Cutaway illustration of a solar thermal collector panel, part of a solar water heating system. Thermal energy from the sun heats fluid circulating through the pipes in the solar collector panel, which is mounted on the roof of a building. The fluid may be water which is heated directly, or a 'heat transfer fluid' which heats water by passing through a heat exchanger coil in a hot water tank. | |
