It’s a common misconception that solar panels lose their productivity during the winter months, but we’re here to set the record straight! Not only do solar panels perform well in the winter, but they can also be even more efficient in colder temperatures. This is great news for solar system owners in New Hampshire and other cold-weather regions. Below, we address some of the most frequently asked questions about how solar panels perform during the winter season.
Do cold temperatures cause panels to freeze?
You might think solar panels would freeze and lose productivity in cold weather, especially in regions where temperatures frequently dip below freezing. However, the opposite is true—cold weather enhances solar panel efficiency.
Solar panels generate energy when electrons move in response to sunlight. While winter brings shorter days, snow, and cloud cover, which reduce sunlight exposure, the colder temperatures allow electrons to experience a more significant energy shift. This results in higher energy output compared to warmer weather. So, despite the chilly conditions, your solar panels remain productive and efficient.
Does snow block panels from sunlight?
Any obstruction on your solar panels can prevent sunlight from reaching the covered areas, reducing the amount of energy your system generates. While snow can slightly lower productivity during the winter months, its impact is typically minimal. Snow usually melts quickly when exposed to sunlight and easily slides off sloped roofs.
Should I clean snow off my panels?
We strongly advise against clearing snow off your solar panels, as it can pose risks to both your safety and the panels’ condition. Climbing onto a roof, particularly in icy conditions, can be dangerous and increase the likelihood of injury. Additionally, using any snow removal tools on the panels can cause scratches, which may reduce their efficiency. Instead, we recommend allowing sunlight and gravity to handle the snow removal.
What if the snow doesn’t come off my panels naturally?
Although snow rarely stays on solar panels for long, certain weather conditions may cause it to linger. To address this temporary lack of sun exposure, we recommend investing in a battery backup system. It stores excess energy generated by your solar system when it’s sunny, ensuring you maintain a reliable energy supply even on days when snow or clouds limit direct sunlight on your panels.
Conclusion
Winter doesn’t have to mean a drop in solar productivity. Cold temperatures can enhance the efficiency of solar panels, and while snow may temporarily reduce sunlight exposure, it typically slides off or melts quickly without causing significant issues. By letting nature handle snow removal and investing in a battery backup system, you can maximize your solar power year-round!
