Odisha's rooftop solar revolution is well underway, but its ability to sustain momentum and evolve into a national model will ultimately depend on addressing concerns over quality, transparency, accountability and consumer trust, says Priyabrat Biswal

 

Odisha's rooftop solar revolution is being celebrated as one of the country's most remarkable clean energy success stories. From securing top honours at the PM Surya Ghar Excellence Awards to crossing the milestone of one lakh rooftop solar installations, the state has emerged as a frontrunner in India's ambitious push towards decentralized renewable energy. Yet, behind the impressive numbers and national recognition lies a more complex story — one that combines rapid growth with mounting concerns over quality, accountability, consumer protection and transparency. As Odisha marches towards its ambitious target of three lakh rooftop solar installations by March 31, 2027, the state finds itself at a critical juncture where the sustainability of success may depend as much on governance and quality assurance as on installation numbers.

The PM Surya Ghar: Muft Bijli Yojana has transformed India's rooftop solar landscape at an unprecedented pace. As of June 3, 2026, more than 70.59 lakh applications had been received across the country, resulting in over 33.57 lakh rooftop solar installations and a cumulative installed capacity exceeding 12,092 MW. Odisha has emerged as one of the standout performers under the scheme, registering 2.43 lakh applications and completing 1,01,056 rooftop solar installations with a cumulative capacity of 265.25 MW. The achievement is particularly significant considering that the state has successfully expanded rooftop solar adoption beyond major urban centres into several semi-urban and rural regions.

The state's performance has earned national recognition. Odisha recently swept the PM Surya Ghar Excellence Awards, securing first position in three major categories — Maximum Consumer Applications, Maximum Solar Installations and Maximum DISCOM Inspections — while also claiming third place nationally for Maximum Vendor Registrations. The awards reflect the scale of consumer participation and administrative effort that have gone into implementing the programme. For a state that only a few years ago was considered a relatively modest player in India's rooftop solar sector, the transformation has been remarkable.

Much of this success has been driven by the state's four power distribution companies. Among them, TPCODL has emerged as the clear leader, accounting for 33,941 rooftop solar installations from 83,038 applications and delivering 93.72 MW of installed capacity. Covering Bhubaneswar, Cuttack and surrounding urban centres, TPCODL has benefited from greater consumer awareness, stronger purchasing power and easier access to vendor networks. TPWODL has emerged as a strong performer in western Odisha, recording 29,563 installations and an installed capacity of 83.46 MW from nearly 59,500 applications. TPNODL has also delivered encouraging results, completing 26,324 installations with a capacity of 59.90 MW. TPSODL, however, appears to be lagging behind its counterparts, with 11,361 installations and 28.31 MW capacity despite receiving over 42,000 applications. The performance gap suggests that while consumer interest exists across all regions, the pace of conversion from application to installation remains uneven.

The district-wise distribution of rooftop solar systems reveals another interesting trend. Solar adoption in Odisha is heavily concentrated in a relatively small number of districts. The top ten districts alone account for 62,638 installations, representing nearly 62 per cent of all rooftop solar systems installed in the state. Khordha leads the list with 10,350 installations, followed by Balasore with 9,571 and Cuttack with 8,103. Ganjam, Mayurbhanj, Sundargarh, Bargarh, Jajpur, Jagatsinghpur and Bolangir complete the top ten rankings. The concentration highlights the strong role played by urbanization, economic activity and consumer awareness in driving solar adoption. It also indicates that while rooftop solar has gained significant traction in some regions, the benefits have not been distributed evenly across the state.

The contrast becomes even more apparent when examining the least-performing districts. Kandhamal has recorded only 413 installations, while Malkangiri and Deogarh have achieved 482 and 512 installations respectively. The disparity between leading and lagging districts is striking. Khordha alone has installed nearly twenty-five times more rooftop solar systems than Kandhamal. Such gaps raise important questions about accessibility, awareness and infrastructure readiness in Odisha's tribal and geographically remote districts. If the state is to achieve an inclusive energy transition, greater focus will need to be placed on ensuring that these regions are not left behind in the solar revolution.

While Odisha's achievements are undoubtedly impressive, the road ahead presents a formidable challenge. With just over one lakh installations completed so far, the state still needs to add nearly two lakh more rooftop solar systems to achieve its target of three lakh installations by March 31, 2027. In practical terms, this means Odisha must almost triple its existing installation base within less than a year. Achieving such growth will require not only sustained consumer interest but also significant improvements in implementation efficiency, vendor performance and consumer confidence.

It is precisely on these issues that concerns are beginning to emerge. The rapid expansion of the programme has been accompanied by a sharp increase in the number of registered vendors. While the growth of the vendor ecosystem is essential for scaling up installations, questions are increasingly being raised about the quality of work being delivered on the ground. Consumers and industry observers alike have reported instances of substandard civil work, poor wiring practices, delays in project completion and inadequate after-sales support. There is a growing perception that while the focus remains heavily on achieving installation targets, quality assurance mechanisms have not evolved at the same pace.

One of the most significant concerns relates to accountability. Under the existing framework, consumers often find themselves dealing directly with vendors, particularly after subsidy disbursement. In cases where workmanship is poor or defects emerge, many consumers are unsure where responsibility ultimately lies. Questions are increasingly being asked about whether uniform standards exist for installation quality, whether material specifications are independently verified, and whether there is any systematic inspection process to ensure compliance before commissioning. Given that rooftop solar systems are expected to operate safely for decades, these concerns cannot be dismissed lightly. Poor-quality installations could potentially create long-term safety risks, including electrical faults, structural weaknesses and fire hazards.

Concerns over consumer grievance redressal are adding to the unease. During the course of this investigation, an aggrieved consumer shared details of an installation that was allegedly promised within two days but reportedly took over a month to become operational. According to the consumer, several components of the associated civil work remained incomplete and repeated requests for rectification yielded little response. The consumer further claimed that complaints lodged with the concerned authorities failed to result in timely corrective action. While individual cases may not necessarily represent the entire programme, such experiences highlight the importance of having robust grievance resolution mechanisms capable of responding quickly and effectively.

In an effort to better understand these concerns, detailed queries were sent on May 22, 2026 to Tata Power's Corporate Communication Department. The questions sought clarification on installation standards, material quality benchmarks, pricing regulations, inspection mechanisms, warranty accountability and electricity billing methodologies under the rooftop solar programme. Specific queries also sought to understand whether installation quality is independently verified, whether vendors operate under standardized guidelines, and how the much-publicized 25-year solar panel guarantee is enforced in cases of equipment failure. Additional questions focused on consumer billing, including how surplus electricity generation is adjusted and whether claims regarding "zero electricity bills" adequately account for fixed charges and electricity duty.

Despite the detailed communication, no response was received. A reminder sent on May 26, 2026 also remained unanswered. The absence of any official clarification has only intensified concerns regarding transparency and consumer awareness. In a programme of this scale and public significance, proactive communication is essential not only for addressing consumer doubts but also for maintaining trust in the system.

Another area where confusion persists is the availability of state government incentives. While awareness regarding Central Government subsidies has improved considerably, many consumers remain unclear about Odisha Government subsidy provisions, and application procedures. Potential beneficiaries often struggle to find clear information regarding available financial support, documentation requirements and timelines for subsidy disbursement. Improved public communication on these aspects could play a significant role in accelerating adoption, particularly in rural and lower-income households where affordability remains a major consideration.

The coming months may well determine the future trajectory of Odisha's rooftop solar programme. There is little doubt that the state has established itself as one of India's leading renewable energy success stories. The numbers are impressive, the national recognition is significant, and public interest remains strong. Yet the next phase of growth will require more than simply adding new installations. It will require building confidence that every installation meets acceptable quality standards, that grievances are resolved promptly, that vendors are held accountable, and that consumers are fully informed about both benefits and responsibilities.

As Odisha races towards its ambitious three-lakh-installation target, the challenge is no longer merely one of expansion. It is one of ensuring that growth is accompanied by quality, transparency and trust. The state's rooftop solar revolution has undoubtedly begun. Whether it can sustain its momentum and emerge as a truly model programme for the nation will depend on how effectively these emerging concerns are addressed. For now, Odisha's solar success story remains one of immense promise — but also one facing its most important test yet.
