Your rebate comes in STCs

The image features a vector image of a piggy bank and text which explains that calculating STC rebates varies depending on your geographic location and the size of your system.

The solar panel rebate, or financial incentive (correct government term), is issued in the form of Small- scale Technology Certificates, commonly referred to as STCs. Each STC carries a monetary value that fluctuates between $37 – $40, for the 2023 calendar year the STC price averaged $40.

Location and system size

When you purchase a solar system, you’ll receive a certain number of STCs according to the size of your solar system and your location. The total value of these certificates is your solar panel rebate amount.
