Why can solar energy generate electricity on cloudy days

Because solar panels rely on light, not heat, they can still generate power on cloudy or rainy days at a reduced capacity. On average, they produce 10% to 25% of their normal energy output under overcast conditions. Even though this is a big drop, it doesn't mean that cloudy days are useless for solar cells. If solar is a good. . Solar panels use sunlight to generate electricity, but they can do it around the clock, even when the sun isn't shining. Solar energy is one of the most accessible and cleanest forms of energy we have. Find out how efficiency changes in different weather and how to optimize your solar system on cloudy days. [pdf]
