As the winter months set in, solar panels can continue to be a valuable energy source for your home. While the shorter days and reduced sunlight in the UK may lower energy output slightly, well-maintained solar panels can still perform efficiently, even in cold weather. Winter also brings challenges like snow, ice, and debris that can affect your system’s performance. Proper maintenance ensures your solar panels stay effective and durable throughout the colder months.
At Heat IQ, we specialise in solar panel installation and servicing across Yorkshire, helping homeowners maximise their energy savings year-round. Here’s everything you need to know about keeping your solar panels in top condition this winter.
Winter Maintenance
Solar panels are designed to withstand harsh weather conditions, but regular care is necessary to perform optimally. Winter maintenance helps prevent issues like snow build-up, ice damage, or reduced efficiency caused by dirt and grime. By taking proactive steps, you can avoid costly repairs and ensure your system generates as much energy as possible.
Keep Your Panels Clear of Snow
In the UK, heavy snowfall is relatively rare, but even a light layer of snow can block sunlight and reduce energy output. Most solar panels are installed at an angle, which allows snow to slide off naturally. However, if snow accumulates, it’s essential to remove it safely.
Use a soft-bristle brush or a specially designed snow rake to gently remove snow from the panels. Avoid using metal tools or abrasive methods, as these can scratch the panel’s surface. In many cases, simply allowing the sun to warm the panels will help melt the snow, especially if the temperature rises above freezing.
Protect Against Ice Buildup
Ice is less common than snow but can pose challenges if water pools around the edges of your panels and freezes. This can strain the mounting system and potentially cause damage. To minimise the risk, ensure proper drainage by inspecting the panel mounts and clearing any blockages.
Avoid using chemical de-icers or salt, which can erode the panel frames and reduce their lifespan. If ice does form, allow it to melt naturally rather than attempting to chip it away.
Monitor Energy Production
Winter brings shorter days and less intense sunlight, so a slight drop in energy production is normal. However, noticing a significant decline could indicate a problem with your panels or system. Use a monitoring system to track your solar panels’ output and identify potential issues early.
Check your inverter regularly to ensure it’s operating correctly. A faulty inverter can reduce your system’s overall efficiency by preventing solar energy from being converted into usable electricity.
Clean Panels
Dirt, debris, and grime can accumulate on your panels, especially during winter storms. Keeping your panels clean ensures they can absorb as much sunlight as possible. Use a soft sponge or cloth with lukewarm water to clean the surface. Avoid using hot water, as it can crack the glass if the panels are extremely cold.
Schedule cleaning on a mild day when temperatures are above freezing to prevent water from freezing on the panels. Regular cleaning not only improves efficiency but also prolongs the lifespan of your solar panels.
Mounting System
Winter weather, including strong winds and heavy rain, can stress the mounting systems holding your panels in place. Inspect the brackets and bolts for wear, rust, or loosening. A secure and stable mounting system ensures the panels remain safely in place and reduces the risk of damage during storms.
If you’re unsure about the condition of your mounts, Heat IQ can perform a professional inspection as part of our solar panel servicing.
Check for Shading
In winter, the sun sits lower in the sky, creating shading from trees, buildings, or other obstructions that may not have been an issue in summer. Ensure your panels have an unobstructed sky view by trimming any overhanging branches and monitoring nearby structures.
Even partial shading can significantly impact the efficiency of your solar panels, so it’s essential to address this issue promptly.
Keep Your System Warm
Solar panels perform better in colder temperatures, but extreme cold can affect the system’s wiring and connections. Inspect the wiring for any signs of wear or damage and ensure all connections are secure. If you notice any issues, contact a professional to repair them before they escalate.
Schedule a Professional Service
While homeowners can handle many maintenance tasks, professional service ensures your solar panels are thoroughly inspected and any underlying issues are addressed.
