Solar Information

Why Solar

Solar Energy is undergoing a silent revolution in India. Many of us are looking for ways to reduce pollution by going solar which is a powerful and direct way to help protect the environment,. The falling prices of Solar panels are on the verge of coincidence with the growing cost of grid power in India.

Global Solar Scenario

The Global solar market is expected to have an installed capacity of 227 Gigawatts(GW) by 2016. Global solar installations, meanwhile, are expected to reach 46.8 GW per annum in 2016, up from 19.8 GW in 2011, with a Compounded Annual Growth Rate (CAGR) of 18.7 percent during the same period.

Technology Cost

The installed capacity of solar power has grown at a rate of 40 percent per year over the last decade. As the industry has grown, the prices have seen cost reductions of 22 percent for each doubling of cumulative capacity over the last few decades.

Advantages of Solar Power

Solar Energy provides the best viable solution to ensure long term energy sustainability with the following advantages:

  • Abundant, constant and perennial source, predictable.
  • Solar resource is much more evenly distributed across the state
  • Low gestation period
  • Available during the day time, helping in peak demand.
  • Can be generated at the point of consumption.
  • Reduced Transmission & Distribution losses
  • No fuel cost
  • Clean & green power i.e. no emission of CO2, Sox, Nox etc.
  • Much firmer and complements Wind Energy.

In case of Solar Photovoltaic (SPV) technology, the plant can be established from few KW to 100s of MW and it is also easily scalable.

If SPV plants are established very near to Industrial Estates, the power produced can well be utilized at the same location drastically reducing T&D losses. Huge investment needed for transmission infrastructure could also be prevented.

Solar Thermal Power Generation has an additional advantage of storing of heat energy, which can be used to produce electricity during non sunny days.

Solar Energy Association

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.
