What is it?


Tat Solar can be directly converted to electrical energy by means of Solar Photovoltaic System. Solar Photovoltaic (SPV) Technology enables the conversion of direct sunlight into electricity without involving any moving part such as turbine etc.The basic part Solar Photovoltaic is known as Solar Cell. Solar Cells are made of semi conducting materials- a thin wafers of Silicon which is exposed to sunlight, to produce D.C electric current.


       Solar power and other renewable energy sources are seeing technological advances that are making them cost effective. Rapid growth is projected. At the moment, photovoltaic power is expensive, but since we will never run out of sunlight, it is an exciting source of energy for the future! Solar water heating systems pay for themselves in three to five years. The technological challenge we face is to find ways to make solar technologies affordable for everyone.


       In developing countries the percentage of households which have no access to electricity is more significant. Most of those lacking access live in rural or peri-urban areas. Solar photovoltaic (PV) cell designed to convert light into electricity is often used to cover the electricity need of household.


    Solar PV systems provide a wide range of energy services such as lighting, electricity for radio, TV, phone, and water supply for domestic use or activities aimed to increase poor people's income like agriculture (irrigation). So PV, like other renewable energy systems, has been seen as an alternative to grid extension.


       Many reasons justify why the use of solar PV system for solar-based electricity production is an attractive option in electrification of rural and peri-urban households:
·the abundance of solar resources in most developing countries;
·the fact of the costs solar PV equipment are gradually falling;
·the interesting experiences learned in this sector. In the developing world solar PV systems have been tested, optimised and disseminated over the last 20 years;
·the PV module manufacturer, or module supplier, generally provide a minimum 10-year warranty.


Who uses it?


Solar the Photovoltaic Energy is part of Rural Revolution in the rural areas where grid power is not yet reached. In India Solar Photovoltaic System is successfully installed in large number of villages.
A household can generate most of the electricity they need with photovoltaic cells on their rooftops. If there isn't enough sunlight at times, electricity can be stored in batteries for cloudy days.


Solar water heating systems pay for themselves in three to five years. The technological challenge we face is to find ways to make solar technologies affordable for everyone.



The SPV system consists of an 800/860 WP (weather permitting) photovoltaic arrangement, a permanent DC magnet motor-driven floating pump which can pump water from a depth of eight meters through the optimum of 6.5 meters. It can ideally function in a wide-mouth well with a flow rate of 70,000 liters a day. The photovoltaic modules on the solar panel captures energy from the sun and converts it into electricity. The panel is connected to the pump via a plug so that the farmer finds it easy to use. The system works as long as there is sunshine. For example in In South India, the sun is of course plentiful.


The uses of Solar PV   Solar home system (SHS) and photovoltaic pumping system (PVP) are the most proven of PV application in the field of household energy. The use of SHS is more significant than PVP.
