What happens when it rains, snows, sleets or hails?
Update Time:2018-07-16
It doesn’t have to be entirely sunny for your panels to produce electricity. In bad weather, your power production won’t be 100%, but your panels will still be producing power. On a cloudy day, your panels might produce only 30% of what they normally would. The exception is a snowstorm. If it snows enough for there to be a significant accumulation on your panels, your panels will not produce electricity. However, snow usually slides easily off the face of the modules, and your modules tend to be located where your roof gets the most sun, so the snow on your panels will melt quickly, and your modules will resume producing electricity. If you live in an area that gets snow in the winter, snow days are likely and will be factored into your system’s projected production.
