Do I need utility permission in Arizona?

It depends on your state's rules and your utility. The safe path in Arizona is to use a UL-listed (UL 3700) microinverter and check your utility's interconnection policy (major utilities here include APS, SRP) before you install; see the status for Arizona above for specifics.

Quick answer: Plug-in (balcony) solar is legal to install in Arizona, but there is no plug-in-specific state law as of June 2026 — it falls under your utility’s standard interconnection rules. Average residential electricity rate is around 15¢/kWh. Confirm wattage limits with your utility before buying.

Excellent solar resource. Utilities like APS and SRP set interconnection terms; plug-in rules aren't explicit, so confirm before buying.

Before you buy in Arizona

Call your electric utility and ask: (1) do they allow small plug-in / behind-the-meter grid-tied solar, and (2) is any notification or interconnection form required? Stay within the wattage they specify, use a UL-listed microinverter, and keep written confirmation.

Then estimate your numbers with our savings calculator (pre-loaded with Arizona's rate).
