A solar water heater is a device that uses sunlight to heat water Residential Installation, commercial, and industrial use. Solar water heaters can be a cost-effective way to generate hot water because solar power is free and they don't emit carbon dioxide.
Absorbing sunlight: Specialized panels absorb sunlight and convert it into heat energy.
Transferring heat: The heat is transferred to a storage tank to ensure a continuous supply of hot water.
Active: Have circulating pumps and controls
Passive: Don't have circulating pumps and controls
Flat-plate collectors: The most common type of solar collector. They consist of an insulated box with a dark-colored absorber plate, covered with a transparent cover.
Evacuated tube collectors: More efficient than flat-plate collectors. They consist of a series of glass tubes containing a vacuum.
