₹1 Lakh Solar Subsidy Tamil Nadu 2026: ₹78,000 + ₹22,000

Short answer: in 2026 a Tamil Nadu home can get up to ₹1,00,000 in subsidy for rooftop solar. That is ₹78,000 from the central PM Surya Ghar: Muft Bijli Yojana plus a ₹22,000 Tamil Nadu state top-up (G.O. (Ms) No. 102, Energy Department, 19 September 2026). The full ₹1 lakh applies to systems of 3kW and above installed by an empanelled vendor.

Two clocks are running. The central scheme is approved till 31 March 2027, and the state top-up is reported to be limited to the first 1 lakh eligible homes (about ₹50 crore). We are already seeing many families in Cuddalore walk in to apply before the money runs out.

Rules as of October 2026. Government schemes change; we confirm your exact eligibility on the official portal during the free home visit.

Total Subsidy by System Size (Tamil Nadu, 2026)

Both subsidies stop growing at 3kW. A 5kW system still gets ₹1 lakh in total; you pay the rest. That is why 3kW is the best value per rupee for most homes, and 5kW makes sense when your bill is high (two ACs, a big family, or an EV).

What does a 3kW system cost after ₹1 lakh subsidy?

The typical market price of a 3kW on-grid system in Tamil Nadu is around ₹1,80,000 - ₹2,00,000 before subsidy (it depends on roof, structure height and panel brand). After the full ₹1 lakh comes back to your account, the real cost is roughly ₹80,000 - ₹1,00,000 for a system that makes about 12-15 units a day for 25 years.

Who Is Eligible for the ₹22,000 Tamil Nadu Top-up?

Based on G.O. 102 as reported in October 2026:

• Residential homes only. You need a domestic TNEB / TANGEDCO service connection (Tariff 1A). Commercial, industrial, institutional and agricultural connections are excluded.
• Registered on or after 5 August 2026. Applications made on the PM Surya Ghar portal before this date get the central ₹78,000 but not the state top-up. There is no backdated benefit.
• Grid-connected systems. On-grid systems qualify. Grid-connected hybrid systems (with battery) are reported as eligible; pure off-grid systems are not.
• Empanelled vendor only. The installation must be done by a vendor registered on the PM Surya Ghar portal. If you use an unregistered electrician you can lose both subsidies.
• First come, first served. Reports say the state top-up covers the first 1,00,000 eligible applicants, and the budget may run out even earlier.

The central PM Surya Ghar rules also apply: the bill must be in the applicant's name, you must own the house, and the roof must be strong and shade-free.

Why You Should Not Wait

1. The state top-up has a limit. Once the first 1 lakh homes (or the ₹50 crore budget) are used up, the ₹22,000 is gone.
2. PM Surya Ghar is approved till March 2027. Applications take 4-8 weeks from registration to commissioning, so a home that starts in February is cutting it close.
3. Installer queues fill up before deadlines. Every subsidy deadline brings a rush. Booking your site visit now gets you an earlier installation slot.
4. Every month without solar is another full EB bill. A 3kW system saves roughly ₹2,000 - ₹3,000 a month for a typical Cuddalore home.

Step-by-Step: How to Claim ₹1 Lakh (We Do Most of This for You)

1. Free home visit. We check your roof, shading, EB bill and connection type, and confirm you qualify.
2. Portal registration. We register you on pmsuryaghar.gov.in with your Aadhaar-linked mobile number and EB consumer number, and select Surya's Solar as your vendor.
3. Feasibility approval. TANGEDCO approves the technical feasibility, usually within 1-2 weeks.
4. Installation. We install DCR (Made in India) panels, a BIS-approved inverter, hot-dip galvanized structure and 3 separate earthing pits.
5. Inspection and net meter. TANGEDCO inspects the system and fits the bi-directional net meter. Read our net meter guide for Cuddalore.
6. Central subsidy credited. ₹78,000 (for 3kW+) comes directly to your bank account after commissioning.
7. State top-up credited. TEDA pays the ₹22,000 separately by direct benefit transfer to the same account.

Documents to keep ready

• Aadhaar card, with mobile number linked
• Latest EB bill in the applicant's name
• Bank passbook or cancelled cheque (same name)
• Property tax receipt or sale deed
• Passport-size photo

Most common delay: the name on the EB bill does not match the Aadhaar card. If the meter is still in a parent's name, start the name transfer first. We help with this too.

Puducherry homes: the ₹22,000 top-up is a Tamil Nadu scheme, so it does not apply in Puducherry. You still get the central subsidy of up to ₹78,000. Puducherry has also reported its own additional state subsidy for homes (reports mention about ₹9,000-10,000 per kW, up to about ₹30,000); we confirm the current amount with the Electricity Department at your site visit. See our Puducherry solar cost guide.
