Net Metering in India — Complete Guide
Net metering allows you to export unused solar electricity to the grid and get credits on your electricity bill. It's available across most Indian states.
How Net Metering Works
- Your solar panels generate electricity during the day
- Your home/business uses what it needs
- Excess electricity flows back to the DISCOM grid
- Your meter runs backwards, crediting units to your account
- At month-end, you pay only for the NET units consumed (imports minus exports)
Billing Under Net Metering
Example:
- Monthly consumption: 500 units
- Solar generation: 400 units
- Export to grid: 150 units (surplus after self-consumption)
- Net import from grid: 500 - 250 self-consumed - 150 export credit = 100 units
- Bill: 100 units × ₹8 = ₹800 instead of ₹4,000 — 80% saving!

Gross Metering vs Net Metering
Some states are moving to gross metering where all generation is exported at a fixed rate. Check your state's current policy before applying.
