Solar panels generate electricity 22

Solar panels, at their essence, are composed of many photovoltaic (PV) cells, which are responsible for converting sunlight into electricity.. Solar panels, at their essence, are composed of many photovoltaic (PV) cells, which are responsible for converting sunlight into electricity.. The power efficiency of a typical crystalline silicon cell is in the 22 to 23 percent [range, meaning they convert as much as 23 percent of the light striking them into electricity]. [pdf]
