Tamil Nadu Solar Subsidy 2026: How the Central + State Subsidy Can Help Homeowners
Every month, when the EB bill arrives, many Tamil Nadu families look at the amount and think, “Intha bill konjam adhigama poiduchu…” For a family in Erode, Coimbatore, Salem or Chennai, a monthly electricity bill of ₹4,000–₹6,000 can make rooftop solar feel worth considering.
But the next questions are usually practical:
Veetukku solar panel install pannalama?
Solar potta evlo selavu aagum?
Government subsidy evlo?
Central government subsidy vera, Tamil Nadu government subsidy vera?
₹1 lakh subsidy-nu solranga—adhu eppadi work aagum?
In 2026, eligible residential electricity consumers in Tamil Nadu may receive assistance under both the Central Government’s PM Surya Ghar: Muft Bijli Yojana and Tamil Nadu’s additional rooftop-solar subsidy. For a qualifying 3 kW system, the combined assistance can reach up to ₹1,00,000 under the applicable scheme structure. However, this is not an automatic payment for every homeowner. Eligibility, installation, commissioning, net metering, documentation and scheme rules all matter.
Why Are More Tamil Nadu Homes Looking at Solar?
Electricity consumption has become an important monthly household expense. Air conditioners, refrigerators, water pumps, washing machines, induction stoves and other appliances can push a home into higher consumption slabs.
Rooftop solar is attractive because it can help a household generate electricity on its own roof. It may also make a portion of future electricity costs more predictable.
The decision is usually based on three questions:
How much electricity does the home consume?
Is the roof suitable for solar panels?
How much will the system cost after eligible subsidy?
Government assistance has made residential solar more accessible. Still, a subsidy should be treated as part of the project economics—not as a reason to install a system that is larger than the household actually needs.
What Changed in Tamil Nadu’s Solar Subsidy in 2026?
Tamil Nadu introduced an additional state subsidy for eligible residential rooftop-solar consumers under the Tamil Nadu Solar Acceleration Scheme, implemented in convergence with PM Surya Ghar: Muft Bijli Yojana.
The Tamil Nadu Solar Roof Top Portal currently shows the following state subsidy slabs:
₹5,000 for a 1 kW system.
₹10,000 for a 2 kW system.
₹22,000 for a 3 kW system and above.
This amount is added to the Central subsidy available under PM Surya Ghar. The Tamil Nadu portal’s calculator also displays these slabs and combines them with the Central subsidy.tnebltd
Recent reports state that Tamil Nadu’s scheme applies to eligible consumers who registered under the Central scheme from August 5, 2026, subject to the applicable Government Order and scheme conditions. The launch coverage reported combined assistance of ₹35,000 for 1 kW, ₹70,000 for 2 kW and ₹1,00,000 for 3 kW systems.thehindu+1
The exact availability may also depend on the scheme’s application limit, budget and implementation period. One report states that the State scheme is intended to cover up to 1,00,000 consumers by March 2027.
Many customers add up all appliance wattages and install a higher-capacity solar system.
Problem:
- Higher investment cost
- Unused generation if your usage is low
- Longer ROI period
How Much Solar Subsidy Can a Tamil Nadu Household Get?
| Solar capacity | Central subsidy | Tamil Nadu State subsidy | Total possible assistance |
|---|---|---|---|
| 1 kW | ₹30,000 | ₹5,000 | ₹35,000 |
| 2 kW | ₹60,000 | ₹10,000 | ₹70,000 |
| 3 kW | ₹78,000 | ₹22,000 | ₹1,00,000 |
| Above 3 kW | Maximum Central cap applies | State slab cap may apply | No automatic increase beyond applicable caps |
What Is the New ₹22,000 Tamil Nadu State Subsidy?

The ₹22,000 is not a replacement for the Central subsidy. It is an additional Tamil Nadu Government top-up for eligible residential consumers.
The state slabs shown on the Tamil Nadu Solar Roof Top Portal are:
1 kW: ₹5,000.
2 kW: ₹10,000.
3 kW and above: ₹22,000.
So, for a qualifying 3 kW rooftop system:
Central assistance: ₹78,000.
Tamil Nadu assistance: ₹22,000.
Combined possible assistance: ₹1,00,000.
The state subsidy is connected to the Central scheme rather than being treated as an unrelated standalone discount. The PM Surya Ghar guidelines specifically allow a State or Union Territory to provide additional assistance, subject to compliance with scheme guidelines, and state support is to be processed through an integrated portal mechanism.[solarrooftop.pmsuryaghar.gov ]
Tamil Nadu’s portal also includes options related to PM Surya Ghar applicant-detail updates, net-meter agreements and applications for solar rooftop systems.
The ideal way to choose your home solar system in Erode is to look at your EB bill.
- Check your average monthly units consumed (say 450–600 units).
- You can get this by login through TNPDCL portal
- A 1 kW solar system generates around 4 units/day (or 120 units/month).
So, if you use 600 units/month → 600 ÷ 120 = 5 kW solar system fits perfectly.
This simple approach helps you save money while ensuring your solar system matches your real power needs.
Advantages of Right-Sized Solar System
- Reduces electricity bills effectively
- Shorter payback period (usually 3–4 years)
- Long-term performance stability
- Maximizes government subsidy benefits
- Ensures efficient use of solar energy
So, Is It Really a ₹1 Lakh Solar Subsidy?
It can be—but the wording matters.
An eligible residential consumer installing a qualifying 3 kW or higher rooftop solar system may receive up to ₹1,00,000 as the combined Central and Tamil Nadu assistance under the applicable scheme structure.
That does not mean every person who installs solar will receive ₹1 lakh.
The final amount depends on:
Whether the consumer is eligible.
The date and route of application.
Whether the electricity connection is eligible.
Whether the selected vendor follows the approved process.
Whether the system meets technical and equipment requirements.
Whether inspection is completed.
Whether the system is commissioned.
Whether net-metering or the applicable metering agreement is completed.
Whether the required documents and bank details are accepted.
Whether the state scheme’s budget and applicant limits are still available.
It is safer to describe this as up to ₹1,00,000 combined assistance for eligible residential consumers, not as a guaranteed payment for everyone.

How much is the PM Surya Ghar subsidy?
The Central subsidy is ₹30,000 per kW for the first 2 kW and ₹18,000 for the additional 1 kW. The maximum Central subsidy for a residential rooftop system is ₹78,000 under the published structure.solarrooftop.pmsuryaghar.gov
What is the ₹22,000 Tamil Nadu solar subsidy?
It is the highest state subsidy slab under Tamil Nadu’s 2026 rooftop-solar support structure. It applies to eligible 3 kW-and-above residential systems, subject to the applicable scheme requirements and availability.
Can I get ₹1 lakh subsidy for a 3 kW solar system?
An eligible residential consumer may receive up to ₹1,00,000 in combined Central and Tamil Nadu assistance for a qualifying 3 kW system. It is not an automatic guarantee; the application, vendor, equipment, inspection, commissioning, metering and documentation must meet the scheme rules.
Who is eligible for rooftop solar subsidy in Tamil Nadu?
The scheme is intended for eligible residential electricity consumers installing qualifying rooftop solar systems. The consumer must generally have a valid residential connection and complete the required portal, DISCOM, installation and commissioning process.
Is the Tamil Nadu subsidy separate from PM Surya Ghar?
The Tamil Nadu amount is an additional state top-up, but the process is designed to work in convergence with PM Surya Ghar. Tamil Nadu’s portal includes functions connected with PM Surya Ghar applicant information and the state subsidy calculation.tnebltd+1
How is the solar subsidy credited?
After the required verification, inspection, metering and commissioning steps, the eligible Central assistance may be transferred to the beneficiary’s bank account or loan account. The state subsidy follows the applicable Tamil Nadu process, so applicants should check the current portal status and instructions.solarrooftop.pmsuryaghar.gov
Do I need to apply separately for the Tamil Nadu subsidy?
The available portal information indicates an integrated or linked process rather than an entirely unrelated application. Applicants should retain their PM Surya Ghar reference number and follow the current Tamil Nadu Solar Roof Top Portal instructions.tnebltd
Does installing more than 3 kW increase the subsidy?
Not automatically. The Central subsidy is capped at ₹78,000 for residential systems above 3 kW, and the Tamil Nadu subsidy follows its notified slabs rather than increasing indefinitely with capacity.tnebltd+1
How much can a 3 kW solar system save on electricity bills?
The answer depends on generation, consumption, shading, roof orientation, equipment and metering rules. A 3 kW system can reduce grid electricity purchases, but it does not guarantee a zero bill.
Is net metering required?
The applicable metering arrangement is an important part of a grid-connected rooftop-solar project. In many subsidy-linked cases, the DISCOM inspection and meter agreement must be completed before subsidy processing.solarrooftop.pmsuryaghar.gov
How do I apply for rooftop solar subsidy in Tamil Nadu?
Begin through the PM Surya Ghar national portal or the route provided by the official Tamil Nadu rooftop-solar portal. Then complete feasibility, select an eligible vendor, install the system, undergo DISCOM inspection, complete metering and commissioning, and submit the required bank and installation details.
Can tenants apply for rooftop solar subsidy?
Eligibility depends on the electricity connection, permission to use the roof and the applicable scheme rules. A tenant should obtain written permission from the property owner and verify the portal and DISCOM requirements before applying.
Can I claim the subsidy for an already-installed solar system?
Do not assume that an existing system qualifies. The Central guidelines contain conditions relating to application timing, prior subsidy and installation status, so eligibility must be checked before installation or expansion.solarrooftop.pmsuryaghar.gov
A Note Before You Install Solar
Subsidy rules, portal procedures, budget availability and eligibility conditions can change. The figures in this article are updated to September 24, 2026, based on the available official Tamil Nadu rooftop-solar portal and Central scheme information, along with recent announcement coverage.
Before making payment or signing an installation contract, verify the latest details through:

TNPDCL/TANGEDCO or the relevant electricity-distribution office.
The latest MNRE notifications.
The written quotation and scheme-related responsibilities provided by the vendor.
If you are considering rooftop solar in Tamil Nadu, it is worth checking the latest subsidy eligibility and installation requirements before choosing a vendor. Groena Solar can also help homeowners understand the installation process and available options, but the final subsidy decision rests with the applicable government and DISCOM process.
