PM Surya Ghar Muft Bijli Yojana (Updated for 2025)

As of August 2025, the scheme continues to provide substantial subsidies for rooftop solar. For systems up to 2 kW, the subsidy is ₹30,000 per kW. For the third kW, an additional subsidy of ₹18,000 is provided, capping the total at ₹78,000 for systems of 3 kW and above. The application remains streamlined through the national portal.

National Solar Mission Phase III

The mission now targets 500 GW of renewable energy by 2030, with a heavy emphasis on domestic manufacturing through the PLI (Production Linked Incentive) scheme to reduce import dependency.

State-wise Policies (Example: Maharashtra)

Maharashtra's latest policy offers an additional state-level capital subsidy for specific agricultural feeders, and has simplified the net metering approval process to a 15-day timeline for residential applicants.

MNRE Guidelines for Hybrid Systems

Recent guidelines focus on standardizing Solar+Storage systems, providing benchmarks for battery performance, and ensuring seamless integration with the grid to improve stability.

Market Trends (as of Mid-2025)

The market is seeing a surge in utility-scale solar parks in states like Rajasthan and Gujarat. The C&I (Commercial & Industrial) rooftop sector is the fastest-growing segment due to favorable open-access policies and rising grid tariffs.

Major Players

Profiles of leading EPC companies (e.g., Tata Power Solar, Adani Green Energy), key domestic module manufacturers (e.g., Waaree, Vikram Solar), and top inverter suppliers active in the Indian market.

Case Studies

In-depth analysis of landmark projects like the Bhadla Solar Park (Rajasthan) and the world's largest floating solar plant, highlighting execution strategies and performance data.

Regional Variations

Performance analysis based on India's diverse climate zones. For example, bifacial modules show over 12% higher yield in the high-albedo conditions of the Rann of Kutch compared to standard modules in coastal regions.
