Net metering allows you to send excess solar electricity back to the grid. Whatever power you send to the electricity department is adjusted in your monthly bill.

✔ Import: Electricity you use from the grid.
✔ Export: Surplus solar energy you send to the grid.
✔ Net Bill: Import – Export = Final Bill

With proper net metering, your monthly bill can reduce up to 80–100% depending on your solar system size.
