Solar panels are designed to support a certain weight, also called a load. Some panels can support more weight than others. For most signs snow weight is not an issue, but if you experience heavy snowfall in your area, be sure to choose signs with a higher load capacity. Either way, you don’t want to let the snow sit on your panels for too long; the snow prevents the panels from absorbing light and they will not produce any energy. It’s a good idea to invest in a squeegee or snow rake to clean your panels if snow accumulates there. Your solar installer can show you what works best or can even provide a cleaning service during the winter months. Most of the time, however, snow, like rain, should just slide off your panels if they are positioned at an angle. Additionally, like rain, snow helps clear panels of debris and dust, allowing your panels to achieve higher efficiencies and maximize power output. Remember to keep cars, patio furniture, or other items far enough away from your roof in case ice or snow falls off your panels.
As long as the snow remains on your panels, your system will continue to generate electricity even in the harshest winters. Remember that winter does not last forever. If you live in a state with snowy winters, you’ll likely experience the opposite in the summer with long sunny days. So even if your solar panels produce less electricity in the winter, they will compensate in the summer. Here’s another tip: Prices for solar installations are often cheaper during the winter months when overall building demand decreases. Do not wait ! There’s never been a better time to go solar.
