In most cases, there is no need to clear snow from the solar panels. In light snow, light can pass through the panels, and in heavy snow, the 45-degree angle of most platforms makes it easier to slide through the snow. In addition, the darker color of the panels is warmer than the ambient temperature, which helps accelerate the melting of the snow cover.
The snow that rolls off the panels actually serves another useful purpose: it keeps the device clean and dust-free, improving its performance.
However, there are times when you may want to consider intervention. First, since the panels are already heavy, any really significant extra weight from snow can overload the roof. But remember that most panels (and roofs) are designed to withstand significant extra weight and undergo rigorous stress testing to prove it.
If you intervene, under no circumstances climb onto a snow-covered roof or attempt to remove snow . This is very dangerous and could result in a fall or serious injury. Also, do not attempt to remove snow with tools not specifically designed for cleaning solar panels, as you may seriously damage the panels.
If you're worried about too much snow in the winter, you can buy a solar rocket that rises about 20 feet into the air and allows you to safely remove snow from your panels. Be sure to check your warranty as sometimes trying to remove snow can void your warranty.
If you have a significant amount of snow accumulation and are really concerned that it will violate the energy production or weight limits of the roof, hire a professional to remove the snow from your roof.
