TANGEDCO Net Meter Application After Solar Panel Installation in Chennai

The net meter application is the step between finishing solar panel installation in Chennai and actually seeing a lower EB bill. It is filed with TANGEDCO after the physical installation is complete, and it results in a bidirectional meter that records both the power you draw and the power your panels export.

Who files the application?

In most solar panel installation in Chennai projects done through a full-service installer, the installer files the net meter application on behalf of the homeowner. The homeowner signs the application form and provides a few documents. If the installer hands you the form and tells you to file it yourself, that is a reduced-service arrangement — not necessarily wrong, but worth knowing before you sign the installation contract.

Documents required

TANGEDCO's net meter application typically requires: a copy of the latest EB bill (showing consumer number and sanctioned load), the homeowner's ID proof (Aadhaar or passport), a copy of the solar inverter datasheet, an installation photograph showing the panels on the roof, the single-line diagram of the system, and the signed net metering agreement form. The exact document list can vary slightly by TANGEDCO sub-division; your installer should know the local requirements.

Where to file for Madipakkam

For solar panel installation in Madipakkam, the application goes to the TANGEDCO sub-division office covering your area. Madipakkam and Medavakkam properties typically fall under the O&M (Operations and Maintenance) division for south Chennai. The installer who regularly files in this area knows the contact person and expected timelines — which matters when following up on a delayed meter swap.

What happens after filing

After the application is acknowledged, TANGEDCO schedules a site inspection. The inspector verifies the system matches the application documents, confirms the inverter is of approved make, and checks that earthing and protection devices are in place. After inspection, the meter swap is scheduled. In Chennai, the inspection-to-swap timeline runs 3–8 weeks depending on the sub-division's workload.

What to do if the application stalls

If 10 weeks have passed without a meter swap, follow up directly with the sub-division office. The installer should be doing this as part of their scope, but if they are not, you can visit the office with your acknowledgement number. For solar panel installation in Chennai through ZeroEB, net meter follow-up is tracked until commissioning is confirmed. When the EB bill actually changes explains what to expect once the meter is in.
