National Solar Mission - best practices guide on implementation of state-level solar rooftop photovoltaic programs in India

The Ministry of New and Renewable Energy (MNRE), Government of India has announced an ambitious solar target of 100,000 megawatts (MW) installed capacity by 2022, of which 40,000 MW of solar photovoltaic (PV) systems are to be installed on rooftops. There have been several efforts at the policy, regulatory and implementation levels for solar rooftop deployment in India. For a long time, the country witnessed solar installations with the help of Government funding, which has now started evolving to various public-private partnership (PPP) and private sector-based models. However, the net capacity of such projects has till now remained limited, especially compared to the regulatory and procedural efforts undertaken to realize such projects. This Guide attempts to lay out a comprehensive and efficient solar PV rooftop implementation support process into a single document. It captures global and national best practices and learnings. The Guide primarily addresses grid-connected rooftop PV systems, under both net metering and gross metering connectivity.
