Market Segmentation Analysis:
By Capacity
The 50 kW to 1 MW segment dominated the rooftop solar EPC market with a 42% share in 2024. This segment’s dominance is driven by large-scale installations across commercial and industrial facilities aiming to offset high energy costs. Businesses adopt systems in this range to achieve significant reductions in grid dependency and improve long-term energy security. The growing preference for medium to large-capacity systems among manufacturing units and logistics centers enhances market growth, supported by favorable net-metering policies and declining module prices that make larger installations financially viable.
- For instance, Amplus Solar built a 4 MW rooftop at Yamaha’s Greater Noida plant, then added a further 2 MW plus a 100 kWp carport at the same facility.
By Application
The commercial and industrial segment held the largest share of 61% in 2024, supported by rapid adoption across corporate campuses, warehouses, and retail chains. Companies are investing in rooftop solar to meet sustainability goals and reduce operational expenses. The segment’s expansion is fueled by government incentives, corporate ESG commitments, and increased availability of third-party financing models. Industrial users, in particular, prefer solar EPC solutions due to predictable project timelines, turnkey service delivery, and improved returns from self-consumption and energy trading opportunities.
- For instance, Prologis announced in December 2023 that it had crossed the 500 MW threshold for its global rooftop solar portfolio
Key Growth Drivers
Rising Demand for Clean and Cost-Effective Energy
The growing shift toward renewable energy is driving strong demand for rooftop solar EPC projects. Businesses and households seek cost-effective and sustainable power alternatives. Falling solar panel prices and improved financing models make installations more accessible. Long-term savings on electricity bills and reduced emissions further enhance adoption. This growing interest supports the global transition toward decentralized clean energy generation and increases investments in rooftop solar capacity.
- For instance, Sunrun installed 242.4 MW of solar and 392 MWh of storage in Q4 2024, reflecting strong household adoption of distributed energy.
Government Incentives and Policy Support
Supportive government policies, including subsidies, tax rebates, and net-metering schemes, are accelerating rooftop solar EPC growth. Regulatory frameworks in major markets such as India, China, and the U.S. encourage both residential and commercial installations. Streamlined project approvals and state-backed incentives enhance the profitability of EPC projects. Renewable purchase obligations and public investments provide additional momentum. These policy measures ensure long-term stability and strengthen investor confidence in the rooftop solar EPC sector.
- For instance, a July 4, 2025, press release from the parent company, Tata Power, mentions that its solar arm has reached a portfolio of 3.4 GW of total installed capacity, exceeding 2 lakh rooftop solar installations.
Corporate Sustainability and ESG Commitments
Corporations are increasingly investing in rooftop solar to meet sustainability and decarbonization targets. The rising focus on achieving net-zero emissions has driven industries to adopt on-site renewable energy systems. EPC providers benefit from corporate ESG mandates that prioritize clean energy procurement. This shift enhances brand value, improves energy security, and reduces long-term operational costs. As a result, corporate adoption continues to expand across manufacturing, retail, and logistics sectors.
Key Trends & Opportunities
Advancement in Smart Monitoring and Digital EPC Solutions
Technological innovation is transforming EPC operations through smart monitoring and digital project management tools. AI-based analytics, IoT sensors, and predictive maintenance platforms enable efficient performance tracking. These tools improve energy output, reduce downtime, and enhance asset optimization. EPC firms integrating such technologies can deliver high-value turnkey projects. This digital transformation supports cost efficiency and positions tech-driven EPC players as key beneficiaries in future solar infrastructure development.
- For instance, As of the end of the second quarter of 2025, Enphase reported that it had shipped approximately 83.1 million microinverters and deployed more than 4.9 million Enphase-based systems globally.
Growth of Battery Storage Integration
The integration of battery storage with rooftop solar systems is creating major opportunities for EPC firms. Businesses and households are adopting hybrid systems to store excess energy and ensure continuous power supply. Falling battery prices and advancements in lithium-ion technology drive adoption. EPC contractors offering combined solar-plus-storage projects gain competitive advantage. These systems improve grid resilience, enable peak-load management, and expand opportunities for distributed energy generation.
- For instance, Sungrow signed distribution deals for 1.7 GWh of C&I energy-storage systems in Australia, enabling large solar-plus-storage rollouts over three years.
Key Challenges
High Upfront Costs and Financing Barriers
The high initial cost of rooftop solar systems continues to limit adoption, particularly among small consumers. Access to affordable financing and awareness of financial incentives remain limited in developing regions. Many households and SMEs face difficulties obtaining loans for installations. EPC firms must collaborate with financial institutions to promote leasing and low-cost financing models. Addressing these financial barriers is crucial to accelerate adoption and sustain long-term market growth.
Grid Integration and Policy Uncertainty
Regulatory inconsistency and grid integration issues pose significant challenges to market expansion. In several regions, interconnection delays, voltage fluctuations, and capacity restrictions hinder smooth rooftop solar deployment. Unclear or changing net-metering regulations further discourage new adopters. Harmonized grid standards and predictable policies are vital for stable sector growth. Collaboration among EPC firms, utilities, and policymakers will be essential to overcome these integration challenges and ensure scalability.
