Your solar panels will only collect energy if they are exposed to the sun. When they get covered by snow, even in a small patches, their energy output may be drastically reduced. If your home is connected to the grid, that's not a big problem — you'll still have access to power. If you live off-grid, however, it's important to. There are several options for homeowners who have snow on their solar panels. Wait for the snow to melt. Most solar panels are installed at an angle and face the sun, which helps the panels to absorb solar energy. This also means that when the sun rises, the snow can. Ultimately, the amount of energy collected during cold winter months is very low — the days are shorter and the amount of sunlight reaching your panels will be minimal. Fortunately, because most on-grid solar energy systems work through a credit system, the energy. If your solar panels aren't installed at an angle, consider having them adjusted or reinstalled so that accumulated snow can more easily slide off. Orienting your array southward is another good.
