The India rooftop solar market is valued at USD 5.36 billion in a recent year, growing from a value of USD 5.36 billion previously, based on a detailed historical revenue series and industry forecasts. Installed capacity reached approximately 10.8 GW by March and expanded to about 11.87 GW grid‑connected rooftop by end‑of‑year. Growth is fuelled by streamlined net‑metering, major government subsidy schemes under PM Surya Ghar, and sharply declining module and inverter costs.
The rooftop solar landscape is led by South Indian states (Andhra Pradesh, Telangana, Karnataka, Tamil Nadu), due to strong state net‑metering policies, high urban industrial base, and active DISCOM support. Additionally, Gujarat and Maharashtra rank among the top in installations, owing to robust MSME uptake and scalable industrial and residential adoption in states like Gujarat, Haryana, and Delhi. Chandigarh also features prominently in government rooftop deployment, motivated by aggressive municipal solar saturation campaigns.
Market Segmentation
By Application Type
India rooftop solar market is segmented into Residential, Commercial & Industrial (C&I), and Institutional & Government systems. In 2024 C&I dominates with approximately 60% market share. This is because large-angle policies and subsidy channels lead industrial and commercial entities to adopt rooftop solar at scale, leveraging CAPEX investments and net‑metering returns. Residential uptake lags at around 27% share due to slower consumer awareness and financing access. Government/institutional segment remains a smaller share though visible in certain states like Chandigarh. C&I systems dominate due to high rooftop availability, predictable loads, and attractive returns in industrial clusters and commercial complexes. Residential adoption, while growing, remains limited by consumer awareness, financing constraints, and rooftop suitability.
By Ownership Model
India rooftop solar is segmented into CAPEX model, OPEX/RESCO model, and Leasing structures. CAPEX installations account for about 69% share of new installations (Q1 2024), capturing majority of cumulative capacity. RESCO/OPEX model and leasing share smaller portions. CAPEX leads because direct ownership offers higher long‑term savings, government subsidy alignment, and simplified net‑metering credits. Commercial and industrial users prefer owning systems to optimize ROI over 5–7 years. RESCO models continue in residential or smaller institutional cases where capex remains a barrier. CAPEX dominates due to alignment with subsidy mechanisms, predictable returns for larger consumers, and strong bank financing for business users. OPEX and leasing fill gaps where upfront capex is less feasible.
Competitive Landscape
India rooftop solar market is dominated by a handful of major players including Tata Power Solar, Amplus Solar, CleanMax Enviro, Fourth Partner Energy, and ReNew Power. These firms lead due to integrated EPC plus RESCO services, deep state relationships, and multi-sector footprints.

India Rooftop Solar Market Analysis
Growth Drivers
Net Metering Policies and DISCOM Incentives
Urban electricity access in India stands at 99.5 percent of the population in 2023, up from rural access at 99.2 percent, as per World Bank data. These high electrification levels in urban centers have enabled DISCOMs to operate net‐metering schemes at scale. In states such as Tamil Nadu and Karnataka, DISCOMs have credited rooftop solar consumers through net‐metering within billing cycles covering over 1,300 hours of excess energy fallback in FY 2023 – 2024 (CEA dashboard reports), creating viable paybacks and utility support. These policy frameworks and DISCOM incentives have underpinned widespread rooftop solar uptake in C&I sectors in major cities.
Urban Residential Electrification Goals
India achieved near-universal urban electrification with 99.5 percent access by 2023, driven by programs like Saubhagya (Pradhan Mantri Sahaj Bijli Har Ghar Yojana) and DDUGJY. Despite widespread connectivity, household sanctioned load capacity remains low, typically between 1 to 2 kW per customer (CEA reporting FY 2022–24), prompting many urban households in Delhi, Mumbai, and Bengaluru to seek rooftop solar to meet rising appliance demand. This load-based stress is pushing homeowners toward rooftop adoption to supplement grid capacity, motivated by reliability concerns and elevated power consumption patterns in urban households emitting peak loads around 1,400 MW daily.
Market Challenges
Delays in Net‑Metering Approvals
In Puducherry, a rooftop solar consumer received a ₹98,139 electricity bill instead of a ₹6,722 credit, after installation in August 2024 due to billing misprocessing and net‑metering delays, and required more than one month of interaction with government offices to correct it. Similar processing issues have surfaced in Tamil Nadu under PM Surya Ghar Yojana, where incorrect application data entries delayed subsidy disbursal worth ₹236 crore as of mid‑2025, causing multiple reapplications and stalled consumer installations. These cases highlight systemic friction in approvals and subsidy linkage for rooftop solar.
Financial Risks in RESCO Model
As of early 2024, nearly 1.8 million rooftop solar subsidy applications were received under the PMSGY scheme, resulting in around 385,000 installations totaling 1.8 GW capacity. While accelerated, such volumes also exposed resilience risks: RESCO developers must carry upfront capital against uncertain subsidy flow timelines. State programme implementation and subsidy disbursement delays have strained liquidity for third-party operators, with limited bank refinancing options under industry-sourced credit facilities, affecting project onboarding across residential clusters.
Opportunities
Integration with Battery Storage
India’s initiatives in utility-scale battery energy storage systems (BESS) include pilot projects like the BRPL-GEAPP public-private partnership in Delhi, servicing 12,000 low-income customers approved mid‑2024. As of late 2023, India had commissioned BESS capacity of over 600 MWh at industrial and grid level (CEA and GEAPP summary). Rooftop solar plus home battery setups of typical 5–10 kWh are increasingly adopted in urban households in metro cities like Delhi and Bengaluru. Rising electricity peak demands (daily peak load ~56,631 MW FY 2024) and DISCOM grid stress provide a compelling rationale for hybrid rooftop–storage systems in both commercial and residential settings.
Peer‑to‑Peer Solar Trading via Blockchain
India has piloted solar peer-to-peer (P2P) energy trading using blockchain in states like Maharashtra and Karnataka via DISCOM-led platforms in 2023. P2P exchanges connected over 500 small-scale prosumers with collective rooftop capacity exceeding 20 MW in pilot districts. Market regulators, including MERC and KERC, approved trial trading programs in 2023, allowing rooftop solar generators to transfer surplus energy within local grids. With urban electrification reaching saturation (99.5 percent access), these P2P initiatives enable monetization of excess rooftop generation, especially in Delhi and Hyderabad municipal areas, unlocking new revenue channels for residential and C&I rooftop owners.
Future Outlook
Over the next six years, India rooftop solar market is expected to grow significantly, driven by expanded government subsidy schemes (PM Surya Ghar), increased DISCOM collaboration on net‑metering, falling module prices, and rising corporate sustainability goals. Industrial and residential demand are expected to grow driven by MSME electrification, energy cost savings, and increasing residential electrification. Battery‑solar hybrid and IoT‑based rooftop management innovations will add momentum.
