S_3SP2-35-D12-150BI Submersible Solar Well Pump with Built-In Controller — Solar Fountain / Electric Cycle Kit

This solar DC brushless submersible pump (model S_3SP2-35-D12-150BI) is designed for applications such as agriculture, deep well water extraction, household water supply and solar fountains. The unit is powered directly from PV panels and features automatic start/stop operation. Its compact construction and modern styling make it easy to operate and maintain. Operating estimate: using a power generation efficiency assumption of 50%, the pump can be rated for 6 hours a day and 8 hours a day. For correct solar sizing, first identify the pump’s input (power consumption). Then account for solar array efficiency — divide the pump input by 65% (up to 70%), or multiply by 1.5 — to arrive at the nominal solar panel power required to run the pump.
