Rooftop Solar Subsidy in Tamil Nadu
Residential rooftop solar in Tamil Nadu qualifies for the central PM-Surya Ghar: Muft Bijli Yojana subsidy of up to ₹78,000. This guide covers the exact subsidy amounts, DISCOM net-metering process, disbursement timeline, and 8 verified installers you can request a quote from directly.
Central subsidy — PM-Surya Ghar: Muft Bijli Yojana
Amount is fixed nationally by the Ministry of New & Renewable Energy (MNRE). Direct benefit transfer (DBT) to your Aadhaar-linked bank account after commissioning.
| System size | Central subsidy | Typical net cost (₹1.6-2.2 L before subsidy) |
|---|---|---|
| 1 kW | ₹30,000 | ₹35,000 – ₹90,000 |
| 2 kW | ₹60,000 | ₹80,000 – ₹1.2 L |
| 3+ kW | ₹78,000 | ₹1.0 – ₹1.4 L |
The subsidy is the same in every state — this table applies verbatim to Tamil Nadu. Your out-of-pocket cost is the vendor quote minus this amount, credited within a few weeks of commissioning.

Frequently asked questions
How much subsidy do I get for a 3 kW rooftop solar system in Tamil Nadu?
The central PM-Surya Ghar: Muft Bijli Yojana pays a flat ₹78,000 subsidy for a 3 kW residential rooftop solar system anywhere in India, Tamil Nadu included. This is credited to your bank account (DBT) after commissioning and successful net-meter installation. TANGEDCO (Tamil Nadu Generation and Distribution Corporation) handles the Tamil Nadu side of net-metering approval.
Does Tamil Nadu offer an extra state top-up on top of PM-Surya Ghar?
Tamil Nadu residents primarily receive the central PM-Surya Ghar subsidy (up to ₹78,000 for a 3 kW system). Some states run additional programmes with variable top-ups — the position changes yearly. Confirm the current top-up with TANGEDCO (Tamil Nadu Generation and Distribution Corporation) or on the state's energy department website before signing an installer's quote.
How long after installation does the subsidy hit my bank?
In Tamil Nadu, dealers typically report subsidy DBT credit within 45 days from commissioning + net-meter approval. This varies with paperwork completeness — subsidy claim, DISCOM sanction letter, plant commissioning certificate, and Aadhaar-seeded bank account must all be in order.
Can I combine the PM-Surya Ghar subsidy with a solar loan?
Yes. Most public sector banks (SBI, Canara, BoB) and NBFCs offer collateral-free solar loans that cover 70-90% of the pre-subsidy system cost at 8-11% p.a., 5-7 year tenure. The subsidy DBT is credited to the same bank account and can be used to prepay the loan without penalty at most banks. Ask your Tamil Nadu installer for their bank tie-up — most offer parallel EMI processing.
Which installer should I pick in Tamil Nadu?
Any MNRE-empanelled vendor (visible on the pmsuryaghar.gov.in vendor list) is eligible to claim the subsidy on your behalf. Compare 2-3 quotes on: panel make (Tier-1 mono-PERC), inverter brand + warranty (min 10 years), mounting structure, and the subsidy paperwork commitment.
