We answer your questions regarding operating your solar power systems during periods of heavy snow.
Will the weight of heavy snow damage them?
Should I clean the snow off my solar panels to improve power production?
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.
What does this mean for the amount of energy my solar PV system produces?
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.
