How Solar Panels Work
Typically, when you see a solar panel on a roof, it is a photovoltaic (PV) panel and covered with a tempered glass enclosure to protect it from the elements. Assemblies of solar cells are used to make solar panels, solar modules, or photovoltaic arrays. The basics of how the solar cell converts light energy into electricity by the photovoltaic effect can be found here.
There are numerous technology choices in terms of cells, panels, and configurations, plus so many different manufacturers creating many different types of solar panels. Get professional guidance from Pur Solar before purchasing your solar electric system.
