India’s rapid expansion of solar power capacity is central to achieving energy security, climate mitigation, and sustainable development goals. While national-level growth has been extensively documented, regional variations in deployment trajectories and policy effectiveness remain underexplored. This study presents a regionally disaggregated analysis of solar power development across Indian states between 2014 and 2025, examining spatial–temporal growth patterns, structural constraints, and policy implications. Using secondary data from national energy agencies, the study applies compound annual growth rate (CAGR) analysis, trend assessment, and policy mapping to evaluate state-wise and regional performance. During the study period, India’s cumulative installed solar capacity increased from less than 5 GW in 2014 to over 75 GW by 2025, corresponding to an average annual growth rate exceeding 30%. However, the results reveal substantial regional heterogeneity: western and southern states account for more than 60% of total installed capacity, with several states exhibiting CAGRs above 35%, while eastern and northeastern regions contribute less than 10%, reflecting slower adoption and infrastructural constraints. The observed disparities are strongly associated with differences in policy execution, grid readiness, land availability, and institutional capacity. The findings highlight the necessity of region-specific policy interventions, targeted financial mechanisms, and governance reforms to enable a more balanced and resilient solar energy transition. By providing a quantitative regional perspective, this study contributes actionable insights for national energy planning and subnational sustainability strategies
