The Government of India launched the PM Surya Ghar Muft Bijli Yojana to accelerate household rooftop solar adoption and reduce electricity expenditure. This study examines the key socio-economic and perceptual determinants influencing adoption intention among Indian households. Primary data were collected from 163 respondents using a structured questionnaire. Reliability and validity were assessed using Cronbach’s alpha, KMO and Bartlett’s tests. Descriptive statistics, correlation and multiple regression analyses were employed. The scale demonstrated excellent reliability (α = 0.95). Results indicate that cost saving belief, government subsidy awareness and environmental concern significantly influence adoption intention, explaining 79% of the variance. The findings confirm the effectiveness of financial incentives and awareness initiatives under the scheme and highlight strong youth-driven environmental consciousness. Policy implications for strengthening subsidy communication and targeted outreach are discussed.
