Solar batteries store the excess energy generated by your solar panels, which can then be used to power your home during gloomy, rainy days, or after the sun sets.
Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage. Below, you can find resources and information on the basics of solar radiation, photovoltaic and ...
Solar photovoltaics. Solar photovoltaics (often referred to as "solar cells" or "solar panels") is an electric power system which converts solar radiation from the sun (i.e., the sun''s light energy) into direct current (DC) electricity. A typical solar PV system will feature solar panels which absorb this sunlight and convert it into ...

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.
