• Solar Pumps :

    A solar-powered pump is a pump running on electricity generated by photovoltaic. The operation of solar powered pumps is more economical and has less environmental impact than pumps powered by an internal combustion engine.

    A solar powered pump thus consists of 4 parts :

    -  the actual fluid pump (that actually moves (pumps) gases or liquids under pressure)

    -  the controller (adjusting speed and output power according to input from solar panels)

    -  the engine (usually an electric motor)

    -  the energy source being powered by the sun (usually photovoltaic cells (solar panels))
     
     
    Water pumping
     
    Solar PV water pumping systems are used for irrigation and drinking water in India. The majority of the pumps are fitted with a 200 watt - 3,000 watt motor are powered with 1,800 Wp PV array which can deliver about 140,000 liters of water/day from a total head of 10 meters. By 30 September 2006, a total of 7,068 solar PV water pumping systems have been installed.
