Solar Thermal Energy
An infographic showing how solar thermal energy can be harnessed for heating homes. The collector is a large plate with a black coating that readily absorbs the Sun''s energy. The heat is transferred to a fluid inside tubing attached to the plate. The fluid is usually a mix of water and anti-freeze so it can survive cold winter nights.

Where temperatures below about 95 °C are sufficient, as for space heating, flat-plate collectors of the nonconcentrating type are generally used. Because of the relatively high heat losses through the glazing, flat plate collectors will not reach temperatures much above 200 °C even when the heat transfer fluid is stagnant. Such temperatures are too low for efficient conversion to electricity.
