– Soler water heater use Energy From The Sun to generate Hot water heater Which can be used to heat water heater for showering ,Heating System, Heat Swimming pool And industrial processes.
– Flate plate collectors are the most common type.
They consist of (1) a dark flat-plate absorber, (2) a transparent cover that reduces heat losses, (3) a heat-transport fluid and (4) a heat insulating backing.
The absorber consists of a thin absorber sheet (of thermally stable, aluminum, steel or copper, to which a matte black or selective coating is applied) often backed by a grid or coil of fluid tubing placed in an insulated casing with a glass cover.
In water heater panels, fluid is usually circulated through tubing to transfer heat from the absorber to an insulated water heater tank.
This may be achieved directly or through a heat exchanger.
