The government of India set a target of installing 100GW of solar power in India by 2022. The target is divided into two parts; 60GW of ground mounted solar installation and 40GW of rooftop solar (RTS) installation. 32.62 GW of this target is already installed in India as of March 2020 out of which 32.11 GW is ground mounted installation which is approximately 50% of the target capacity and 2.51 GW is rooftop installation (MNRE, 2021). As ground-mounted solar installation increasing at a good pace RTS is still trying to make its place in the country especially in the residential sector. Attaining this target is not possible unless strict regulations are made to overcome the barriers in installing rooftop solar. The biggest barrier is lack of support from state DISCOMs in the country. DISCOMs have poor financial support, poor grid infrastructure, and irregularity in peak demand, electricity theft, inefficiency in billing, differed tariff hikes and delay in subsidy disbursement (Neeraj Kuldeep, 2019). These factors hamper the performance of DISCOMs in India. The report will analyse solar rooftop installation states on the basis of residential rooftop focusing policies, tariff, AT&C Losses, T&D Losses and CO2 emission mitigaton and will provide a business model that will benefit the DISCOM and other stakeholders and will work on the challenges.
