India Solar Rooftop Market Overview

India's rooftop solar market is gaining momentum as the country strengthens its renewable energy ecosystem. Falling module prices, supportive regulatory frameworks, and attractive financial incentives have made rooftop solar systems more accessible to households, commercial establishments, and industrial units.

In the first half of 2025 alone, India added nearly 3.2 GW of rooftop solar capacity, registering an 86% year-on-year increase. The residential segment accounted for nearly 74% of new installations, underlining the growing participation of homeowners in clean energy adoption. Gujarat, Maharashtra, and Uttar Pradesh emerged as major contributors, with Gujarat accounting for approximately 29% of total installed rooftop capacity.

The government's flagship rooftop solar programs have enabled over 13 million households to register under subsidy schemes. By mid-2024, more than 385,000 residential installations were completed, adding nearly 1.8 GW of capacity. These initiatives are accelerating decentralized energy generation and reducing dependency on conventional power sources.

India Solar Rooftop Market Dynamics

The India Solar Rooftop Market is being shaped by a combination of policy support, economic incentives, and technological advancements. One of the primary growth drivers is the government's commitment to renewable energy, reflected in the allocation of nearly USD 9 billion to support rooftop solar installations across 10 million households.

In 2025, rooftop solar installations witnessed a 158% year-on-year increase, highlighting the effectiveness of these initiatives. Regionally, the top ten states contribute over 80% of national installations, emphasizing the role of state-level policies in market expansion.

Another major factor is the declining cost of solar panels, inverters, and balance-of-system components. As manufacturing capacity increases and supply chains strengthen, system costs continue to fall, making rooftop solar financially viable for a broader consumer base.

Rising electricity tariffs have further encouraged residential and commercial users to invest in rooftop solar systems for long-term savings. Additionally, net metering policies allow consumers to sell excess power back to the grid, improving project returns and boosting adoption.

The market also presents significant untapped potential, especially among micro, small, and medium enterprises (MSMEs), which are estimated to have over 15 GW of rooftop solar potential. Increased awareness, easier financing options, and continued policy backing are expected to further accelerate growth.

Key Drivers of Growth

Several key factors are driving the expansion of the India Solar Rooftop Market:

Strong Government Support: Subsidies, tax benefits, and simplified approval processes are encouraging adoption.

Declining Technology Costs: Reduced prices of solar modules and components are lowering upfront investment requirements.

Rising Power Tariffs: Increasing electricity costs are making solar energy an attractive alternative.

Environmental Awareness: Growing concern about climate change is motivating consumers to adopt renewable energy.

Energy Security: Rooftop solar reduces dependence on centralized power generation and improves reliability.

Together, these drivers are creating a favorable environment for sustained market growth.

Market Opportunities

The evolving energy landscape in India presents significant opportunities across multiple segments. The growing demand for energy storage systems, particularly lithium-ion batteries, is opening new avenues for integrating rooftop solar with backup power solutions.

Solar-powered irrigation systems are gaining popularity in rural areas, offering farmers a reliable and cost-effective alternative to diesel pumps. The expansion of smart grids and advanced metering infrastructure is also creating opportunities for technology providers.

Furthermore, India's focus on green buildings and sustainable urban development is driving demand for integrated solar solutions. The emerging green hydrogen ecosystem and offshore wind projects further complement the renewable energy value chain, creating long-term investment prospects.

India Solar Rooftop Market Segment Analysis

Based on capacity, the 11-100 kW segment dominates the India Solar Rooftop Market. This category primarily serves small commercial establishments, housing societies, and mid-sized industries. It offers an optimal balance between affordability and scalability, making it the preferred choice for many users.

This segment benefits from government subsidies, net metering policies, and relatively short payback periods. Rising electricity prices and falling system costs have further enhanced its attractiveness. The ability to meet a significant portion of energy demand while generating surplus power for grid export ensures strong returns on investment.

As a result, the 11-100 kW segment is expected to remain the leading contributor to market growth over the forecast period.

Regional Analysis

In 2024, South India emerged as the dominant region in the India Solar Rooftop Market. States such as Tamil Nadu, Karnataka, Andhra Pradesh, Telangana, and Kerala benefit from high solar irradiation, supportive policies, and strong urban infrastructure.

Progressive net metering regulations and state-level incentives have encouraged rapid adoption. Major cities like Bengaluru, Chennai, and Hyderabad serve as hubs for commercial and industrial installations, while increasing environmental awareness is driving residential demand.

Other regions, including Western and Northern India, are also witnessing rapid growth, supported by expanding urbanization and favorable regulatory environments.

Recent Developments

Tata Power Renewable Energy Ltd. commissioned a 300 MW solar project in Rajasthan in November 2025, strengthening India's clean energy infrastructure.

Waaree Energies Ltd. began trial production at its 5.4 GW solar cell gigafactory in Gujarat in January 2025, enhancing domestic manufacturing capabilities.

Amplus Solar rebranded as Gentari in May 2025, integrating its rooftop and distributed solar operations into a broader clean energy platform.

These developments highlight the increasing scale and sophistication of India's solar ecosystem.

Future Outlook

The India Solar Rooftop Market is expected to witness sustained growth over the next decade, supported by ambitious renewable energy targets, technological innovation, and expanding consumer participation.
