India Rooftop Solar Photovoltaic Installation Market Scope

Growth Drivers

Priority Sector Lending (PSL) Norms Improving Financing Accessibility for Residential Rooftop Solar Installations

Access to affordable financing remains one of the primary constraints limiting residential rooftop solar adoption, as the upfront investment required for system installation often discourages households despite long-term electricity savings. The Reserve Bank of India's (RBI) revised Priority Sector Lending (PSL) guidelines, effective April 1, 2025, address this financing gap by retaining the USD 11,500 limit for individual household renewable energy installations while increasing the lending ceiling for renewable energy-based power generators and public utilities from USD 3.45 million to USD 4.02 million.

By classifying rooftop solar financing under the PSL framework, banks are required to allocate a portion of their lending portfolio to renewable energy projects, encouraging greater participation from public and private sector commercial banks, Urban Cooperative Banks, and other lending institutions in financing rooftop solar systems.

The policy also expands access to formal credit in semi-urban and smaller towns through Urban Cooperative Banks, enabling lower- and middle-income households to finance rooftop installations using affordable EMI-based repayment options rather than relying solely on upfront capital. Lower financing costs further enable EPC companies and NBFCs to introduce vendor-backed financing solutions, improving customer affordability and project conversion rates.

The importance of strengthening credit availability is further reflected in SBI Research's recommendation to substantially expand PSL coverage for renewable energy and rooftop solar, highlighting financing as a critical enabler of India's clean energy transition and long-term rooftop solar deployment

Recent Trends

Growing Transition from PERC to N-Type TOPCon Bifacial Modules in Rooftop Solar Installations

Indian rooftop solar buyers are increasingly choosing n-type TOPCon bifacial modules because rooftop area has become a greater constraint than upfront system cost. WRI India notes that rapid urbanization has led to a higher share of apartment and rental housing, where individual households have limited usable roof space. Under these conditions, buyers cannot significantly expand system size, making higher-output modules the most practical way to maximize electricity generation and reduce grid consumption within the available rooftop footprint.

This preference is strengthening demand for TOPCon technology, which delivers commercial efficiencies of 22–23%, enabling higher energy generation per square meter than conventional mono-PERC modules. For buyers financing rooftop systems through loans or subsidy-linked programs, long-term energy yield is equally important. TOPCon modules typically exhibit annual degradation rates of 0.40–0.45%, compared with approximately 0.55% for standard PERC modules, preserving generation over the system's operating life and improving lifetime returns.

Manufacturers are aligning their product portfolios with these consumer priorities. In June 2026, Bluebird Solar introduced its G12R n-type TOPCon bifacial series, offering outputs of up to 630 Wp at 23.32% efficiency, supported by a 12-year product warranty and a 30-year power output warranty. Such offerings address buyers seeking higher generation from limited rooftop space while ensuring long-term performance over typical financing periods.

India Rooftop Solar Photovoltaic Installation Market Opportunities and Challenges

Distribution Transformer Saturation Restricting Rooftop Solar Connections While RDSS Upgrades Create New Installation Opportunities

The limited capacity of local distribution transformers (DTRs) has become a key constraint for rooftop solar installations in several high-adoption urban and semi-urban areas across India. State regulations restrict the total rooftop solar capacity that can be connected to a single transformer to maintain grid stability. For instance, Andhra Pradesh's Solar Rooftop Policy allows rooftop solar installations up to 80% of a transformer's rated capacity, while the Delhi Electricity Regulatory Commission has proposed a 15% limit on cumulative rooftop solar capacity connected to an individual transformer. Once these limits are reached, DISCOMs stop approving additional net-metering applications, even if consumers have sufficient rooftop space and are willing to install solar systems. As a result, EPC companies and installers are unable to execute new projects in transformer-saturated areas despite continued market demand.

This challenge is creating an opportunity through the Revamped Distribution Sector Scheme (RDSS). The Government of India has approved USD 327 billion worth of projects under RDSS, including USD 177 billion for strengthening distribution infrastructure through substation expansion, transformer capacity upgrades, and feeder segregation. As distribution transformers are upgraded, their rooftop solar hosting capacity increases, allowing DISCOMs to approve additional rooftop connections. These infrastructure improvements are opening previously saturated areas for new installations, creating fresh business opportunities for rooftop solar installers and EPC companies while supporting the continued expansion of the India rooftop solar PV installation industry.

Segmentation Insights

First-Time Rooftop Deployments Drive New Installation to Approximately 92% Share

Supported by the continued rollout of the government schemes, which is primarily designed to encourage first-time rooftop solar adoption. According to the Ministry of New and Renewable Energy (MNRE), July 2026 recorded the scheme's highest-ever monthly achievement, with 5.06 lakh households installing rooftop solar systems. In addition, the government had disbursed USD 3.2 billion in subsidies through the Direct Benefit Transfer (DBT) mechanism as of July 2026. Since these incentives are available for new rooftop solar installations rather than system replacements or upgrades, the program continues to drive greenfield residential and commercial deployments, reinforcing the dominance of the new installation segment.

This trend is reflected in industry performance. For instance, Tata Power Solaroof surpassed 1 GWp of cumulative rooftop solar installations during the first nine months of FY2025–26, adding more than 170,000 new residential and commercial & industrial installations, compared with 38,494 installations during the corresponding period of FY2024–25. With the Government of India targeting 30 GW of cumulative rooftop solar capacity by FY2026–27, first-time installations are expected to remain the largest contributor to market growth as untapped rooftop potential across urban and semi-urban regions continues to be developed. By installation type the market is further segmented into the following categories:

• New Installation
• Retrofit/Replacement
• Expansion

High-Capacity Rooftop Solar Systems Above 100 kW Power Market Expansion

Systems above 100 kW account for approximately 55% of India's rooftop solar photovoltaic (PV) market by installed capacity, reflecting the significant contribution of large commercial and industrial (C&I) installations to overall rooftop deployment. The relatively strong position of larger systems is supported by regulatory provisions that provide eligible C&I consumers with additional options for procuring and consuming renewable electricity. Under the Electricity (Promoting Renewable Energy Through Green Energy Open Access) Rules, 2022, as amended by the Second Amendment Rules, 2023, consumers with a sanctioned load or contract demand of 100 kW or above, either through a single connection or multiple connections aggregated within the same electricity division of a distribution licensee, are eligible for Green Energy Open Access. This enables qualifying C&I consumers to procure renewable electricity directly from generators through open-access arrangements, including long-term power purchase agreements, rather than relying exclusively on conventional grid supply and rooftop net-metering mechanisms.

Regulatory developments at the state level are further supporting the deployment of higher-capacity rooftop systems. In February 2024, the Rajasthan Electricity Regulatory Commission increased the state's rooftop solar net-metering capacity limit from 500 kW to 1 MW through a suo motu order. The revision enables large institutions and industrial establishments with sufficient rooftop space to install higher-capacity systems while continuing to utilize the net-metering framework.

Corporate investment is also demonstrating the growing role of large-scale rooftop installations within India's capacity mix. In January 2026, Roofsol Energy commenced development of 12.8 MWp of rooftop solar capacity across Motherson Group's manufacturing facilities, with the installations expected to generate more than 14 million units of electricity annually. At the state level, Maharashtra's cumulative rooftop solar capacity exceeded 5,000 MW in February 2026, highlighting the increasing scale of distributed solar deployment. At the same time, the introduction of Grid Support Charges under Maharashtra Electricity Regulatory Commission (MERC) Order 75 of 2025 for certain installations above 10 kW is increasing the importance of optimizing larger C&I systems for on-site consumption and reducing reliance on grid exports.

Accordingly, India's rooftop solar market is increasingly characterized by a substantial higher-capacity C&I segment, supported by regulatory access to renewable power procurement, expanded state-level net-metering limits, and continued corporate investment. By capacity, the market can therefore be further segmented into the following sub-categories:

• Up to 3 kW
• 3–10 kW
• 10–100 kW
• Above 100 kW
