How to check a solar quote in Phoenix

• Divide your quote by system size in watts. Phoenix quotes on EnergySage average $2.28/W; a typical 13.9 kW system there is quoted $26,915–$36,415 before incentives.
• Ask which utility credit the savings estimate uses. Power you send to the grid is credited at: Arizona Public Service 5.55¢/kWh; Salt River Project 3.45¢/kWh.
• Ask whether the offer is a purchase, loan, lease or PPA. In these records Freedom Forever, Sunrun leased or signed PPAs on 30% or more of systems.
• Look up the company's contractor license with the Arizona Registrar of Contractors before signing.
• Paste the price and size into the quote checker or follow the six-step quote check.

Incentives and rules for Phoenix homeowners

• Federal tax credit: the 30% Residential Clean Energy Credit is not available for property placed in service after December 31, 2025 (IRS).
• Credit for Solar Energy Devices (A.R.S. 43-1083): 25% of device cost, max $1,000 per residence, unused credit carried forward up to 5 years, no sunset in statute
• Arizona Public Service: Effective September 1, 2026 in ACC Decision No. 82122
• Salt River Project: Other SRP solar plans credit exports differently (E-15 nets at retail price, closes November 2029)
• Property tax: A.R.S. 42-11054(C)(2): solar energy devices designed to produce solar energy primarily for on-site consumption are considered to add no value to the property.
• Sales tax: A.R.S. 42-5061(M): amounts received from sales of solar energy devices are deducted from the transaction privilege tax base; the retailer must be registered as a solar energy retailer.
• Selling power back: Net billing. Utilities regulated by the Arizona Corporation Commission (APS, TEP) credit exports at the Resource Comparison Proxy (RCP) rate, locked for 10 years from interconnection; the rate for new customers can drop by no more than 10% per year. SRP is not ACC-regulated and sets its own export credit.
