Flat Plate Solar Collector

Suitable for residential or commercial solar water heating projects, the flat plate solar collector, a key component of the flat plate solar water heater, consists of absorber plate, glass cover, insulation layer, and shell.

The metal absorber plate with coating is welded onto the red copper pipe. Cold water or other heat transfer medium is heated when running through the pipe. The transparent glass cover allows visible light to pass through but blocks the far infrared. This means sunlight can pass through the glass cover and reach the absorber to produce heat, but the far infrared produced by the absorber is kept inside. In this way, heat loss is reduced, while the heat-absorption efficiency and the temperature of the absorber are increased.

The absorber plate is usually coated with black selective coating, black chrome coating or blue titanium coating. In areas with winter temperature above 0 ℃, a solar energy collection system that directly heats cold water is applicable, but in areas with winter temperature below 0 ℃, the user could add a medium liquid in the flat plate collector to heat cold water indirectly.
