Market Overview

The India Solar Rooftop Market is entering a high-growth phase as households, commercial establishments, industries, and institutions increasingly adopt distributed solar power to reduce electricity costs and improve energy security. The market is projected to grow at a CAGR of 15.19% during 2026–2034, reaching approximately USD 7.14 billion by 2034. Based on the forecast trajectory, the market represents an estimated value of around USD 2.3 billion in 2026. The rapid expansion is being supported by India's renewable-energy targets, government subsidies, declining photovoltaic module prices, improved financing availability, growing electricity demand, and increasing awareness of decentralized power generation.

One of the most important growth catalysts is the PM Surya Ghar: Muft Bijli Yojana, which has a total outlay of approximately ₹75,021 crore and targets rooftop solar installations for one crore households. The scheme provides central financial assistance of up to ₹78,000 for eligible residential systems and facilitates low-cost financing. In March 2025, the government reported that more than 10 lakh rooftop solar installations had already been completed, with more than 3 GW of rooftop capacity facilitated under the programme. The government has targeted an additional 27 GW of rooftop capacity by March 2027.

The market is also benefiting from domestic manufacturing policies, the Approved List of Models and Manufacturers framework, growing production of solar cells and modules, and expansion of inverter and battery-storage capabilities. Falling module costs and improvements in high-efficiency photovoltaic technologies are making rooftop installations increasingly attractive. Opportunities are emerging in integrated solar-plus-storage systems, smart energy management, digital monitoring, residential financing, community solar, commercial and industrial rooftop projects, and energy-as-a-service models.

U.S. Solar Rooftop Market Trends and Investment in 2025

The U.S. rooftop solar market experienced a mixed but significant year in 2025. According to the Solar Energy Industries Association, the U.S. installed approximately 43.1 GWdc of solar capacity in 2025, while residential solar installations reached about 4.65 GWdc, down approximately 2% from 2024. Policy uncertainty surrounding the expiration of the Section 25D residential clean-energy tax credit accelerated customer and installer activity toward the end of 2025. Commercial solar increased approximately 6% year over year, while utility-scale solar remained the largest installation segment. The passage of the One Big Beautiful Bill Act in July 2025 also changed the investment environment by accelerating the phaseout of several clean-energy incentives. At the same time, domestic solar manufacturing continued to expand, with new U.S. cell and wafer manufacturing capacity coming online. These developments demonstrate both the opportunities and policy risks facing rooftop solar markets globally.

Market Segmentation: Leading Segments

By End User, the residential segment represents the most important growth opportunity in India's rooftop solar market. Government incentives are strongly focused on household installations, particularly through PM Surya Ghar, which aims to bring rooftop solar to one crore households. By January 2025, the programme had already benefited approximately 8.46 lakh households, with monthly installation rates reaching around 70,000—approximately ten times the pre-scheme level.

By Connectivity, grid-connected rooftop solar systems represent the leading segment, supported by India's extensive electricity-distribution infrastructure and net-metering mechanisms. Grid-connected systems enable consumers to use solar electricity directly while exporting surplus generation to the grid where applicable.

By Capacity, small residential systems are expected to remain particularly significant, supported by subsidies for systems up to 3 kW. This segment directly benefits from the structure of PM Surya Ghar, which provides higher financial assistance for the first 2 kW and additional support for capacity between 2 and 3 kW.

Competitive Landscape

The Indian rooftop solar industry is highly competitive, with established power companies, solar manufacturers, EPC providers, and specialized rooftop installers expanding their presence.

Tata Power Renewable Energy/Tata Power Solar is one of the strongest players in India's rooftop segment. In March 2025, Tata Power reported more than 150,000 rooftop installations and approximately 3 GW of cumulative rooftop capacity across India. In July 2025, it reported 45,589 rooftop installations during Q1 FY26, taking cumulative installations above 204,000 and total capacity beyond 3.4 GW. Its strategy combines domestic manufacturing, financing partnerships, long-term module warranties, retail distribution, and government-scheme participation.

Adani Solar benefits from vertical integration across solar manufacturing and renewable-energy development. Its expansion of domestic photovoltaic manufacturing supports India's localization objectives and reduces dependence on imported components, creating opportunities for more competitive solar solutions.

Waaree Energies is another major Indian solar manufacturer with significant module-production capabilities and a growing presence across solar projects. In FY2025, Waaree was among India's leading module suppliers, alongside Jinko and LONGi. Its manufacturing scale and expansion into higher-efficiency modules can support rooftop solar deployment.

Mahindra Solarize has developed a significant presence in distributed and rooftop solar, particularly through residential and commercial installation solutions. Industry research identified Mahindra Solarize among the leading companies deploying rooftop/onsite solar projects in FY2025.

Orb Energy is another important distributed-solar participant, particularly in commercial and industrial rooftop installations. It was also identified among the leading rooftop/onsite solar players in India during FY2025.

The broader competitive environment is increasingly shaped by battery integration, high-efficiency modules, digital monitoring platforms, smart inverters, flexible financing, and turnkey EPC services.

Regional Analysis

Although India remains the central market covered by this report, international developments provide important context for the country's rooftop solar opportunity.

United States: The U.S. remains a major solar market, with residential installations continuing despite policy uncertainty. Solar accounted for 54% of new U.S. electricity-generating capacity in 2025.

China: China remains the world's largest solar manufacturing and deployment ecosystem. However, market-based pricing reforms introduced in 2025 contributed to a significant decline in quarterly PV installations during Q3, highlighting the growing importance of market design and grid integration.

Germany: Germany's rooftop solar growth is supported by its energy-transition policies, high electricity costs, distributed-generation model, and increasing integration of battery storage.

United Kingdom: The UK rooftop market continues to benefit from decarbonization policies, household energy-cost concerns, and increasing consumer interest in solar-plus-storage solutions.

France: France is expanding distributed solar as part of its renewable-energy transition, with rooftop installations supported by self-consumption and renewable-energy policies.

Japan: Limited land availability, high energy-security requirements, and continued adoption of distributed generation make rooftop solar particularly relevant to Japan.

Conclusion

The India Solar Rooftop Market is positioned for strong long-term expansion, with the market projected to reach USD 7.14 billion by 2034 at a 15.19% CAGR. In my view, the most influential growth factor will be the combination of government financial support and easier consumer financing, particularly under PM Surya Ghar. The programme has already demonstrated that subsidies, digital application platforms, financing, and simplified installation can substantially increase household adoption.

The next major opportunity will be the integration of rooftop solar with battery storage, smart inverters, AI-based energy management, and electric-vehicle charging. As solar penetration increases, storage and intelligent grid management will become increasingly important. Companies capable of offering complete solutions rather than standalone panels are likely to gain a competitive advantage. Continued domestic manufacturing, falling technology costs, expansion into underserved households, and innovative financing models should further accelerate India's transition toward decentralized and cleaner electricity generation.
