Background and Context
The India rooftop solar market experienced a transformative year in 2025, recording a massive 123.3% growth to reach 7.1 GW of new capacity, up from 3.2 GW in 2024. This surge underscores the growing appetite for decentralized clean energy among commercial and industrial (C&I) consumers. As businesses seek to hedge against rising grid tariffs, the rooftop segment has become a critical pillar of India’s 2030 renewable energy targets.
Key Details
According to the Mercom India Solar Market Leaderboard 2026, five major players—Tata Power Solar, Roofsol Energy, Mahindra Solarize, Kalpa Power, and HARTEK—collectively captured 23.6% of the rooftop market. This competitive landscape is supported by a robust policy environment. Notably, the Rajasthan High Court recently issued a landmark ruling prohibiting the state government from retrospectively withdrawing electricity duty exemptions, reinforcing investor confidence in long-term policy certainty.
Project activity remains high, with the Solar Energy Corporation of India (SECI) seeking ₹6.6 billion in term loans for a 200 MW project in Dhar, Madhya Pradesh. Additionally, MAHAGENCO has initiated a tender for land leasing and grid connectivity services for 175 MW of solar capacity in Maharashtra. Private sector interest is equally strong, exemplified by Raviraj Corn Products commissioning a 2.63 MW solar installation in Solapur, projected to save the firm ₹28 million annually.
What This Means for EPCs and Developers
For EPC contractors, the rapid expansion of the rooftop sector necessitates a focus on operational efficiency and supply chain management. While MNRE officials have indicated that there are no immediate supply constraints for solar cells and modules, the scale of growth requires developers to secure reliable land parcels and grid connectivity early. The trend of large-scale C&I adoption, as seen in the Solapur project, highlights a lucrative niche for developers capable of delivering integrated ground-mounted and rooftop solutions.
What Happens Next
The industry is now looking toward sustained growth as the government continues to streamline land acquisition and right-of-way processes. With the formation of new joint ventures, such as the partnership between Adani Renewable Energy Middle East and Minerva Holding, the market is expected to see increased capital inflow. As India’s renewable energy sector continues to mature, the focus will shift from simple capacity addition to optimizing grid integration and ensuring long-term project viability through stable regulatory frameworks.
