Solar Power Plant

Product Details:

A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available through collected sunlight as opposed to grid electricity or diesel run water pumps. As such, Solar Water Pumping System can act as a stand-alone system operating directly on power generated by Solar Photovoltaic Modules during the daytime.

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 can be uses for lifting water from tubewell, Shallow wells, Ponds, Canals for either drinking water in or for irrigation purpose.

From Railway's point of view, solar pumps can be useful at remote places particularly at way side stations; level crossings etc. where grid electricity is unavailable and alternative sources (in particular wind) do not provide sufficient energy. Alternatively these can also be used at small colonies and independent houses and may be used with water harvesting system.

Technical specification issued by Ministry of New and Renewable Energy under Jawaharlal Nehru National Solar Mission for solar photovoltaic water pumping systems is as under:

A Solar Photovoltaic(SPV) Water Pumping System consists of:

• PV Array : Capacity is normally in the range of 200W to 10 kW. These ranges of Solar Photovoltaic(SPV) Water Pumping Systems are basically for “Irrigation” applications. However, these may also be used for “Drinking Water Applications wherever such capacities are required”. PV Array should be mounted on a suitable structure with a provision of tracking the sun.
