The Government has set determined aim of 40 GW solar rooftop PV capacity to be fulfilled by 2022. The solar rooftop installations are significantly low owing to various factors like unwillingness of banks to provide providing in rooftop sector, uncertainties of policy and regulatory framework in medium and long terms, unavailability of skilled workforce and lack of supply infrastructure. In this study The financial viability of solar rooftop system has been assessed in 10 states in India and it has been found that solar rooftop systems are already competitive with conventional power sources in Punjab, West Bengal, Uttar Pradesh, Gujarat and Himachal Pradesh in the residential sector; Uttarakhand, Dadra & Nagar Haveli, Maharashtra, Punjab, Uttar Pradesh, West Bengal in the commercial sector; all states except Arunachal Pradesh in the industrial sector. However, there are limitations like unavailability of low-cost finance which make consumers unwilling to switch to solar rooftop systems. With the developed business models, the current state of solar rooftop segment may be improved significantly. The financial modelling, with the suggested financing techniques in the developed business models, suggest that grid parity can be achieved in all sectors and in all states. For the states in which grid parity was already achieved with existing business models, the consumers may adopt the developed business models to access low cost financing and quality services for their solar rooftop installations. A power outage analysis has also been carried out and a PV-battery system was developed for resilient power supply. Although the LCOE discovered was higher than most states deploying PV only, it is expected that as battery prices fall and grid tariffs increase, the battery storage model would become feasible for many states.
