Moreover sustainable energy security is the another key issue which stimulate to think the researchers, manufacturers and government to develop the solar energy extensively. Development and application of solar energy have been regarded by the government of India and common people, and they thought that solar photovoltaic energy can provide more energy in future compare to other renewable energies. In the last decade, solar photovoltaic energy research and development has supported by the central government and state governments. This paper discusses the solar energy potential, development and future prospects in India. Some key policies and initiatives undertaken by Indian government to promote solar energy in India are also highlighted. Techno economic analysis of a typical roof top solar system is also analysed with Indian context which will be helpful for decision makers and various stakeholders.

INTRODUCTION India has been a witness to chronic energy poverty and almost one fifth of its population is without access to electricity. This also explains why India's per capita electricity consumption is among the lowest in the world as shown in Fig. 1[1]. Furthermore, the availability of electricity in many areas is limited to a few hours during the day. Thus, at present, a significant amount of demand is unmet owing to limited availability and accessibility of electricity. Fig 1: Per capita consumption of electricity in India As per the Maximum Energy Security Pathway scenar io predicted by “IESS – 20471 Tool” developed by Niti Aayog, Government of India (GOI), India's electricity demand, which was 876 Terra Watt-hour (TWh) in 2012 could rise up to 5518 TWh by 2047 in the case of „Determined Effort‟ or default case scenario – the level of effort which is deemed most achievable by the implementation of current policies and programs of the government. If heroic efforts were made to reduce energy demand, the same could be brought down to 3730 TWh by 2047[2].The solar energy development, challenges, policies, frameworks, Government of India (GOI) initiatives, future perspectives etc have been outlined in the literatures[3-8].
