Yes. Most utilities will pay you for the excess energy your system produced but that your home did not consume, and this typically happens after a year of use. Each month, your excess energy is giving you a credit going toward your use in following months. If you still end up with a credit at the end of a year, you are thenĀ paid for that excess energy that you supplied to the grid.

During the year the energy you produce is worth exactly what you pay for it, but when your utility pays for the annual excess, they pay you based on a lower wholesale rate. You could equate this to the generation charge on your bill. Be aware then, that you are paid a smaller amountĀ for this excess, and it is usually not a worthwhile investment to install extra panels just to make extra money.

These policies vary among utility companies, so consider verifying the arrangements with yours for a more specific answer.
