Solar Water Heater Circulation Pump, PV Direct Drive

Description

Solar Circulation Pump, PV (Photovoltaic) Direct Drive

*0 Watt nominal power water pump designed to run off a solar photovoltaic panel, most likely application is for water circulation in a split solar thermal water heater system. The pump can be used for anything, but the designers had in mind solar hot water systems with solar panels split from the hot water tank, which necessitates a circulation pump.

Makes simplest split solar water heater system.

Runs with either *0 W or *5 W solar PV panel

Circulation pump runs when the sun shines

Runs faster when more sun, more hot water

No controller, no probes, no grid power needed

Can make off-grid split solar water heater system

Pump electronics are specifically designed to run with variable output from a solar photovoltaic panel. This pump is specifically designed to work as a circulation pump for solar thermal water heater split systems. Pump can start with little sun and uses Maximum Power Point (MPP) tracking to run faster when there is more sun, and therefore more heat to be taken from the solar thermal panels.

Eliminates the need for an electronic control system for solar energy water heaters. Radiant floor heating also possible.
Electronic controllers historically cause the most trouble in a solar water heater system. Eliminate the controller with a solar PV direct pump, and the largest source of solar water heater system failures is eliminated.
