What is NEM 3.0 and how does it affect Prescott solar savings?
NEM 3.0 (Net Energy Metering 3.0) took effect in April 2023 for Arizona Public Service customers. Unlike NEM 2.0, export credits are now around ~$0.075/kWh instead of near-retail rates. This means self-consumption — using solar power as it is produced — is more valuable than exporting to the grid. Pairing solar with a battery shifts more production to evening hours when you would otherwise buy from the grid.

In 2026, Prescott homeowners can benefit from: California's property tax exclusion for solar, the SGIP battery incentive, and the California Solar Rights Act (HOAs cannot block installation). Note: the federal residential solar tax credit (Section 25D) expired December 31, 2025. The commercial Section 48E credit remains active for PPAs and business installations.
