The Sustainable Rooftop Implementation for Solar Transfiguration of India (SRISTI) scheme was announced in early 2019. It was expected to rejuvenate the roof top photovoltaic (RTPV) sector, which by then had achieved only ~1.2 GW of the 40 GW target for 2021–22. SRISTI targeted the underserved residential category by offering attractive capital subsidies of up to 40% for 1–3 kW systems and 20% for 3–10 kW ones. The scheme also had a subsidy component of 20% for large apartment complexes and group housing societies.
