Solar power

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.

Solar cell

Energy; Solar power

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect.

Passive solar

Energy; Solar power

Technologies that capture sunlight for heat energy without use of active mechanical systems such as fans or pumps (as contrasted to active solar). Such technologies convert sunlight into usable heat ...
