Examine the financial architecture (CFA + subsidised loans) of India's rooftop solar push and its adequacy in achieving India's renewable energy targets.

India's rooftop solar push rests on PM Surya Ghar: Muft Bijli Yojana, approved by the Cabinet in February 2024 with an outlay of ₹75,021 crore to cover one crore households [1]. Its financing blends an upfront capital subsidy with cheap credit — a design that lowers entry cost effectively, but whose adequacy for India's 500 GW non-fossil goal is only partial.

The financial architecture

• Central Financial Assistance (CFA): 60% of system cost up to 2 kW and 40% of the additional cost for the 2–3 kW slab — ₹30,000 (1 kW), ₹60,000 (2 kW) and ₹78,000 (3 kW and above) [1].
• Subsidised credit: collateral-free loans up to ₹2 lakh at around 7% interest through public sector banks, bridging the residual cost [2].
• State layer: states add subsidy top-ups and run DISCOM net-metering and vendor empanelment, making delivery a Centre–State joint exercise.
• Delivery mode: a National Portal with vendor ratings and benefit calculators enables DBT-style, leakage-resistant disbursal [3].

Assessing adequacy

• Strengths: the CFA covers most of a small system's cost; an assured saving of about ₹15,000 a year for a 300-unit household improves payback [2]. Scale has followed — roughly 39.7 lakh systems covering ~48 lakh households by mid-2026 [3].
• Gaps: the subsidy is capped at 3 kW, leaving group housing and MSME rooftops outside; the ₹2 lakh loan ceiling and residual 40% burden still deter low-income families; bank outreach remains uneven.
• Structural constraint: financially stressed DISCOMs resist net metering, since rooftop solar erodes their paying consumer base — delaying sanction and subsidy release.

The architecture is sound in intent but insufficient alone: capital support cannot substitute for distribution-sector reform. Aligning DISCOM compensation with rooftop growth, widening loans to aggregators and RESCO models, and simplifying state-level clearances would convert this subsidy design into a durable pillar of India's clean-energy commitments.
