Arizona Net Metering Policy

Net billing (export at lower than retail)

APS and other Arizona utilities shifted from full retail net metering to net billing arrangements. Exported solar is credited at 60–80% of retail. TOU rates are common — battery pairing is increasingly important.

Arizona Solar Incentives

Available in addition to any utility rebates. Federal 25D credit is $0 for homeowner-owned systems from 2026.

  • State income tax credit (25%, up to $1,000)
