The short answer is yes, solar panels do work when it's cloudy, but they don't make as much power. Even though this is a big drop, it doesn't mean that cloudy days are useless for solar cells. Solar panels do not need direct sunlight to work. That said, they won't produce the same amount of electricity as they would on a sunny day. Evaluate the Installation's Impact, 2. Enhance Surrounding Visibility, 4. Modern photovoltaic (PV) systems. .
