Solar Energy in India

India Map

India is endowed with rich solar energy resources. The average intensity of solar radiation received on India is 200 MW/KM square (megawatt per kilometer square). India has a vast potential for renewable energy sources, especially in areas such as solar power, biomass and wind power. The current installed capacity of renewable energy is around 9220 MW, constituting about 7.3 percent of India’s total installed generation capacity of 146 GW.

India has presently just above 12 megawatts of grid-connected solar generation capacity that has been added only since year 2009. As part of the National Solar Mission, the ministry aims to bolster the annual solar power generation to at least 1,000 megawatts by the year 2013. It can be seen from the map that Rajasthan, Gujarat, West Madhya Pradesh and North Maharashtra receive more than 3,000 to 3,200 hours of bright sunshine in a year. Over 2,600 to 2,800 hours of bright sunshine are available over the rest of the country, except Kerala, the North-Eastern states, and Jammu & Kashmir where they are appreciably lower.

Tamilnadu has reasonably high solar insolation (5.6-6.0 kWh/sq.m) with around 300 clear sunny days in a year. Southern Tamilnadu is one of the most suitable regions in the country for the development of solar power projects. With substantial solar insolation in thes, the strong commitment of the State Government and rapidly declining Solar Power costs, there are remarkable opportunities in the solar energy domain. Renewable technologies will enhance energy security, making Tamilnadu the global reference in the solar energy sector.

Considering this huge potential market for solar energy the government has announced various incentives and programs to promote PV industry in terms of increased indigenous manufacturing, increased power generation from solar, increased industry participation in R&D and technology development.
