Solar power

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 power

dye-sensitised solar cell

Energy; Solar power

A dye-sensitised solar cell is a low-cost thin film solar cell that absorbs light by a sensitizer on the surface of a semiconductor. Then photo-induced electrons are injected from the dye into the ...

solar energy technologies

Energy; Solar power

Convert solar energy to useful purposes. They can provide: electrical generation by heat engine or photovoltaic means; space heating and cooling in active and passive solar buildings; potable water ...

solar hot water

Energy; Solar power

Water heated by the use of solar energy.

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 ...

solar power

Energy; Solar power

Also called solar energy, solar power is electricity generated from sunlight, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power ...

solar heat gain

Energy; Solar power

Measurement of the amount of solar heat that is captured for use by a solar collector surface including a solar roof, solar siding or ground-mounted solar system. A typical measure is Btu per hour ...
