Solar water heating converts the sun's rays into a cost-effective way of generating hot water for residential buildings.
Solar water heating systems collect the sun's thermal energy and use it to heat water for homes and businesses. The system can be installed in any climate to reduce utility bills and consists of three main components: solar collectors, insulated pipes and a hot water storage tank.
Solar water heating systems and solar photovoltaic (PV) systems both involve collector panels, however, they are different technologies. Solar water heating systems use the sun's radiation to generate heat for water, while PV systems generate electricity.
Solar water heating systems can rely on electric pumps for water circulation (active) or thermodynamics (passive). Active solar water heating systems are more common for residential and commercial use. Passive solar water heating systems are usually less expensive, but also less efficient.
