Will snow affect the condition of my solar panels?

Except in some extreme cases, the weight of snow will not hurt your panels. All solar panels are assigned a pressure rating which measures the amount of pressure a panel manufacturer is willing to guarantee for the integrity of their product. Most panels are rated for a load of 5,000 or more Pascals (Pa), which equates to two to four feet of snow, depending on the snow’s density

Most industry experts recommend you should not attempt to remove snow from solar panels. Doing so may void your solar panel warranty, or worse, you could injure yourself. In most cases, the sun melts the snow off solar panels much quicker than many think - generally thawing quicker than the ground or even your roof. Ground mounted panels are also often installed at an angle, so when the storm blows through even heavy snow should slide right off.

When your panels are covered with snow, they won’t be able to produce solar energy. However, losing out on a day or so of production isn’t worth risking your warranty or safety.Did you know, solar panels actually work better when it’s cold than when it’s warm? Like a lot of electronics, solar systems have a negative temperature coefficient. This means they experience less resistance and can generate more electricity in colder weather. The only reason your system output is less in the winter is because days are shorter.
