S_3SP2-65-D24-370BI Submersible Solar Well Water Pump with Built-in Controller — High Quality Solar Fountain Water Pump Kit for Electric Cycle

Runtime estimate: If you divide the pump’s electricity consumption by a power generation efficiency of 50%, the pump can be expected to operate about 6 hours a day and 8 hours a day under those conditions. Application and design: This Solar DC brush-less series pump is suitable for agriculture, deep well water extraction, household use and similar fields. The solar panel supplies power directly; the unit automatically starts and stops and features a compact structure, modern styling and easy operation and maintenance. Sizing the solar array: To select the required solar panel capacity, first determine the pump’s input power (power consumption). Then divide that value by the solar panel’s power generation efficiency of 65% (up to 70%) — alternatively multiply the pump input by 1.5. The resulting number is the nominal solar panel power needed to drive the pump.
