India Solar Rooftop Market size was valued at USD 5.36 Billion in 2023 and the India Solar Rooftop Market revenue is expected to reach USD 6.17 Billion by 2030, at a CAGR of 15.19 % over the forecast period....
Market Overview
The India Solar Rooftop Market is witnessing unprecedented growth, fueled by a confluence of policy support, declining costs, increasing power demand, and the country's robust push toward renewable energy. As India charts a path toward becoming a net-zero carbon emitter by 2070, rooftop solar is emerging as a cornerstone in the country’s decentralized energy infrastructure.
According to recent market analyses, India’s rooftop solar capacity has grown by over 1.9 GW in the last year alone, with cumulative installed capacity now exceeding 11 GW as of Q1 2025. With ambitious government targets, strong investor interest, and increasing consumer adoption across residential, commercial, and industrial sectors, the solar rooftop market in India is poised for exponential growth in the next decade.
Government Initiatives and Policy Frameworks Fueling Market Expansion
A major driving force behind the surge in rooftop solar adoption is the Indian government's consistent push for renewable energy through robust policy interventions. The Ministry of New and Renewable Energy (MNRE) has introduced a slew of initiatives including the Grid Connected Rooftop Solar Programme Phase-II, which aims to install 40 GW of rooftop solar capacity across the country.
Under this program, substantial subsidies are offered to residential consumers—up to 40% for systems up to 3 kW and 20% for systems between 3 kW and 10 kW. Additionally, the Rooftop Solar Scheme allows discoms (distribution companies) to implement solar projects under a performance-based incentive mechanism, accelerating the pace of rooftop deployments.
Many states have also introduced their own policies and net metering regulations to incentivize rooftop solar installation. Gujarat, Maharashtra, Rajasthan, and Tamil Nadu lead the pack in terms of installed capacity, supported by proactive state-level schemes.

Growing Adoption Across Sectors
The rooftop solar segment in India is witnessing increased traction across residential, commercial, and industrial applications:
- Residential Segment: There has been a notable uptick in the adoption of solar rooftops by individual homeowners, housing societies, and gated communities. Easy financing options, rooftop leasing models, and government subsidies are enabling middle-class households to make the switch to clean energy.
- Commercial Sector: Businesses are turning to rooftop solar to mitigate rising power tariffs and reduce their carbon footprints. Shopping malls, office complexes, and educational institutions are integrating solar rooftops to achieve energy independence and earn favorable ESG ratings.
- Industrial Users: Industries are among the largest energy consumers in the country, and rooftop solar presents an opportunity to reduce electricity bills significantly. Companies in manufacturing, food processing, textiles, and pharmaceuticals are adopting solar rooftops to improve operational efficiency and sustainability.
Declining Costs and Advancements in Technology
One of the most compelling drivers of the India solar rooftop market is the sharp decline in the cost of solar photovoltaic (PV) systems. The cost of solar modules has dropped by over 80% in the last decade, making solar rooftop systems increasingly affordable for a broad spectrum of users.
Advancements in solar panel efficiency, inverter technology, battery storage solutions, and smart metering systems are enhancing the reliability and output of rooftop solar installations. Additionally, the proliferation of IoT-based energy management platforms is empowering consumers to monitor and optimize solar generation and energy consumption in real time.
Role of Discoms and Utility Partnerships
While rooftop solar enables energy self-reliance, the role of distribution companies (discoms) remains pivotal. Discoms serve as facilitators for grid integration, net metering approvals, and subsidy disbursals.
However, challenges such as delays in net metering approvals, operational inefficiencies, and resistance from discoms fearing revenue loss continue to be pain points. To counter this, new business models are emerging that foster collaboration between discoms and consumers—such as utility-led solar models, peer-to-peer energy trading, and virtual net metering.
Private Sector Participation and Investment Trends
The Indian rooftop solar market has attracted significant attention from private investors, EPC (Engineering, Procurement, and Construction) companies, and technology providers. Major players such as Tata Power Solar, Adani Solar, Azure Power, CleanMax, and Amplus Solar have established a strong presence in both B2C and B2B segments.
Private equity and venture capital firms are also increasingly backing solar rooftop start-ups, while international development agencies such as the World Bank and ADB are extending concessional financing to scale rooftop adoption. Moreover, innovative financing mechanisms such as solar loans, pay-as-you-go models, and green bonds are helping bridge the funding gap.

Challenges Hindering Market Potential
Despite the promising outlook, the India rooftop solar market faces several systemic challenges:
- Regulatory Uncertainty: Varying policies across states and frequent changes in net metering regulations create ambiguity for developers and consumers.
- Lack of Awareness: In many regions, especially rural areas, the benefits of rooftop solar are not well understood by potential users.
- Financing Barriers: High upfront costs and lack of credit access prevent many households and small businesses from investing in rooftop systems.
- Space Constraints: In dense urban environments, inadequate rooftop space or shading from nearby structures affects solar generation potential.
- Grid Integration: Ensuring seamless grid stability and voltage management with increasing distributed generation remains a technical hurdle.
Addressing these bottlenecks through consistent policy implementation, capacity building, and technology standardization will be crucial for sustaining market momentum.

Future Outlook and Growth Forecast
The future of the India solar rooftop market looks highly optimistic. According to industry estimates, the market is expected to grow, with cumulative rooftop capacity projected to exceed 35 GW by 2030.
Key trends that will shape the next phase of growth include:
- Residential Solar as a Service (RaaS): Emergence of OPEX and leasing models tailored for homeowners and small businesses.
- Integration with Battery Storage: As lithium-ion battery prices continue to fall, hybrid solar + storage solutions will become mainstream.
- Digitalization and Smart Grids: Increasing deployment of AI-driven analytics, smart inverters, and cloud-based energy platforms.
- Green Building Mandates: Regulatory requirements for solar adoption in new residential and commercial construction projects.
- Carbon Credit Monetization: Rooftop solar users will increasingly benefit from carbon offset programs and carbon credit markets.
