As the chilly winter months approach, many homeowners with solar panels begin to wonder how their systems will perform in less-than-ideal weather conditions. At Furber Roofing, we often receive questions about the efficiency of solar panels during winter and how to keep them operating at peak performance despite the shorter days and colder temperatures.
Understanding Solar Panel Performance in Winter
It’s a common misconception that solar panels don’t work well in the winter. The truth is, solar panels can still produce energy in cold weather, and in some cases, they may even perform better than in the summer. Here’s why:
- Temperature and Solar Efficiency: Solar panels are made of photovoltaic cells that convert sunlight into electricity. These cells work more efficiently in cooler temperatures. While it may seem counterintuitive, too much heat can reduce the efficiency of solar panels. Therefore, during the winter months, when the air is cooler, your solar panels may actually operate more efficiently.
- Sunlight Availability: Although winter days are shorter, your solar panels are still able to capture sunlight. Even on cloudy days, solar panels can generate energy. It’s important to note that solar panels do not require direct sunlight to function—they only need daylight. Thus, even on overcast winter days, your panels will continue to produce electricity, albeit at a reduced rate compared to sunny days.
- Snow and Solar Panels: Snowfall can temporarily cover solar panels, blocking them from capturing sunlight. However, most solar panels are installed at an angle, which helps snow slide off. Additionally, panels generate a small amount of heat when exposed to sunlight, which can help melt the snow. While snow may reduce energy production for a short period, it generally doesn’t have a long-term impact on overall performance.
Tips for Maintaining Solar Panels in Winter
To ensure your solar panels continue to perform efficiently throughout the winter, it’s important to take a few maintenance steps. Here’s how you can keep your system in top shape:
- Regularly Monitor Your Solar Panel System
During winter, it’s essential to keep an eye on your solar panel system’s performance. Monitoring software provided by your solar installer, such as the ones we recommend at Furber Roofing, allows you to track your system’s output. If you notice a significant drop in energy production, it could be due to snow coverage, debris, or another issue. By monitoring your system regularly, you can address any problems quickly and ensure your panels are working as efficiently as possible.
- Keep Solar Panels Clean and Free of Debris
Winter storms can bring not only snow but also leaves, dirt, and other debris that can accumulate on your panels. While snow typically slides off, other debris might not. Keeping your panels clean will help maximise their exposure to sunlight. If you’re comfortable doing so, you can use a soft brush or a specialised solar panel cleaning tool to gently remove debris. However, if your roof is steep or difficult to access, it’s safer to hire a professional cleaning service, like those offered by Furber Roofing, to take care of the job for you.
- Be Cautious When Removing Snow
If snow accumulation becomes an issue, you might be tempted to remove it yourself. However, it’s crucial to approach this task with caution. Using metal tools or harsh chemicals can damage the surface of your solar panels. Instead, opt for a roof rake with a soft, rubber edge specifically designed for solar panels. This tool allows you to gently pull the snow off without causing any damage. Additionally, never attempt to clear snow from panels if your roof is icy or slippery—your safety should always come first.
- Consider Professional Inspection and Maintenance
Before winter sets in, consider scheduling a professional inspection of your solar panel system. At Furber Roofing, our expert team can check for any issues, such as loose wiring, damaged panels, or potential shading problems that could impact your system’s efficiency. A thorough inspection can catch minor problems before they become major issues, ensuring that your solar panels are ready to perform at their best throughout the winter months.
- Ensure Your Roof Is in Good Condition
Your roof plays a critical role in supporting your solar panels. A strong, well-maintained roof is essential for the longevity and performance of your solar energy system. Winter weather can be tough on roofs, so it’s important to ensure that your roof is in good condition before winter arrives. At Furber Roofing, we offer comprehensive roofing services, including repairs and maintenance, to keep your roof in top shape. By addressing any roofing issues early, you can prevent potential damage to your solar panels and maximise their efficiency.
Maximising Solar Panel Efficiency Year-Round
While winter poses some challenges for solar energy production, with proper care and maintenance, your system can continue to operate efficiently year-round. By following the tips outlined above, you can ensure that your solar panels remain free of debris, snow, and damage, allowing them to capture as much sunlight as possible—even on the shortest, coldest days of the year.
It’s also worth considering the long-term benefits of solar panels, especially when it comes to winter energy bills. With energy costs typically higher in the winter, the energy produced by your solar panels can help offset your heating expenses, leading to significant savings over time.
