Rooftop solar for independent houses
Older localities like Mylapore, Adyar and Anna Nagar have many independent houses with clear roof space. Installers design systems that fit the roof and handle the TNPDCL net metering application.

Commercial and industrial solar
Offices on OMR and factories in Guindy have high daytime consumption and large roofs. Larger systems reduce electricity bills and can be designed for on-grid or hybrid operation.

Where rooftop solar makes sense in Chennai
Independent houses in Adyar, Mylapore, Anna Nagar and Kodambakkam usually have enough roof space for a 2–3 kW system. Apartments on OMR, Velachery and Sholinganallur can use common rooftops if the society agrees. Commercial buildings on OMR and industrial units in Guindy are strong candidates for larger installations because of high daytime consumption.

Summer demand and solar in Chennai
Chennai's electricity consumption rises sharply in summer as air conditioning use increases. April 2026 saw an 8.9% growth in national electricity consumption, and Chennai's hot, humid weather means many homes run ACs for long hours. A rooftop solar system offsets a large part of this daytime load, which is when solar generation is highest.
Questions Chennai residents ask about rooftop solar
How much subsidy can I get for rooftop solar in Chennai?
Under PM Surya Ghar Muft Bijli Yojana, the central subsidy is ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW. The maximum is ₹78,000 for a 3 kW or larger system. You apply through the National Portal and select a vendor there.
Which DISCOM handles net metering in Chennai?
TNPDCL (formerly TANGEDCO) processes residential rooftop solar applications in Chennai. They do the feasibility check and install the net meter after the system is commissioned.
Is rooftop solar worth it for an apartment in Chennai?
It depends on the society's roof space and agreement. Apartments on OMR and Velachery can install a common system for shared areas, but individual flats usually cannot get net metering unless the roof is allocated to them. Talk to your resident association first.
What is the price of a 3 kW solar system in Chennai?
A 3 kW on-grid residential system with installation starts between ₹2,15,000 and ₹2,47,000. The final price depends on the roof, inverter brand and installer. The PM Surya Ghar subsidy reduces the upfront cost by up to ₹78,000.
How long does it take to get the subsidy after installation?
After the installer submits the redemption request on the National Portal, the average processing time is around 15 days, provided all credentials are entered correctly.
Can I get a loan for rooftop solar in Chennai?
Yes. Nationalized banks offer collateral-free loans at a concessional interest rate of repo rate plus 50 basis points, currently 5.75% per annum, with a tenure of 10 years.
