Average 2600 to 2800 hours of bright sunshine are available over the rest of the country, except Kerala, the North eastern states like Assam, and Jammu and Kashmir where they are appreciably lower due to their location and occurrence of monsoons.
India just had 10 megawatts of grid-connected solar generation capacity. As part of the National Solar Mission, the ministry aims to bolster the annual photovoltaic production to at least 1,000 megawatts a year by 2013.
With an installed capacity of 123 GW, the country currently faces energy shortage of 8% and a peak demand shortage of 11.6%. In order to sustain a growth rate of 8% it is estimate that the power generating capacity in India would have to increase to 306 GW in the next 10 years which is 2.5 times current levels.
