ANNOUNCEMENTS
India has got enormous solar potential having suitable geographical location. The solar roof top system is seen as one of the best proved green technologies to address the energy security issues not only in India but also globally. Hence, the Indian government has set the target to install 100GW of solar energy by the year 2022 and out of this 40GW is planned through roof top solar system. However the actual physical progress of roof top solar installations is slow and has achieved only 15% of the target at the end of Jan 2019. It would require installing almost 9 GW every year for next four years to achieve the target. Hence the main focus of this project is to analyse a small rooftop system in order to increase the installation of solar roof top particularly in the residential sector.
The study examines the Current Scenario of residential rooftop and its barriers & challenges. Based on the study a 2 KWp of system with 4.8 kWh of storage has been introduced and its benefits, uniqueness and functionality have been explained. The advantage of the system for consumer as well as Discom has been explained to upswing PV Port in residential sector. Discoms play a major role in supplying reliable and safe electricity to a large cluster of residential consumers. The study investigates the peak load flow analysis of the Discom to acknowledge the impact of storage in peak shaving. The variable cost of supply for Discom & power purchase cost from power exchanges for Discom has been compared to see discover the % of increase in cost during peak demand.
The performance of the system has been simulated on PVsyst to know the yearly yield generation. Cost Estimation for the PV port has been done roughly based on benchmark cost provided by GIZ. The study has deliberated the cost and benefit analysis on electricity tariff for consumer based on the ground of energy cost i.e. net billing before and after PV PORT installation.
An excel tool has been developed to carry out the economic evaluation of a business models. The financial analysis shows that the system is more profitable for high paying consumer & economically viable after disbursing subsidy. The study shows that IRR is more in case of middle paying & high paying consumer with NPV>0. Finally the research concludes with set of result, outcomes and future scope shows ways for improvement in the existing scenario of solar roof top in the residential sector in India.
