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.

Solar vacuum collectors help in generating solar hot water, even in cold, wet & windy conditions. This is due to the low thermal losses from the collector. Thermal losses caused by conduction & convection are eliminated. This enables the collector to be very effective in utilising low amounts of radiation.   The tube is made from glass with unique properties that gives it good transmissibility with low reflection losses & durability. High absorption of solar energy is achieved by using an absorber. The main assembly parts of the absorber are the absorber plate and the heat transfer tube. The absorber plate is coated with a special high efficiency selective coating that ensures maximum thermal radiation losses.
