SOLAR PUMPING SYSTEM

Description

A solar water pump is an application of photovoltaic technology whichConverts Solar Energy Into Electricityto run the pumping system thereby, replacing Electrical supply and pollution-causing diesel-powered versions. The solar water pump is powered by solar modules that helps draw surface or ground water out for irrigation. Betaoffers both DC and AC range of Solar Water Pumps in both Surface and Submersible categories. These pumps help reduce farmers’ dependency on expensive fuels and their maintenance costs as opposed to conventional irrigation systems. 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.[1] 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 pumps are useful where grid electricity is unavailable and alternative sources (in particular wind) do not provide sufficient energy. 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 1 kW rating, and are suitable for applications such as garden fountains, landscaping, drinking water for livestock, or small irrigation projects. Since DC systems tend to have overall higher efficiency levels than AC pumps of a similar size, the costs are reduced as smaller solar panels can be used. However, the panel and inverters must be sized accordingly to accommodate the inrush characteristic of an AC motor.Voltage of the solar pump motors can be AC (alternating current) or DC (direct current).

COST EFFECTIVE : The life cycle and the cost to ultimate beneficiary make the SPV systems cost effective as compared to conventional systems. IN addition the farmer is saved from the capital investment he has to make for drawing lines from the grid to his field/farms. The govt. may save huge resources which otherwise may be uneconomical to network every agriculture field under the state electricity grid. RELIABLE : The SPV is more reliable, consistent and predictable power option as compared to conventional power system in rural areas. Free fuel: Sunlight, the fuel source of SPV system is a widely available, inexhaustible, and reliable and free energy source.Hence the SPV system has no monthly fuel bills. BENEFITS TO FARMERS Farmer gets a high value, high discharge pumping system for a one time amount that is less than a third of the actual price and may be maintained at nominal cost annually. No fuel costs & minimal maintenance costs. More economical than diesel pump sets in the long run. Where no pumping system exists at present SPV based pumping system, Enables cultivation of an extra crop Helps in providing the critical protective irrigation in water scarce areas. Saves time and labor Improves agriculture productivity Improves general quality of life with higher levels of income Incremental income enables easy repayment loan taken for installing
