Mapping India’s residential rooftop solar potential: a bottom-up assessment using primary data

CEEW conducted a detailed assessment of the technical, economic, and market potential of deploying rooftop solar (RTS) in Indian households by adopting the bottom-up approach. i.e. starting at the household level. The study utilises the primary data collected in India Residential Energy Survey (IRES) of 14,850 households spanning across 21 states and 152 districts in 2020. The assessment further provides insights into the RTS potential of different states, the urban-rural split, and the potential for different system sizes. Rooftop solar provides an opportunity for households to contribute significantly to the ongoing energy transition by substituting their electricity consumption with solar. The true economic and market potential can be captured only by considering households’ economic strength and energy footprint.
