Installing rooftop solar has become more affordable for households in Tamil Nadu. Under the PM Surya Ghar: Muft Bijli Yojana along with the Tamil Nadu Government’s additional solar subsidy, eligible residential consumers can now receive total financial assistance of up to ₹1,00,000 for installing rooftop solar.
How Much Solar Subsidy Can You Get in Tamil Nadu?
Tamil Nadu households can receive both Central and State Government assistance.
Solar System Capacity | Central Subsidy | Tamil Nadu Subsidy | Total 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 | ₹78,000 max | ₹22,000 max | ₹1,00,000 max |
For an eligible 3 kW rooftop solar system, a household can therefore receive up to ₹1 lakh in total financial assistance.
Eligibility Criteria
Must be an Indian citizen and a domestic electricity consumer.
Must own a house with a roof suitable for solar panels.
Must have a valid electricity connection and not have claimed other solar subsidies
How Does the ₹1 Lakh Subsidy Work?
The total assistance consists of:
Central Government subsidy: Up to ₹78,000 under PM Surya Ghar.
Tamil Nadu Government top-up: Up to ₹22,000.
Together, these can provide eligible households with up to ₹1,00,000 in assistance.
According to the Tamil Nadu Solar Rooftop Portal, both subsidies are provided through Direct Benefit Transfer to the beneficiary’s bank account, subject to the scheme's eligibility and completion requirements.
Who Can Apply?
The subsidy is primarily available for eligible residential rooftop solar installations in Tamil Nadu.
Applicants must follow the scheme requirements, complete the installation and meet the conditions specified by the authorities.
The Tamil Nadu portal states that eligible systems must use compliant solar modules and approved vendors, while the state subsidy is released after installation, net metering, commissioning and Central Financial Assistance disbursement.
How to Apply for Rooftop Solar Subsidy in Tamil Nadu
Residential consumers seeking the subsidy should first register and apply through the PM Surya Ghar National Portal.
After receiving the National Portal reference number, the consumer proceeds through Tamil Nadu's Unified Solar Rooftop Portal and completes the required application and installation process.
The process generally includes:
Register on the PM Surya Ghar National Portal.
Enter your Tamil Nadu electricity connection details.
Apply for rooftop solar.
Select an eligible solar vendor.
Install the rooftop solar system.
Complete inspection and net-metering procedures.
Complete commissioning.
Receive the eligible Central subsidy.
After meeting Tamil Nadu scheme requirements, receive the applicable State subsidy.
Why Is This a Good Opportunity for Tamil Nadu Homeowners?
Up to ₹1 Lakh Government Support
The combination of Central and Tamil Nadu Government assistance can significantly reduce the initial cost of installing rooftop solar.
Lower Electricity Bills
Solar panels generate electricity during the daytime, helping reduce the amount of electricity a household needs to draw from the grid.
Make Better Use of Your Rooftop
An unused rooftop can be converted into a clean electricity-generating asset.
Long-Term Savings
A properly installed rooftop solar system can continue producing electricity for many years. Tamil Nadu's rooftop solar FAQ states that a grid-connected rooftop solar plant typically has a lifespan of around 25 years.
Cleaner Energy for Tamil Nadu
Installing rooftop solar helps households reduce their dependence on conventional power sources while supporting Tamil Nadu's transition toward renewable energy.
Example: 3 kW Solar System in Tamil Nadu
For an eligible 3 kW residential rooftop solar system:
Central subsidy: ₹78,000
Tamil Nadu Government subsidy: ₹22,000
Total Government Assistance: ₹1,00,000
This can considerably reduce the amount a homeowner needs to invest from their own pocket.
Turn Your Rooftop Into a Source of Savings
With Government support of up to ₹1 lakh, this can be an attractive time for eligible Tamil Nadu homeowners to consider rooftop solar.
Before installation, homeowners should check their electricity consumption, available rooftop area, suitable system capacity, vendor eligibility and the latest scheme requirements.
