READ MORESolar thermal electricity in a CSP plant is generated in two stages. In the first stage, solar energy is captured in the collectors and is used to heat a working fluid which may be water or molten salt. The second stage deals with the energy transformation in which electricity is generated by allowing steam to run a turbine or an engine.
READ MORESolar thermal energy use can be classified in one way by the temperature range achieved and the corresponding applications. It is widely used already for heating purposes (water, space) in the "low" temperature range up to about 100 °C, using mainly nonconcentrating collectors, higher temperatures can be achieved with more
READ MORESolar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power.
