Is Plug-In Solar Legal in Arizona?

Strong sun, check utility   Avg rate ~15¢/kWh

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.
