Uttar Pradesh Becomes India's Rooftop Solar Leader as Lucknow Tops National Installations

Uttar Pradesh has emerged as India's fastest-growing rooftop solar market, with Lucknow overtaking Surat to become the country's leading city for residential rooftop solar installations.

Driven by generous government subsidies, simplified implementation and extensive public outreach, the state now contributes more than 20% of India's monthly rooftop solar installations, reinforcing its position as a key player in the country's renewable energy transition.

Lucknow Becomes India's Top Rooftop Solar City

According to the Uttar Pradesh government, Lucknow has crossed the milestone of 1.02 lakh rooftop solar installations by mid-2026, surpassing Surat to become India's leading city for rooftop solar adoption.

The achievement reflects the state's focused efforts to promote clean energy through financial incentives, administrative support and public awareness campaigns.

PM Surya Ghar Scheme Powers Solar Growth

Officials credit much of the growth to the PM Surya Ghar Muft Bijli Yojana, supported by an additional state subsidy of up to Rs 30,000.

The combined incentives significantly reduce the upfront installation cost of rooftop solar systems, allowing households to recover their investment within three to four years through lower electricity bills.

The subsidy-driven model has made rooftop solar more affordable for middle-class households across the state.

Government's Multi-Level Strategy Drives Adoption

Rather than relying only on awareness campaigns, Uttar Pradesh adopted a coordinated implementation strategy.

Key initiatives included:

• Encouraging households receiving smart meters to install rooftop solar systems.
• Partnering with over 700 Resident Welfare Associations (RWAs) for awareness drives.
• Involving school students to promote renewable energy awareness within families.
• Monitoring implementation at the district level while coordinating progress centrally.

The approach has helped accelerate residential solar adoption across urban areas.

Property Tax Rebate Encourages Homeowners

The Lucknow Municipal Corporation further boosted adoption by offering a 10% rebate on property tax for homeowners installing rooftop solar systems.

The additional financial incentive has encouraged more households to switch to solar power while reducing long-term electricity costs.

Strong Vendor Network Supports Expansion

Another major factor behind Uttar Pradesh's rapid progress has been the expansion of its solar installation ecosystem.

The number of empanelled vendors reportedly increased from around 600 to nearly 6,000, following government-supported training programmes and seminars.

A larger vendor base has improved accessibility, reduced installation delays and strengthened consumer confidence.

Rooftop Solar Becoming More Affordable

The economics of rooftop solar have improved considerably.

Under the current subsidy structure:

• A large portion of the installation cost for a 3-kilowatt solar system is covered through government assistance.
• Concessional bank loans are available at interest rates of around 6%.
• Average payback period has reduced to three to four years.
• Solar systems are expected to operate for nearly 25 years, offering long-term savings.

Challenges Still Remain

Despite the rapid growth, some hurdles continue.

Commercial rooftop solar adoption remains lower than residential installations due to different compensation mechanisms for surplus electricity exported to the grid.

Regional disparities also persist.

While Lucknow has crossed one lakh installations, several districts in eastern Uttar Pradesh continue to witness slower adoption because of weaker vendor networks and lower urbanisation.

Uttar Pradesh Sets a Renewable Energy Example

Industry experts believe Uttar Pradesh's success demonstrates how a combination of subsidies, local administration, public participation and financial incentives can accelerate rooftop solar adoption.

As India pushes towards cleaner energy sources, the state's model could serve as a blueprint for expanding renewable energy adoption across the country.
