Submersible Solar Well Pump with Built-in Controller for Electric Cycle — High Quality Solar Fountain Kit S_3S1.8-100-D48-400BI

Solar DC brushless series pumps are suitable for agriculture, deep well water extraction, household use and similar applications. The unit is driven directly by solar panels and features automatic start/stop operation, a compact footprint, modern styling and easy maintenance. If you base the calculation on a 50% power-generation efficiency, the pump can be rated for about 6 hours a day and 8 hours a day. To size the solar array: first determine the pump input power, then divide that value by a solar panel power-generation efficiency of 65% (up to 70%) — or multiply the input power by 1.5. The result is the nominal solar panel power required to run the pump.
