Smaller cities like Lucknow and Surat are now outpacing major metros in rooftop solar adoption under the Pradhan Mantri Surya Ghar scheme. With over 3.6 million installations completed, the government has already distributed ₹25,000 crore in subsidies to support this transition.
India’s rooftop solar energy landscape is witnessing a structural shift as smaller cities take the lead in adoption. Recent data indicates that districts including Lucknow, Nagpur, Surat, Varanasi, and Ernakulam have emerged as the fastest-growing regions for solar installations. Interestingly, India’s largest metropolitan hubs, such as Delhi, Mumbai, and Bengaluru, are currently not represented among the top 100 performing districts in this segment.
Impact of the Pradhan Mantri Surya Ghar Yojana
The central government’s 'Pradhan Mantri Surya Ghar: Muft Bijli Yojana,' introduced in February 2024, has acted as the primary catalyst for this expansion. The scheme is designed to provide up to 300 units of free electricity per month to eligible households. As of mid-2026, the program has successfully facilitated the deployment of 3.63 million rooftop systems, benefiting more than 4.41 million households. The government’s commitment to this initiative is reflected in its financial activity, with over ₹25,000 crore in subsidies already disbursed out of the total allocated budget of ₹75,021 crore.
Regional Leaders and Implementation Success
States like Maharashtra, Gujarat, Uttar Pradesh, Rajasthan, Kerala, and Assam are reporting significant growth in installation numbers. This success is largely attributed to localized awareness campaigns and the establishment of specialized teams at the district and distribution company levels. By streamlining the application process and providing clear information, these regions have achieved a consistent installation rate of approximately three lakh units per month. For investors in the power and renewable sector, this rapid scale-up suggests a widening market for domestic solar component manufacturers and installation service providers.
Future Expansion Models for Urban Reach
To maintain this growth, the government is moving beyond individual household installations. Strategies include targeting group housing societies, where a single large-scale installation can serve multiple apartments. Additionally, the adoption of the Utility-Led Aggregation model aims to bring solar energy to low-income families who previously faced financial or building-related hurdles. This model is set to target an additional 30 lakh households.
While the scheme is driving significant volume, the primary monitorables for the sector remain the sustained availability of high-quality, domestically manufactured solar modules and the speed at which distribution companies can process grid connectivity approvals for these new systems. Investors tracking this space will continue to watch for updates on the utilization of the remaining subsidy funds and the long-term impact on residential power demand patterns.
