How Solar Net Metering Works in Your State (2025 Edition)
How Solar Net Metering Works in Your State (2025 Edition) Hild Energy | July 2025 Newsletter
As India pushes toward its renewable energy targets, solar net metering continues to be a game-changer for homeowners and businesses alike. But how it works — and how much you benefit — can vary widely from state to state.
But what exactly is net metering, and how does it work in different states in 2025?
What is Solar Net Metering?
Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. If your rooftop solar system generates more power than your consumption, the excess is fed into the grid, and you get energy credits.
These credits offset the cost of power you draw from the grid during non-sunny hours, helping you significantly reduce your electricity bill.
How It Works – Step-by-Step:
Solar panels produce energy
Your home uses what it needs
Excess power is sent to the grid
Your meter runs backward and earns you credit
You only pay for the net usage
