Do you ever worry how your solar panels will perform during the cold winter months? As the days get shorter and temperatures drop, many homeowners might assume that solar panels are less effective in the winter. However, with a bit of preparation, your solar panel system can continue to generate clean, renewable energy—even when there’s snow on the ground.
In this guide, we’ll walk you through the steps you can take to ensure your solar panel system is winter-ready!
1. Don’t Worry About Cold Weather—Solar Panels Love It!
A common misconception is that solar panels don’t work well in cold weather. The truth is, solar panels are actually more efficient in cooler temperatures. Just like other electronics, they perform better when they aren’t overheating, which means that clear, sunny winter days can still be highly productive for your solar energy system.
The real challenge in winter is not the cold, but the reduced daylight hours and the possibility of snow covering your panels. That’s where a little preparation can go a long way.
2. Keep an Eye on Snow Build-up
One of the biggest concerns for solar panel owners in winter is snow build-up. While a dusting of snow won’t affect your system’s performance too much, a heavy accumulation can block sunlight and reduce energy generation. Luckily, most solar panels are installed at an angle, which helps snow slide off naturally.
Living in the UK fortunately means that you won’t have to worry about much snow! But if there does happen to be any snow fall this year, a quick check and gentle sweep of your panels can prevent days of lost energy production.
3. Inspect Your Panels for Winter Wear and Tear
Before winter sets in, it’s a good idea to give your solar panel system a thorough inspection. Check for any dirt, debris, or damage that could impact the performance of your panels during the colder months.
Look for cracked glass, loose wiring, or any signs of wear on the mounting system. Winter weather can sometimes exacerbate existing issues, so addressing them beforehand can save you headaches later on.
Pro tip: You don’t have to go it alone. If you’re unsure about the condition of your system, consider scheduling a professional inspection with us at PHS. Our experts will make sure that everything is functioning correctly, and your panels are ready to handle whatever winter throws at them.
4. Maximise Winter Sunlight Exposure
With the sun sitting lower in the sky and daylight hours at a minimum, every bit of sunlight counts during the winter months. To maximise energy production, make sure nothing is obstructing your panels.
Trim back any tree branches or nearby shrubs that might cast shadows on your system. Even partial shading can have a big impact on how much energy your solar panels produce, especially when daylight is already limited.
5. Monitor Your System’s Performance
Winter can bring unpredictable weather, from clear skies to snowstorms, so it’s important to keep an eye on your solar panel system’s performance. Many systems come with monitoring tools that allow you to track energy production in real time.
By checking your system regularly, you can quickly spot any issues, such as reduced output due to snow, shading, or malfunctions. This allows you to address problems immediately, rather than discovering them after weeks of reduced energy generation.
6. Consider Energy Storage for Winter Efficiency
While solar panels can still generate power during winter, the shorter days mean you might produce less energy overall. One way to ensure you have enough power for your needs is to invest in an energy storage system, such as solar batteries.
With energy storage, you can store excess energy produced on sunny days and use it during periods of low production or at night. This can help keep your home powered during the darkest days of winter, reducing your reliance on the grid and keeping energy bills in check.

Pro tip: If you already have a battery system in place, now is a great time to check that it’s working correctly and can handle the extra demand during the winter months.
7. Routine Maintenance: Don’t Skip It
Like any home system, your solar panels require routine maintenance to keep them running efficiently. Winter is an excellent time to ensure that everything is in top condition, from the panels themselves to the inverter and other system components.
In addition to your pre-winter inspection, schedule regular check-ups to ensure your system is performing at its best. At PHS, our knowledgable experts can regularly inspect your solar system and fix any issues. A well-maintained system is more likely to withstand the rigours of winter without any major issues!
