Home Solar Energy Systems

Solar energy is produced when sunlight is used to generate electrical energy. Photovoltaic panels use silicon cells, which transform solar radiation into direct current. The energy is used simultaneously or is stored in batteries to provide electricity.
Solar energy can also be used to cook food by trapping and concentrating the sun’s heat in a cooker and to heat water or to generate steam which in turn can be utilized for mechanical applications. This is usually done by flat plate collectors which is expose a large thin surface, containing a liquid to the sun. The sun’s heat can be intensified with lenses and mirrors and stored in salts and stones.
India is making its mark in solar energy development and use. India lies in the sunny regions of the world. Most part of the country receives 4 to 7 kwh of solar radiation per square meter per day with 250 to 300 sunny days in a year. This make India potential area in solar energy. As a result solar energy development is seen all over the country.
A Solar lantern works on photovoltaic energy. It consists of photovoltaic module, CFL tube, inverter, electronics, battery and protection system. Broadly, the following home solar energy systems /products are available in the market:
Solar PV Module

A solar domestic light can be used for the lighting requirements in houses. It consists of photovoltaic module (18 w / 37 w \ 74 w), CFL of 9/11 watts, inverter, electronics battery, protection system etc.
The solar streetlights are suitable in remote areas, fields, and other applications where light is required throughout the night. It consists of photovoltaic module ( 37 / 74 watts), CFL (11 watts), battery, inverter, electronics, controls, pole and other hardware. Due to control electronics, the streetlight gets automatically switched ON at dusk, operates throughout the night and automatically gets switched OFF at dawn.
