Short answer: for a 3 kW home, Tamil Nadu adds ₹22,000 on top of the central ₹78,000 — about ₹1,00,000 combined. Track status on the TNEB USRP / TNPDCL Solar Homes portal after central CFA credits. Applies to domestic consumers who applied on PM Surya Ghar from 5 August 2026; the state top-up arrives as a second DBT.

Fast triage: Searching “TNEB USRP” or “TNPDCL solar subsidy”? Open tnebltd.gov.in/usrp for status / CFA tools after your national file moves. Amounts: ₹35k / ₹70k / ₹1L for 1 / 2 / 3 kW+. Registered before 5 Aug 2026? Central only.

| System size | Central (PM Surya Ghar) | Tamil Nadu top-up | Combined |
|---|---|---|---|
| 1 kW | ₹30,000 | ₹5,000 | ₹35,000 |
| 2 kW | ₹60,000 | ₹10,000 | ₹70,000 |
| 3 kW and above | ₹78,000 | ₹22,000 | ₹1,00,000 |
Both amounts stop rising at 3 kW. A 5 kW plant gets the same ₹1,00,000 as a 3 kW plant — see 3 kW vs 5 kW and how the central bands add up.
So if ₹78,000 arrives on its own, that is expected — not a rejected state claim. Track both on tnebltd.gov.in/usrp (TNPDCL’s rooftop / USRP portal — status, CFA apply helpers, vendor list) and pmsuryaghar.gov.in.

The state allocated ₹50 crore this financial year with a target of one lakh homes by March 2027. The minister said more funds would be sought if demand crosses the target, but nothing guarantees that in advance. A file that clears inspection without corrections gets its central credit — and therefore its state credit — sooner. The usual file-killers are covered in 12 application mistakes.
₹1 lakh off the price is real money, but payback depends on what solar actually saves you. Tamil Nadu domestic bills are bi-monthly and include free initial units, so a small bill has less to offset than the same units would in many other states. A home using a few hundred units per cycle may find a 2 kW plant pays back better than 3 kW; a heavy AC household usually justifies 3 kW or more.
That is the question our free bill check answers: enter your bill, and we estimate size, combined subsidy and payback before you talk to any vendor.

Tamil Nadu adds a state top-up on top of the central PM Surya Ghar subsidy: ₹5,000 for 1 kW, ₹10,000 for 2 kW and ₹22,000 for 3 kW and above. Combined with central CFA (₹30,000 / ₹60,000 / ₹78,000) that is about ₹35,000, ₹70,000 and ₹1,00,000. Notified by G.O. (Ms) No. 102, Energy Department, 19 September 2026; launched 21 September 2026.
Domestic (residential) consumers in Tamil Nadu who applied on the PM Surya Ghar portal from 5 August 2026 onwards, install a grid-connected plant through an empanelled vendor, and qualify for central CFA. Households that registered before 5 August 2026 get only the central subsidy.
No. The minister said that once the central subsidy is credited, the state portal automatically processes and releases the additional state subsidy — consumers do not submit a separate application. Scheme details, vendor list and status are on the TNPDCL USRP portal (tnebltd.gov.in/usrp).
No. Expect two separate Direct Benefit Transfer credits: the central CFA (up to ₹78,000) first, then the Tamil Nadu top-up (up to ₹22,000) after it. Receiving ₹78,000 alone does not mean the state claim failed.
No. Both the central CFA (₹78,000) and the state top-up (₹22,000) stop rising at 3 kW, so a 5 kW plant gets the same ₹1,00,000 combined as a 3 kW plant. Size to your bill, not to the subsidy.
