| The term solar collector commonly refers to solar hot water panels, but may refer to installations such as solar parabolic troughs and solar towers; or basic installations such as solar air heaters. Solar power plants usually use the more complex collectors to generate electricity by heating a fluid to drive a turbine connected to an electrical generator.[1] Simple collectors are typically used in residential and commercial buildings for space heating. | | The term solar collector commonly refers to solar hot water panels, but may refer to installations such as solar parabolic troughs and solar towers; or basic installations such as solar air heaters.

| A solar pond is simply a pool of saltwater which collects and stores solar thermal energy. <br> The saltwater naturally forms a vertical salinity gradient also known as a halocline, in which low-salinity water floats on top of high-salinity water. The layers of salt solutions increase in concentration with depth. Below a certain depth, the solution has a uniformly high salt concentration. | | A solar pond is simply a pool of saltwater which collects and stores solar thermal energy. <br> The saltwater naturally forms a vertical salinity gradient also known as a halocline, in which low-salinity water floats on top of high-salinity water.
