Note: Potential assessment based on the India Residential Energy Survey (IRES) dataset. The estimated RTS potentials are without any capital subsidy.• Unlocking the technical potential in the residential segment requires introducing innovative business models to utilise excess roof space.• This can play a significant role in India’s energy transition and contribute towards its renewable energy (RE) target of 500 GW of installed capacity by 2030. 637 GW~102 GW ~11 GW All suitable rooftops are entirely covered with solar.118 GW Restricting rooftop solar (RTS) size to meet households’ electricity demand.Estimation based on economic viability (Net present value > 0).Based on consumer willingness to pay and payback in a five year period.IRES survey 2020 coverage•21 states covering 97% of the population•14,850 households with eight households from each village/ward6|Decoding rooftop solar potential at the national and state levelsSource: Authors’ analysis.Note: 1.
