The TANGEDCO net-metering process, step by step
- 1
Apply on the national rooftop-solar portal
Register with your electricity account number and choose TANGEDCO as your DISCOM. This starts your subsidy application.
- 2
TANGEDCO feasibility check
TANGEDCO verifies your connection and sanctioned load. Systems up to 3 kW skip this separate approval step.
- 3
Install through a registered vendor
A registered installer sets up your system and files the net-metering request with TANGEDCO on your behalf.
- 4
Inspection & bidirectional meter
TANGEDCO inspects the installation and fits a bidirectional (net) meter that records both the power you import and the power you export.
- 5
Commissioning & net metering activated
Once commissioned, your exported units begin offsetting the units you draw from the grid.
- 6
Subsidy credited to your bank
The central rooftop-solar subsidy is transferred directly to your bank account after commissioning — it is not deducted upfront.
Typical timeline
Most homeowners see TANGEDCO approvals in a few weeks, with the subsidy credited about a month after commissioning. Timelines vary by circle and sanctioned load.

How long does TANGEDCO net metering take?
Typically a few weeks for approvals, plus about a month for the subsidy to be credited after commissioning. It varies by circle and sanctioned load — treat TANGEDCO's portal as the source of truth for current timelines.
Do I need feasibility approval for a small rooftop system?
For systems up to 3 kW the separate technical-feasibility approval is generally waived, which speeds up the whole process.
Which meter do I need for net metering?
A bidirectional (net) meter that records both the power you import from and export to the grid. TANGEDCO installs it during the inspection step.
Does the subsidy come through TANGEDCO?
