5T/H 50M Solar Submersible Deep Well Pump — Brushless Permanent Magnet Synchronous Motor for Home, Agriculture & Water Circulation

This solar-driven submersible pump runs directly from photovoltaic panels and features automatic start/stop control. It is built with a compact, modern structure designed for easy operation and straightforward maintenance. The pump employs a brushless permanent magnet synchronous motor, which offers high efficiency and can reduce the required solar array size for the same output power. Note on solar sizing: if you size the solar array by dividing the pump input power by 70%, the panels will typically deliver rated power for only about 3 to 4 hours per day; during the remaining sunlight hours the output will not meet the pump's rated requirements. To properly size panels, first determine the pump’s input power. Then account for solar generation efficiency by dividing that input power by 65% (up to 70%) — alternatively multiply the pump input by 1.5. The resulting figure is the nominal solar panel power needed to reliably run the pump.
