Overview of photovoltaic technologies in India

India has a vast potential for large-scale utilisation of photovoltaic technology. The Ministry of Non-Conventional Energy Sources (MNES) is responsible for the formulation of policies, support to R&D and industries, field demonstration and large-scale applications in photovoltaic (PV) technology. The present paper gives a brief outline of the Indian programme on photovoltaics, related Government policies and discusses various issues related to development, industrial activity, field trials and related experience and commercial market development efforts in India.
