Tamil Nadu state top-up raises the 3 kW subsidy to ₹1 lakh
Tamil Nadu has added a state rooftop solar subsidy on top of the central PM Surya Ghar: Muft Bijli Yojana assistance. For eligible residential consumers, the combined central and state solar subsidy Tamil Nadu now provides is ₹35,000 for a 1 kW system, ₹70,000 for 2 kW and ₹1,00,000 for systems of 3 kW and above. The maximum combines the existing ₹78,000 central benefit with the new ₹22,000 state solar subsidy Tamil Nadu announced in September 2026.
This is an additional benefit, not a replacement for PM Surya Ghar. A homeowner who qualifies for both schemes receives the central amount and the state top-up under their respective application process. The money is credited to the beneficiary's bank account after installation and the required checks, with the announced payment window running from 7 to 30 days after installation. GenSolar shows each part separately in the proposal so customers can see the system quote, central support and state support without mixing them together.
| System size | PM Surya Ghar central | Tamil Nadu state | Combined subsidy |
|---|---|---|---|
| 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 |

What the new 3 kW cost and loan example looks like
Use a ₹2,20,000 residential system as a simple worked example. The customer begins with an adjustable down payment of ₹19,999. A bank sanctions ₹2,00,000 for the installation. After the eligible 3 kW system is installed and approved, the government subsidy received is ₹1,00,000 — ₹78,000 from PM Surya Ghar and ₹22,000 from Tamil Nadu. That subsidy is then adjusted against the loan, bringing the final loan amount to ₹1,00,000. On the stated project example, the effective cost figure after the down payment and subsidy is shown as ₹80,001.
At 6% annual interest on a reducing balance for 48 months, the EMI on ₹2,00,000 is approximately ₹4,697 per month during the first 7 to 30 days. Once the ₹1,00,000 subsidy is received and adjusted, the EMI on the remaining ₹1,00,000 is approximately ₹2,349 per month. These are planning figures: the final system quote depends on panel selection, mounting type and site conditions, while the bank's approved interest rate and tenure determine the actual EMI. Use the solar calculator for a bill-based estimate and request a site survey before choosing finance.
- Total system cost: ₹2,20,000
- Down payment: ₹19,999 (adjustable)
- Bank loan sanctioned: ₹2,00,000
- Government subsidy received: ₹1,00,000
- Final loan amount after subsidy adjustment: ₹1,00,000
- Effective cost in the stated example: ₹80,001
How to apply for the Tamil Nadu solar subsidy from 21 September 2026
The dedicated Tamil Nadu online portal begins accepting applications on 21 September 2026. Keep the consumer name, TANGEDCO service number, a recent electricity bill, Aadhaar, bank details and roof-ownership records ready. The applicant's name should match the domestic electricity connection. A mismatch is one of the most common reasons a subsidy file is delayed or returned.
The central and state applications must support the same eligible installation. Register for PM Surya Ghar, complete the required feasibility and vendor stages, and file the Tamil Nadu top-up through the new state portal. The system should use eligible modules and certified equipment, and the installation, photographs, invoices, commissioning details and bank information must remain consistent across the records. Do not treat a verbal promise as approval; retain portal acknowledgements for both applications.
- Confirm that the TANGEDCO connection is residential and in the applicant's name
- Register and complete the PM Surya Ghar central application
- Apply through the dedicated Tamil Nadu portal from 21 September 2026
- Install through an eligible vendor using compliant modules and equipment
- Complete inspection, net metering and commissioning records
- Track the bank credit during the announced 7–30 day post-installation window
Who can claim the combined subsidy
The support is intended for residential rooftop solar. The home needs a valid domestic electricity connection, a roof owned by the applicant or under the applicant's exclusive use, and a bank account for direct credit. The installation must meet the central and state technical requirements. Commercial and industrial connections do not receive this residential subsidy; those projects are evaluated through savings, accelerated depreciation, GST treatment, CAPEX or OPEX models instead.
The maximum ₹1 lakh amount begins at 3 kW. Installing 5 kW or 10 kW does not increase the combined amount beyond ₹1,00,000 under the announced slabs. System size should therefore follow the household's electricity consumption, future loads such as an electric vehicle or additional air conditioning, and usable shadow-free roof area — not the desire to chase a larger subsidy.
How GenSolar handles both applications
GenSolar Energy is an authorised Tata Solar dealer and a registered rooftop solar vendor. Our team checks the electricity bill and applicant details, surveys the roof, sizes the system, prepares the technical proposal and files the PM Surya Ghar central application. From the Tamil Nadu portal launch, we also prepare and submit the state top-up application using the same verified consumer, installation and bank records.
After installation, we coordinate the TANGEDCO net-metering file, upload the required photographs and equipment details, support inspection and commissioning, and track the subsidy stages. The subsidy belongs to the beneficiary and is credited to the beneficiary's bank account; GenSolar does not receive it on the customer's behalf.
