What is the payback period for solar in Mesa?
A 7kW system in Mesa costs approximately $21,000 installed (at ~$3/watt). With annual savings of $1,764, the estimated payback period is 11.9 years. Systems typically last 25-30 years, so you can expect 15+ years of free electricity after payback.
How many peak sun hours does Mesa get?
Mesa averages 6.5 peak sun hours per day. This means a 7kW system produces approximately 13,286 kWh per year.
What is NEM 3.0 and how does it affect Mesa solar savings?
NEM 3.0 (Net Energy Metering 3.0) took effect in April 2023 for Salt River Project customers. Unlike NEM 2.0, export credits are now around ~$0.073/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.
What incentives are available for solar in Mesa in 2026?
In 2026, Mesa 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.
