Solar water heater is a heating system that converts sunlight energy into heat energy, which heats water from low temperature to high temperature.
It is often installed on a balcony or open space. It can obtain sunlight, and then uses the energy from the sun to heat water and store it in an insulated water tank.
The system is not linked to electricity, so there is no on-off switch, but the system uses sunlight to heat water all day and store it in the storage water tank.
On sunny days, most solar water heaters can provide water at a temperature of about 68℃±5℃. Water from the storage tank can then be used for any application as needed.
