Under the Indo-German technical cooperation, Government of Germany is cooperating with India and has commissioned a project through the German Climate Technology Initiative (DKTI). The project Indo-German Solar Energy Partnership – Photovoltaic Rooftop Systems (IGSP-PVRT) is financed by German Federal Ministry for Economic Cooperation and Development and implemented by GIZ in partnership with Ministry of New and Renewable Energy (MNRE), Government of India. The project aims to support MNRE in achieving the 40 GW targets announced for rooftop solar power plants under the National Solar Mission.
Government of India is aiming for an exponential increase in the installation of renewable energy systems in the country including 100 GW capacity of solar power by 2022 out of which 40 GW shall is targeted on rooftop. In March 2018, the cumulative installed capacity of rooftop photovoltaic systems was around 1063MW. The contribution from the residential segment is very small (<25%). To achieve the 40 GW target until 2022 implies close to 8GW installation every year for next five years. Such large capacity addition can occur when the photovoltaic systems are installed through a mass movement—essentially by residential consumers.
The current custom-design net-metering based mechanism is quite cumbersome, involves several steps of approval and application, which makes it difficult for residential households to install such a system. Hence a new type of standardized PV plant is proposed mainly targeting residential consumers in the form of do-it-yourself kit named as “PV-Port & Store”. The PV Port & Store system has been successfully prototyped in Germany and is currently in the upscaling stage in India where it will be a state-wide standard and subsidized product for the residential market.
