ABSTRACT:
A constant temperature solar water heater switch, for operating a solar water heating element, using an electrical motor, and a water pump, the water pump pumping water from a water source to the solar water heating element, which uses the solar rays to heat the water, and then returning the water to the source. This system matches a solar PV panel to a compatible relay, using a variable resistance to adjust for desired operation of the system, in order to shut the system down when the sun is not shining directly, and sufficiently to heat the water in the solar heater element, in order to prevent cool water to re-enter the source.
A manual electrical overide switch is provided for manual operation of the system, for manual operation, or, for preventative maintenance.
