Residential Solar Roof Top PV (RSRTPV) is a nascent technology and though India is a sun kissed land, yet the PV technology has not gained momentum by way of installations of roof tops in the residential sector. The objective of this study is to get an insight into the purchase behavior of the residential solar roof top adopters in the city of Chennai, South India. The study is based on primary data which was collected using a questionnaire. This RSRTPV adopter centric research of 105 respondents was conducted in the city of Chennai in South India. A structured, undisguised, questionnaire with 46 preselected questions was adopted after pilot testing. The length of the survey questionnaire was kept optimum with close-ended questions based on Likert scale to elicit quick responses, by the sampled adopters. The demographic variables of the respondents indicate the green profile of a PV adopter. The study reveals their domestic consumption details like the nature of RSRTPV system, its size, type of installation, roof top area, type of dwelling and the financial option of the consumers etc. reflecting the characteristic status of RSRTPV installations. The study concludes that consumers' experience, purchase behavior, knowledge of technology, its beneficial effects, accessible information on installations and customized financing options are vital inputs for aggressive market development of RSRTPV. The study also concludes that residential solar roof top segment remains the least developed, with its small transaction size, lower tariff and less third-party ownership. The study identifies the need for consumer awareness to translate into interest in and adoption of RSRTPV. Chennai has 8.69 million population, while it has only 350 MW of roof top solar, which implies that the offtake is poor owing to loans and subsidies, not being nattractive to induce adoption.

China is the world’s largest producer of photovoltaic -PV power with total installed solar capacity surpassing the early leaders in solar energy developed countries viz;USA, Germany, Japan,Italy,France, and UK.The electricity consumption of China exceeds that of any other nation and China is also the top-most solar producer with fast- growing PV systems. This paper focuses on Residential Solar PV and the progress made by China-its evolution of solar policies,trends, challenges overcome, progress made and the future of sustainable solar energy development envisaged by China.A comparison of the trajectory of growth in Residential Solar PVs in India is made to analyze the concrete government policies in this segment and the consistency and growth of RSTPV in India. The challenges faced by India and the reasons for slow growth in this sector are explored.The time is now ripe for India to focus on the RSTPV segment while implementing the Jawaharlal Nehru National Solar Mission(JNNSM) and learning lessons from China’s experiences to become a global PV leader in harnessing solar energy.
The present study attempts to understand the concept of commoditisation and its potential impact on Roof Top Solar (RTS) PV in India. Solar PV is a growing industry and it is beginning to play a major role in the electricity mix in our country. The objective of this study is to understand the need for India to commoditise PV for effective implementation, bringing about a paradigm shift in harnessing energy from the abundant freely available sunshine. Commoditization can be a prerequisite for enhanced and speedier adoption of PV even in homes. The study is based on the secondary data collected from Research articles, renewable energy journals and websites of solar energy organisations. The study helps understand the elements and the factors responsible for commoditisation which can culminate in aggressive market development of RTS. Assessing India's stance to bring about rapid commoditisation and how best to tackle the problems encountered in the Indian scenario are elucidated. The basic idea of the researcher is to lay emphasis on producing a roof top model that can be plugged in a socket to produce your own energy.The study concludes that potential challenges like effective net metering implementation, grid connectivity, fragmented electricity market, thrust for green financing etc. have to be addressed to trigger the growth of RTS.
