manner of things discarded on the surface of your panels, like loose leaves, dirt or even pigeon nests. You can use a soft brush or broom to take care of this, ensuring that you don't press too hard to avoid scratching.</p>
<p>Top tip: Now is probably a good time to check for any potential hazards, too, things like roof cabling or loose tiling on roofs that may need to be covered or avoided when working with water.</p>
<h3>Step 6 - &nbsp;Prepare your solution</h3>
<p>Mix your cleaning product with filtered or distilled water in a bucket, following the instructions on your chosen solution to find out the ratios you need for your solution.</p>
<h3>Step 7 - &nbsp;Wet the solar panels</h3>
<p>Wet the panels a decent amount with your cleaning solution, feel free to leave it on to soak for a few minutes, to allow the solution to tackle any stubborn dirt, stains or pesky bird droppings on the panels.</p>
<h3>Step 8 - &nbsp;Scrub your solar panels</h3>
<p>Now it's time for the hard work, you're going to have to scrub all the dirt off of those panels. We'd recommend circular motions, ensuring you clean the whole panels to optimise their future performance.</p>
<h3>Step 9 - &nbsp;Rinse the solar panels</h3>
<p>Once you feel like your panels have been thoroughly scrubbed, you need to rinse off the solution and any remaining dirt. You can use a hosepipe or another bucket of clean water for this. Remember, try and use soft, filtered water to avoid any unsightly marks and damage to your panels.</p>
<h3>Step 10 - &nbsp;Dry your solar panels</h3>
<p>Now that your panels are cleaned and rinsed, it's important to dry off any excess water from the glass surface to ensure a satisfying finish and no complications with the excess solution being left on the panels.</p>
<p>From here, with your solar panels cleaned, feel free to turn them back on and continue benefiting from solar energy in your home.</p>
<h2>Not confident in cleaning solar panels yourself?</h2>
<p>If you don&rsquo;t feel confident in tackling your solar panel cleaning alone, there are countless companies you&rsquo;d be able to call upon for their services. Many standard window cleaners now also offer solar panel cleaning, so it&rsquo;s worth shopping around if you&rsquo;re not able to maintain the panels yourself.</p>
