This is a submersible solar-powered water pump designed for wells, boreholes, or deep water sources.
It runs on 24 V DC — powered directly by solar panels (no need for grid electricity or diesel).
It’s marketed for a 50-metre lift/head — meaning it can draw water from up to 50 m deep.
Water flow rate is roughly 1,500 litres per hour (≈ 1.5 m3/hr) under ideal conditions.
In other words: this is a “deep-well solar pump” — intended for boreholes or wells, not surface-water suction from shallow wells or rivers (unless shallow and pumped from near-surface).
