Snowing

Solar panels snowing

When snow builds up on the surface of the panels, it can block sunlight from reaching the solar cells, reducing the system's efficiency and overall energy production. . If you live in a snowy area and have solar panels—or you're thinking about installing them, you've probably wondered the same thing every winter: Do I need to remove snow from my solar panels? And if so, what's the easiest way to do it? The short answer: In most cases, you don't need to do anything. . Solar panels, technically known as photovoltaic (PV) systems, are engineered to convert sunlight directly into electricity. This is because, like with many electric devices, solar panels can overheat when it's too hot. When the heat is extreme, this may even cause them to fail and shut down entirely.
