Sunlight passes through the glazing and is incident on the absorbing plate, which is heated, there is a change of solar energy into heat energy. Heat is transferred to liquid passing through the tubes fixed in the absorber plate. Sunrain absorber painted with "selective coatings."
The fluid is circulated through the system, and absorbs heat from sunlight falling on collectors. The heated fluid then passed to heat exchanger storage tank.
Solar collector composed of the thermal part to absorb solar radiation and heating of the fluid and photovoltaic portion for charging or powering 12V systems, including, to drive small pump at a constant current, the bundled with the collector.
Thus, if a pump powered directly on the photovoltaic panel, it will rotate depending on the intensity of solar radiation, the more sun the faster the pump and heats the hot water tank.
Pump powered by a DC voltage
Connect the pump to the heat system analysis
