Understanding Net Metering

What is net metering? Net metering is a billing mechanism that credits solar owners for electricity exported to the grid. When your panels produce more than you use, the excess flows to the grid and your meter runs backward.

Compensation: Full retail rate. The credit rate determines how quickly you recover your investment.

Capacity limit: 1 MW limit. Systems larger than the capacity limit may be subject to different rules.
