The short answer is yes, solar panels do work when it's cloudy, but they don't make as much power. Each panel contains many solar cells, usually made from silicon, that absorb sunlight. When sunlight hits these cells, it excites the electrons, creating an electric current. This direct current (DC) then passes. . While direct sunlight produces the highest output, modern solar technology ensures you're not left powerless when the sky turns grey. 2 Do Solar Panels. .
