Submersible Well Solar Water Pump with Built-in Controller — DC Brushless for Water Circulation & Electric Cycle

A Solar DC brush-less submersible pump designed for deep wells, agricultural irrigation, household water supply and circulation. The unit accepts direct PV input and features a built-in controller that enables automatic start/stop. Its compact construction and modern design make operation and maintenance simple and convenient. Performance note: if the available electrical output is reduced to 50% (i.e., electricity consumption divided by the power generation efficiency by 50%), the pump can be rated to run about 6 hours a day and up to 8 hours a day. Panel sizing guidance: first establish the pump’s input power (power consumption). Then divide that figure by the solar panel’s power generation efficiency of 65% (up to 70%), or multiply the pump input by 1.5. The result is the nominal solar panel power required to supply the pump.
