Solar power is energy that comes from the sun. This energy can be captured and stored in many different ways. It is the ultimate source for most energy resources. It is also used directly to generate electricity.
One common solar energy technology is the solar panel. Solar panels are composed of a series of solar cells. Each cell is able to transform light energy into electrical energy — a technology called photovoltaics (PV). “Photo” means light and “voltaic” refers to the generation of electricity.
Concentrating solar power (CSP) technologies use mirrors and lenses to reflect and refract sunlight onto collectors where it is transformed into thermal energy. It can then be used to generate electricity.
