Use a small, inexpensive PV module (photovoltaic panel) to power the pump. No battery or electronic controller is used. There is no wiring to the building's electric system.
Sun-synchronous operation: pump speed varies with sunlight, corresponding to the available heat in the collector - natural automation!
This principle has proven highly reliable in solar water heaters since the early 1980s. For hydronic heating (using battery system).
Power requirement is less than half that of conventional AC pumps powered by inverter.
Additional energy savings can be realized by using individual zone pumps instead of a single pump with zone valves. This method can reduce power consumption by 75%.
Energy saving greatly reduces the size and cost of the power system required.
