A:Solar energy is always around us. The only major difference is that on cloudy days, the amount of energy available is lower. Your solar panels will continue to collect this energy, but they do so at a lower rate, and that means they don’t produce as much useable electricity as they would otherwise. You as a homeowner likely won’t notice a difference—your lights and appliances will all still work as normal. However, for these days you will need to draw more energy from the public grid in order to meet your demands.
