ABSTRACT
The programme for the development of photovoltaics in India began in the mid-1970s and has grown to be one of the largest national programmes in the world. Early R&D efforts to develop the technology for the fabrication of silicon solar cells were followed by a programme for pilot production and development and demonstration of systems for various applications. Commercial production of photovoltaic products began around 1985. R&D projects presently being funded cover thin film technologies and system development. Specifications and test procedures have been developed for commonly used systems. Test facilities have been established at four locations in the country. The Ministiy of Non-conventional Energy Sources has been implementing a countrywide programme for the deployment of photovoltaic systems for a variety of applications. Among the systems being disseminated through a subsidy programme are solar lanterns, home lighting systems, street lights, water pumps and small power plants for villages. An experimental programme for installation of grid-connected power plants is also in progress. Among systems, which have reached a full stage of commercialisation, are those used in telecommunications, railways, oil & gas industry, broadcasting, etc. The Indian market is likely to develop into one of the largest markets for photovoltaic products in the world. The paper gives an overview covering all aspects of the photovoltaic programme in India and discusses the potential for future growth.
