Solar Water Pumping System

A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps.

The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact than pumps powered by an internal combustion engine (ICE).

Solar pumping system consist of 3 main parts:

  1. Solar Panels : The solar panels make up most (up to 80%) of the systems cost. The size of the PV-system is directly dependent on the size of the pump, the amount of water that is required (m³/d) and the solar irradiance available.
  1. The Controller : 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
  2. The Pump : Voltage of the solar pump motors can be AC (alternating current) or DC (direct current). Direct current motors are used for small to medium applications up to about 4 kW rating. Alternating current solar pump with inverters extends from 0.15 to 55 kW and can be used for larger irrigation systems.

Advantages

Solar powered water pumps can deliver drinking water as well as water for livestock or irrigation purposes. They may be especially useful in small scale or community based irrigation and require much less maintenance. Solar pumps are useful where grid electricity is unavailable and alternative sources (in particular wind) do not provide sufficient energy. Separate parts of the system can be easily carried to the remote areas which allows the saving of energy and also cost.
