Solar Net Metering in Chennai Explained: Process, Benefits & How to Apply

If you’re planning for solar panel installation in Chennai, one of the most important concepts to understand is net metering.

It directly impacts how much you save from your solar system. But many homeowners still ask:

What is net metering, how does it work in Chennai, and how do you apply for it?

This guide explains everything from the process and benefits to approvals and timelines.

What Is Net Metering?

Net metering is a system that allows your rooftop solar panels to send excess electricity back to the grid.

In simple terms:

• Solar panels generate electricity
• Your home consumes what it needs
• Extra electricity is exported to the grid
• You receive credits for exported units

These credits reduce your monthly EB bill.

How Net Metering Works in Chennai

In Chennai, net metering is managed by TANGEDCO.

Here’s how it works:

Step	Explanation
Solar generates power	Used for your home first
Excess power	Exported to grid
Net meter records	Import & export units
EB bill calculation	Net units billed

This ensures you only pay for the net electricity consumed.
