How do solar panels work? A simple explanation

This energy finds its way to particles in the panel called electrons. The added energy ''excites'' the electrons and allows them to move around. They move towards a metal strip called an electrode and this causes an electric current. The current then flows out of the solar panel and into whatever it''s connected to. That''s the basic summary.
