Many people think temperatures dip in the winter because Earth is
farther from the sun. But in reality, Earth is farthest in July and closest in January.
The common myth is that solar panels won’t work in the winter or in
cold climates. Solar panels do in fact work during the colder months.
While heavy snowfall can reduce sunlight penetration your panels
will still be able to produce electricity.
So how can you be sure that solar panels will still perform during
winter, or in a cold climate? We’ll answer all your cold weather
questions in this post.
Let It Snow
Snow can absolutely work during snowy weather, but only if they
don’t remain covered by snow for an extended period of time.
Premium solar panels have an anti-reflective glass covering the silicon. These are designed to absorb the maximum amount of sunlight and by doing so generate more electricity. This also means the panels produce more heat from the sun, meaning it will melt snow more quickly than snow on your roof.
Panels are also designed to hold 20-40 pounds of weight per square foot, so the weight of snow usually isn’t heavy enough to be a risk.
