The "Grid Level Energy Storage Problem" Solar and wind provide "intermittent" electricity, meaning their energy production changes depending on the weather. People often need energy when the wind is not blowing or the sun isn''t shining, so we can end up with too much electricity at some times, and not enough electricity at other times.

PV cells, or solar cells, generate electricity by absorbing sunlight and using the light energy to create an electrical current. The process of how PV cells work can be broken down into three basic steps: first, a PV cell absorbs light and knocks electrons loose. Then, an electric current is created by the loose-flowing electrons.
