Solar pump, Shape : Rectangular

A solar-powered pump is a pump running on electricity generated by photovoltaic panels as opposed to grid electricity or diesel run water pumps.A photovoltaic solar powered pump system has three parts :

• The pump
• The controller
• Solar panels

The purpose of the controller is twofold. Firstly, it matches the output power that the pump receives with the input power available from the solar panels. Secondly, a controller usually provides a low voltage protection, whereby the system is switched off, if the voltage is too low or too high for the operating voltage range of the pump.
