Solar production:

Solar power is currently prohibitive due to high initial costs of deployment. To spawn a thriving solar market, the technology needs to be competitively cheaper — i.e. attaining cost parity with fossil or nuclear energy. India is heavily dependent on coal and foreign oil — a phenomenon likely to continue until non-fossil / renewable energy technology become economically viable in the country.[5][6] The cost of production ranges from Rs 15 to Rs 30 per unit compared to around Rs 2 to Rs 6 per unit for conventional thermal energy.[7]
With high deployment price as the main hurdle before a solar market, various organisations have developed innovative funding schemes to catalyse solar's attractiveness.[11][12] One of the most successful example is the solar loan programme in India,
sponsored by UNEP[11] in partnership with two of India's major banking groups - Canara Bank and Syndicate Bank, and their sponsored Grameen Banks. It was a four-year $7.6 million effort, launched in April 2003 to help accelerate the market for financing solar home systems in southern India. Foreign Direct Investment up to 100 percent is permitted in non-conventional energy sector through the automatic route. The Multilateral Development Banks like World Bank and Asian Development Bank are also helping India but, the funding from MDBs on solar energy enhancement is negligible compare to other clean energy support in India.[3] Investment by private companies is a trend that has just started.[7] (Examples include Signet Solar, U.S.-based Cypress Semiconductor, SunTechnics Energy, etc.)
