Solar panels use photovoltaic cells that release electrons when sun shines on them. This creates an electrical current. Inverters turn it into useable power.

Solar panels use sunlight to generate electricity, but they can do it around the clock, even when the sun isn't shining. Here's how.

Solar panels do work on cloudy days, because despite cloud cover — which blocks, reflects, and absorbs sunlight — some diffused sunlight still penetrates through to reach the panels.
