Equality between economic progress and environmental sustainability is essential for a developing country like India. In the present time, the economy of India is growing rapidly in a vibrant mode and an efficient way, which in turn demands huge uninterrupted energy supplies. The country's energy needs are met mostly by the usage of fossil fuels and nearly 70% of electricity is generated from coal based power plants. In India, nearly 840 million people depend on traditional biomass to satisfy their energy necessities. Approximately 74 million rural people do not have access to modern lighting systems and around 81 million households do not have access to electricity, which is a major challenge to India's energy security. In order to achieve stable sustainable energy in the long-run, significant progress in renewable energy sectors is needed. Favorably, due to India's geographic location, the country is blessed with abundant renewable energy resources, which has not yet been exploited completely. So the central and state governments of the country have framed various policies and are providing subsidies to encourage the utilization of solar photovoltaic systems. In this paper, a comprehensive review of the potential, current developmental status and prospects of solar energy of India is briefed. The various applications of solar energy such as water heaters, desalination units, pasteurizers, food drying units, water purifier, space heating systems, air-conditioning units, cookers, water pumps, aerators, solar-wind hybrid systems and grid connected photovoltaic systems are explained. The study also mentions the current renewable energy policies, the barriers blocking the progress of the solar manufacturing units and some possible future recommendations that might speed up renewable energy developments in India.

The mitigation of global energy demands and climate change are the most important factors in the modern days. Development and application of solar energy have been regarded by the government of India and common people, and they thought that solar photo voltaic 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 progress of current solar photovoltaic energy in India. It highlights the renewable energy trend in India with major achievements, state wise analysis of solar parks and industrial applications. Finally, it discusses the Indian government policies and initiatives to promote solar energy in India. This review on solar photovoltaic energy will help decision makers and various stakeholders to understand the current status, barriers and challenges for better planning and management in this field.

There are two ways by which solar energy can be harnessed viz. solar Photo-Voltaic (PV) and Concentrating Solar Power (CSP). This paper focuses on the parameters required for the commissioning of solar power plants in India using these technologies. The key parameters have been identified through the literature review and discussion with the experts. The parameters thus obtained, are classified under PV and CSP technologies and then categorized into technical and economical parameters. A survey is conducted to understand the perceptions of Indian key players in the area of solar energy and to rank forty one identified parameters. Analysis of survey shows that location of the site and direct investment cost are the highest preferred technical and economical parameters respectively. The results of this study will help decision makers and policy makers of solar technologies in India. [ABSTRACT FROM AUTHOR]
