PM Surya Ghar: Muft Bijli Yojana

Context

PM Surya Ghar: Muft Bijli Yojana has gained renewed attention as states such as Delhi intensify rooftop-solar promotion through complementary incentives. Launched in February 2024, the scheme aims to solarise one crore households and reduce residential electricity expenditure through subsidised rooftop solar.

Scheme Design and Household Support

1. Central Sector Scheme: Implemented by the Ministry of New and Renewable Energy (MNRE) with an outlay of ₹75,021 crore, it supports grid-connected rooftop solar for residential consumers.
2. Capital subsidy: Households receive ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, with standard Central Financial Assistance capped at ₹78,000 for systems of 3 kW or above.
3. Higher support in special-category regions: Eligible special-category States and UTs receive enhanced assistance, helping offset higher installation costs in difficult regions.
4. Concessional finance: Collateral-free, low-interest loans reduce the upfront financing burden, enabling more households to adopt rooftop solar.

How Households Benefit Financially

1. Lower electricity bills: Rooftop generation offsets household consumption, allowing suitably sized systems to significantly reduce or, in some cases, eliminate monthly electricity bills.
2. 300-unit potential: A 3 kW rooftop system can generate more than 300 units per month on average, but this is a generation-based benefit rather than an automatic entitlement to 300 free grid units.
3. Surplus-power export: Excess electricity can be supplied to the grid under applicable net-metering or settlement rules, allowing households to earn from unused generation.
4. Direct subsidy transfer: After installation and verification, eligible assistance is transferred directly to beneficiaries, reducing transaction costs and improving transparency.

Implementation Progress

1. Rapid scale-up: By August 2026, more than 51 lakh households had benefited and around 14.8 GW of rooftop-solar capacity had been commissioned, showing significant expansion of residential solar.
2. Credit uptake: Concessional loans have been sanctioned to a large number of applicants, indicating that affordable finance is helping address the upfront-cost barrier.
3. State convergence: States can provide additional incentives or implementation support, allowing the central scheme to adapt to local electricity-market and consumer conditions.

Significance

1. Distributed energy transition: Rooftop solar generates electricity close to the point of use, reducing exclusive dependence on centralised power generation.
2. Household energy security: Lower recurring electricity bills can improve disposable income and partly protect consumers from future tariff increases.
3. Grid support: Daytime rooftop generation can reduce demand on distribution networks and support renewable integration, provided net-metering and grid-management systems remain effective.
4. Green industrial ecosystem: Large-scale rooftop deployment expands demand for solar modules, inverters, installers and maintenance services, supporting domestic clean-energy supply chains and jobs.

FAQs
