Under full net metering every kWh you export earns the retail price. Under net billing, exports earn a lower credit, so the share you use at home matters.

How it works

Savings = kWh used at home × retail price + kWh exported × export credit.

Example: 10,936 kWh a year with 30% used at home saves $1,056, against $1,989 under full net metering.

Common questions

What is net metering?

A billing rule that credits each kWh your panels send to the grid at the retail price, so the meter in effect runs backward.

What is net billing?

A rule that credits exports at a lower rate, often near the utility's avoided cost. Using more of your solar at home, or adding a battery, raises savings.
