India's PM Surya Ghar Muft Bijli Yojana has accelerated residential rooftop solar adoption, but the pace of roof top installations vary significantly across states despite a uniform central subsidy of up to Rs 78,000 per household. By March 2026, the scheme had supported rooftop solar installations across 26.21 lakh households, adding 9.56 GW of capacity. While the financial assistance remains the same across the country, adoption has increasingly been shaped by how effectively states facilitate and thus implement the scheme. Faster approvals, responsive DISCOMs, experienced and capable roof top installer ecosystems plus higher consumer awareness have enabled some states to move ahead more quickly than others.
The disparity is also reflected in the latest installation trends. According to JMK Research & Analytics, India installed 960.88 MW of residential rooftop solar capacity under the PM Surya Ghar Muft Bijli Yojana during June 2026, taking cumulative installations under the scheme to 44.88 lakh households. Uttar Pradesh led the country with 186.79 MW of residential rooftop solar capacity installed during the month, followed by Gujarat (124.37 MW) and Maharashtra (121.78 MW), highlighting how a handful of states continue to account for a significant share of new additions despite a common central subsidy.
Implementation Has Emerged As the Key Differentiator
States such as Gujarat, Maharashtra and Kerala entered the scheme with relatively mature rooftop solar ecosystems, allowing them to scale installations faster once the national programme was launched. Existing installer networks, streamlined utility processes and greater consumer familiarity with rooftop solar helped these states build on their early lead. In contrast, states where approval timelines remain longer, installer networks are still evolving and consumer awareness is relatively lower have witnessed slower adoption. Additional state-level incentives, stronger vendor ecosystems and smoother electricity utility approval processes have further strengthened implementation in several leading states.
These differences indicate that execution on the ground, rather than the subsidy itself, is increasingly determining the pace of rooftop solar adoption. "The subsidy is uniform, but the delivery machinery is not. What the state-wise numbers really measure is execution capacity, not solar potential," said Karthik Raju, Executive Director, Atria Renewable.
Faster DISCOM Processes Can Help Quicker Adoption
The speed of approvals has emerged as one of the biggest determinants of installation timelines. Faster feasibility clearances, inspections, net-metering approvals and commissioning allow rooftop systems to become operational sooner, while delays at any stage can significantly extend project completion. Alongside faster approvals, easier access to financing, digital application platforms, direct benefit transfers, higher retail electricity tariffs and greater consumer awareness have improved both the economics and ease of adopting rooftop solar for households. States that have combined these measures with efficient implementation have generally witnessed stronger adoption.
"A consumer who has applied, found an installer, and arranged financing still cannot go live without net metering approval from the DISCOM. Where that step is slow or unpredictable, it creates frustration at the very end of a journey the consumer has already committed to," said Mayank Garg, CEO, Aroma Solar. Administrative Delays Continue to Be the Biggest Challenge
Approval processes, inspections and net-metering continue to remain the principal sources of delay in many states. Financing constraints persist for households unable to meet the remaining project cost after subsidy support, while installer availability continues to vary across regions. In certain locations, local grid constraints also affect the pace of new rooftop solar connections. Many of these bottlenecks have gradually eased through digitalisation, time-bound approvals in several states and the expansion of installer networks. However, the implementation of domestic content requirements from June 2026 has also increased the importance of ensuring adequate availability of compliant solar cells and modules as installations continue to scale. "Most bottlenecks are administrative, such as delays in approvals, inspections and net-metering. Financing and installer availability also play a role," said Harshit Bansal, Director, Bansal Sunvolt Pvt. Ltd.
Best Practices Can Be Replicated Across States
Leading states have demonstrated that faster online approvals, efficient DISCOM processes, wider networks of trained installers and stronger coordination between electricity utilities and vendors can significantly improve rooftop solar adoption. Simplified customer journeys, sustained awareness campaigns, timely subsidy disbursals and innovative financing models have also helped build consumer confidence and accelerate installations. Several of these implementation measures can be replicated across by the slower-moving states without requiring significant policy changes, helping create a more consistent experience for consumers across the country. "Better coordination between electricity companies, vendors and consumers, along with faster approvals and stronger implementation systems, has enabled some states to move much faster," said Zhang Zhijun, India Regional Director at INVT.
Closing the Gap Will Be Critical to Meeting Targets
The PM Surya Ghar scheme targets rooftop solar installations across one crore households by March 2027. While the programme has gathered momentum, achieving that goal will require faster implementation in states that currently trail the national leaders. Greater standardisation of approval processes, stronger coordination between implementing agencies, expanded financing options and continued consumer awareness are expected to play an important role in narrowing regional disparities as installations continue to scale. "Variations across states are common during the early stages of any large-scale national programme. As awareness increases, installer networks expand, financing becomes more accessible and technology continues to become more affordable, we expect adoption to accelerate across more regions," said Ankit Patidar, Director & Chief Marketing Officer, Shakti Group.
As rooftop solar enters its next phase of growth, the emphasis is expected to shift from expanding financial incentives to improving execution. Standardised approvals, stronger DISCOM performance, wider installer networks and better coordination between the Centre and states will be critical to ensuring rooftop solar adoption becomes more evenly distributed and that the PM Surya Ghar Muft Bijli Yojana remains on track to achieve its target of one crore household installations by March 2027. |
