Selective Solar Water Heater Systems

Solar water heater system, in its very basic configuration, consists of a collector and water storage tank.

The collector is the component which absorbs the solar radiation and heats the water that is circulated within it. In order to increase the absorption of solar radiation and reduce the reverse radiation of heat back to the atmosphere, the collector has what is called a selective surface – a treatment to provide high operation efficiency – thus the name selective water heater system
