India has launched a ₹2.3-crore innovation challenge to drive rooftop solar adoption through startup-led innovation. The Ministry of New and Renewable Energy (MNRE) unveiled the initiative on June 21, 2025, during the National Conference on Skill Development for the Renewable Energy Workforce, held at Atal Akshay Urja Bhawan in New Delhi. The government, in collaboration with the National Institute of Solar Energy (NISE) and StartUp India, created this program to accelerate the deployment of rooftop and decentralized renewable energy solutions across the country.
This move aligns with India’s broader climate goals and addresses the urgent need for affordable, inclusive, and sustainable rooftop solar systems that benefit both urban and rural populations.
🔍 Objective: Innovation for Inclusive, Scalable Solar
The government structured the challenge around four core pillars—Affordability, Resilience, Inclusivity, and Environmental Sustainability. Each pillar aims to solve a key barrier in rooftop solar adoption and energize the ecosystem with practical, scalable innovation.
- Affordability
Startups must develop low-cost solar systems and tools that reduce upfront capital expenses. The government wants to enable households, small businesses, and communities to adopt solar without facing financial burdens. Solutions may include plug-and-play solar kits, peer-to-peer lending models, and AI-driven demand forecasting tools for efficient energy use. - Resilience
Innovators should focus on improving solar systems’ capacity to withstand extreme weather, grid instability, and cybersecurity threats. The program encourages startups to create technologies for remote monitoring, smart inverters, and disaster-resilient mounting structures. - Inclusivity
The government wants startups to bridge the gap between privileged and underserved communities. Innovators can design solutions for shared solar systems, solar for rental properties, and financing models for low-income groups. The goal is to ensure everyone—regardless of geography or income—can access solar energy. - Environmental Sustainability
The scheme challenges startups to develop environmentally conscious designs such as recyclable solar panels, non-toxic materials, land-neutral mounting options, and hybrid renewable systems that combine solar with wind or bioenergy.
💰 Funding Structure and Non-Monetary Benefits
The government allocated the ₹2.3 crore as follows:
- ₹1 crore for the first prize
- ₹50 lakh for the second prize
- ₹30 lakh for the third prize
- ₹5 lakh each for ten promising ideas
Beyond the monetary incentives, the government also committed to supporting winners through incubation, pilot deployments, and mentorship. The selected startups will receive direct guidance from industry leaders, access to renewable energy testbeds, and visibility at national energy platforms.
Startups can submit proposals via the StartUp India portal. The challenge remains open until August 20, 2025, and the winners will be announced on September 10, 2025.
📈 India’s Rooftop Solar Landscape: Growth, Challenges, and Potential
India’s rooftop solar segment has grown steadily in the last few years, but adoption remains below its full potential. As of April 2025, India had installed around 108 GW of total solar capacity. Rooftop installations contributed nearly 12% of this figure, with much of the growth coming from Gujarat, Maharashtra, Tamil Nadu, and Delhi.
The country’s flagship rooftop solar initiative—PM Surya Ghar Muft Bijli Yojana—aims to provide free electricity to 1 crore households. Gujarat leads the way, with over 3.3 lakh rooftop systems generating more than 1,200 MW. The state issued over ₹2,300 crore in subsidies and reported significant carbon emission reductions.
Other states such as Chandigarh have also made strong progress. The Chandigarh Renewable Energy and Science & Technology Promotion Society (CREST) installed 20 MW of solar capacity on government buildings and now actively targets residential rooftops. CREST offers flexible subsidy options and power purchase models, ensuring middle-class households can benefit without significant capital investment.
💼 Market Implications and Startup Opportunities
Startups entering this space will gain access to a high-growth, policy-backed market. India aims to install over 280 GW of solar energy by 2030, with rooftop solar playing a vital role. The government expects decentralized energy solutions to deliver localized energy security, reduce reliance on fossil fuels, and contribute significantly to job creation.
Startups can target several pain points:
- Hardware: Designing lightweight, low-cost panels and mounting equipment
- Software: Creating AI/ML-based energy management systems
- Finance: Developing solar lending tools and pay-as-you-go apps
- Installation: Offering one-stop installation and maintenance services for tier-2 and tier-3 cities
By solving these gaps, startups can capture both social impact and profitability.
🛠️ Role of Ecosystem Players
The challenge brings together multiple stakeholders—government agencies, private investors, research institutions, and utilities.
- Government bodies offer policy support, funding, and pilot opportunities.
- Venture capitalists can identify and invest in high-potential cleantech startups early in their growth cycle.
- Research institutes such as NISE and IITs can provide technical validation and academic partnerships.
- Utilities and DISCOMs can partner with startups to deploy innovations at scale, reducing their losses and meeting renewable purchase obligations.
This synergy enables a fast-track deployment model where innovations move from lab to field with efficiency and speed.
📉 Why Rooftop Solar Needs a Boost
Despite its benefits, rooftop solar adoption in India faces challenges:
- High upfront costs remain a barrier, especially in low-income areas.
- Lack of awareness and misinformation hinder public interest.
- Installation processes often involve complex paperwork and delayed subsidies.
- DISCOMs hesitate to promote rooftop solar due to fear of revenue loss.
This startup challenge directly addresses these issues. The government aims to bring agile, tech-driven solutions into a traditionally slow-moving sector.
📅 Short-Term and Long-Term Impact
Short-Term (3–6 Months)
The startup community will respond with diverse innovations. NISE will evaluate solutions based on practicality, scalability, and impact. The government will shortlist startups and initiate pilot deployments in select urban and rural regions.
Mid-Term (6–24 Months)
Successful ideas will move to scale-up mode. The government may introduce additional funding or merge winning ideas with the PM Surya Ghar scheme. Rooftop installations will increase in underserved districts, and awareness campaigns will accompany technology rollouts.
Long-Term (Post 2027)
India’s rooftop solar network will reach maturity with widespread adoption across housing societies, rural households, and commercial buildings. The decentralized model will reduce stress on transmission infrastructure, increase grid resilience, and contribute significantly to India’s net-zero targets.
🔚 Conclusion: Lighting Up India, One Rooftop at a Time
The ₹2.3-crore startup innovation challenge represents more than financial aid—it symbolizes India’s shift toward inclusive, tech-powered energy access. By inviting startups to tackle real-world issues in rooftop solar, the government creates opportunities for sustainable economic development and environmental responsibility.
The success of this initiative depends not only on innovation but also on collaboration. With state governments, private sector players, and civil society all working in tandem, India stands poised to transform its rooftops into engines of clean energy and economic empowerment.
This scheme is not just about energy; it’s about building a greener, smarter, and more equitable future.
