Sunwon Solar › Net metering
Net metering for your rooftop solar
A net meter counts the units your solar sends to the grid, so the EB bills you only for what you take above that. We handle the application for you.
How net metering works, in one minute
During the day your panels make power. Your home uses what it needs. The extra flows out to the grid through a special meter that counts both directions — the net meter. In the next bill, the EB subtracts the units you sent from the units you took. If you sent more than you took, the extra is carried forward as credit.
Who approves it
- Puducherry: the Electricity Department. We file the feasibility, inspection and net-meter application for you.
- Tamil Nadu: TNPDCL (Tamil Nadu Power Distribution Corporation). Same — we handle the DISCOM steps.
From inspection to a working meter
- We register you on the PM Surya Ghar portal and apply for feasibility.
- Your DISCOM confirms your connection can accept the system.
- We install your system on a date agreed with you, confirmed in writing.
- DISCOM inspects the installation and fits the net meter.
- Your meter now counts both directions. Your savings start here.
- We file the subsidy claim; the money goes to the bank account named on the EB connection.
Questions people ask
How long does the net meter take to get fitted?
It varies by DISCOM and area; usually two to four weeks after your installation is ready for inspection. We follow up so you don't have to.
Do I have to apply myself?
No. We fill the PM Surya Ghar portal, the DISCOM feasibility and the net-meter application for you, and send you a WhatsApp update at every step.
What happens if I send more units than I use?
In most cases the extra is carried forward as credit on your bill. At year-end any remaining credit is settled per your DISCOM's rules.
