Solar surface water pump system consists of solar generating systems, photovoltaic water pump controller system and pump. Solar arrays are in series-parallel of solar modules, absorbing solar radiation energy and converting it to electricity to supply power for the entire system. Photovoltaic water pump controller regulates the running system, turning instable DC of solar array into stable DC to drive DC pump, and regulates the output current in accordance with sunlight intensity to achieve maximum power point tracking(MPPT), maximizing the use of solar energy.
