NEW DELHI — India’s rooftop solar expansion is undergoing a dramatic geographic shift, with smaller towns and rural areas now outpacing major cities in adoption rates, driven by government incentives and a $890 million World Bank loan to accelerate installations under the PM Surya Ghar programme. The trend marks a significant departure from earlier patterns, where metro areas dominated solar uptake, and underscores the growing role of tier-2 and tier-3 cities in India’s renewable energy transition.
What Happened
Data from the Ministry of New and Renewable Energy (MNRE) reveals that nearly 60% of new rooftop solar connections in the first quarter of 2026 were registered in towns with populations under 500,000, a stark contrast to 2023, when metro areas accounted for 70% of installations. This reversal coincides with the launch of PM Surya Ghar: Muft Bijli Yojana, a flagship scheme offering subsidies of up to 60% for residential solar systems and zero-interest loans for low-income households.
The World Bank’s $890 million (₹7,120 crore) financing, approved on June 12, 2026, is expected to support the installation of rooftop solar systems in 10 million households over the next three years, with a deliberate focus on smaller cities and rural regions. The funds will be disbursed through the Indian Renewable Energy Development Agency (IREDA) and state-level distribution companies (discoms) to reduce upfront costs for consumers.
Despite the programme’s ambitious target of covering 300 million eligible homes, only 4 million rooftop solar systems had been installed nationwide as of March 2026, according to MNRE records. Industry analysts attribute the slower uptake in metros to high property prices, complex approval processes, and limited roof space in multi-story buildings. In contrast, smaller towns benefit from lower installation costs, simpler regulatory pathways, and greater availability of individual rooftops.
Why It Matters
The shift in rooftop solar adoption has far-reaching implications for India’s energy security, economic development, and climate goals. With the country aiming to achieve 500 gigawatts (GW) of non-fossil fuel capacity by 2030, rooftop solar is a critical component of its renewable energy strategy. The World Bank’s financing could help bridge the gap between India’s solar potential and its current installed capacity, which remains heavily concentrated in large-scale solar parks rather than decentralized rooftop systems.
For smaller towns, the solar boom presents an opportunity to reduce electricity costs, improve grid stability, and create local jobs in installation and maintenance. In Uttar Pradesh’s Bareilly district, for example, rooftop solar capacity grew by 180% year-on-year in 2025, compared to a 30% increase in Mumbai, according to state energy department data. Similar trends have been observed in Gujarat’s Morbi, Rajasthan’s Alwar, and Tamil Nadu’s Tirunelveli, where local administrations have streamlined permitting and partnered with non-banking financial companies (NBFCs) to offer tailored loan products.
The World Bank loan includes a $200 million component for technical assistance, aimed at improving grid integration and training local installers. “Smaller towns often lack the skilled workforce needed for solar deployment,” a World Bank spokesperson stated. “This funding will help build capacity at the district level, ensuring that the benefits of rooftop solar reach beyond urban centers.”
Background and Context
India’s rooftop solar sector has long been hampered by structural challenges, including high upfront costs, regulatory bottlenecks, and limited consumer awareness. While the government has set a target of 40 GW of rooftop solar capacity by 2026, only about 10 GW had been installed as of early 2026, according to MNRE data. The PM Surya Ghar programme, launched in February 2024, seeks to address these barriers by offering direct subsidies, low-interest loans, and simplified application processes.
The programme’s focus on smaller towns aligns with broader government efforts to decentralize renewable energy adoption. In metro areas, high population density and vertical housing models limit the feasibility of rooftop solar, whereas smaller towns and rural areas offer more individual rooftops and lower land costs. Additionally, state-level policies play a crucial role in shaping adoption rates. Gujarat and Karnataka, for instance, offer additional subsidies and net metering incentives, while states like Bihar and Jharkhand have lagged due to bureaucratic delays.
Competing Claims and Uncertainty
While the shift toward smaller towns is promising, several challenges remain. One key concern is the reliability of grid infrastructure in rural and semi-urban areas, where frequent power outages could undermine the effectiveness of rooftop solar systems. Industry experts warn that without adequate grid modernization, excess solar energy generated during peak hours may go to waste, reducing the financial viability of installations.
Another point of contention is the uneven distribution of subsidies. While the central government provides up to 60% subsidy for residential systems, state-level variations in additional incentives could create disparities in adoption rates. For example, Gujarat offers an extra 20% subsidy for systems under 3 kW, while other states provide no additional support. This patchwork of policies could lead to a two-speed solar market, where wealthier states with proactive policies outpace others.
There are also questions about the long-term sustainability of the PM Surya Ghar programme. With only 4 million installations completed against a target of 300 million eligible homes, critics argue that the scheme’s success hinges on addressing last-mile challenges, such as awareness campaigns in regional languages and simplifying subsidy disbursement processes. Some industry stakeholders have called for greater private sector involvement to accelerate installations, while others emphasize the need for stronger enforcement of net metering policies to ensure consumers receive fair compensation for excess energy fed back into the grid.
What to Watch Next
1. State-Level Policy Divergence: The coming months will reveal which states are best positioned to capitalize on the World Bank funding. States with proactive policies, such as Gujarat, Karnataka, and Tamil Nadu, are likely to see faster adoption, while laggards like Bihar and Jharkhand may struggle to attract private investment.
2. Grid Modernization Efforts: The effectiveness of rooftop solar in smaller towns will depend on improvements in grid infrastructure. The government’s Revised Distribution Sector Scheme (RDSS), which aims to reduce aggregate technical and commercial (AT&C) losses, will be critical in ensuring that solar energy can be efficiently integrated into the grid.
3. Private Sector Participation: The role of NBFCs and solar financing companies will be crucial in expanding access to low-interest loans. Companies like Tata Capital, Bajaj Finance, and specialized solar lenders are expected to play a larger role in tier-2 and tier-3 markets.
4. Consumer Awareness Campaigns: The success of the PM Surya Ghar programme will hinge on outreach efforts in regional languages. The government has announced plans to launch awareness drives through local media, community organizations, and discoms, but their effectiveness remains to be seen.
5. Impact on Discoms: State-owned discoms, which have historically resisted rooftop solar due to revenue losses from reduced electricity sales, may face pressure to adapt. The World Bank’s technical assistance component could help discoms develop business models that accommodate decentralized solar generation.
Conclusion
India’s rooftop solar boom is no longer confined to its largest cities. The shift toward smaller towns and rural areas, accelerated by government incentives and World Bank financing, reflects both the structural advantages of these regions and the persistent barriers in metro areas. While the trend is encouraging, the long-term success of the PM Surya Ghar programme will depend on addressing last-mile challenges, including grid reliability, subsidy disbursement, and consumer awareness.
With 300 million eligible households, the programme has the potential to reshape India’s energy landscape, but its impact will be uneven without targeted interventions in underserved regions. As states compete to attract private investment and consumers weigh the financial benefits of solar adoption, the coming years will be critical in determining whether India can meet its ambitious renewable energy targets.
