How Solar Thermal (Solar Domestic Water Heating) Works

Solar thermal panels, also known as solar hot water collectors, transfer heat energy from the sun to water.

Solar water heating systems are connected to an existing domestic water heating system. In the event that the solar storage tank cannot meet hot water demand, the existing hot water heater is used.
