Mesa homeowners on Salt River Project pay an average of $185/month at 12.0¢/kWh (Tier 1) and 14.0¢/kWh (Tier 2). With 6.5 peak sun hours per day, a properly sized system can offset 80-90% of your usage, cutting the average bill from $185 to ~$11/month.

What Drives Savings in Mesa?

• Salt River Project rate structure: At 14.0¢/kWh for Tier 2, every kWh your panels produce offsets your most expensive grid usage first. That is where the math gets compelling.
• 6.5 peak sun hours: Above-average sun exposure makes every panel more productive.
• NEM 3.0 (since April 2023): Export credits are now ~~$0.073/kWh, so self-consumption matters most. Size your system for your daytime usage, not maximum export.
• Rate escalation: Salt River Project rates have increased 31% (2014-2024). Each year you wait, your baseline bill grows, making the solar investment more valuable in hindsight.
