What to know in Arizona.
Arizona’s distributed-generation interconnection statute directs an applicant to submit a complete application to the utility at the point of interconnection. Review the statute’s approval, timing and waiver provisions with that utility.
UniSource explains that Arizona Corporation Commission interconnection rules govern its rooftop solar connections and may require design changes or export restrictions.
UniSource’s instructions describe its territory and regulated-utility rules. Confirm the equivalent tariff with APS, SRP, a cooperative, or your municipal provider.
Who provides electricity here?
Narrow possible delivery utilities by ZIP or confirm yours
Find the delivery utility on your electric bill first. A retail supplier or on-site solar seller may be a different company; your delivery utility handles the local grid connection.
Includes electric-company maps. City, district and tribal utility service is outside ACC electric ratemaking jurisdiction; confirm boundary addresses.

Source: EIA-861 final 2025 detailed data · Reporting year 2025. Names and reported counties are historical survey data, not a live address lookup. A county can have several providers, and a listing does not mean every resident can choose it. Small/territory-only reports may not identify residential service separately.
Credits, rebates, and other opportunities.
Check the program’s scope before comparing savings: a tax exemption, equipment rebate, loan and electricity-export payment provide different benefits. Funding, utility territory, income, equipment and installation dates can limit eligibility. Amounts below are not added together or deducted from product prices.

Credit for Solar Energy Devices
Arizona Department of Revenue · Solar
Nonrefundable individual income-tax credit for qualifying purchased solar devices installed at an Arizona residence.
- Benefit
- Current statute: 25% of device cost, with a $1,000 maximum credit and $1,000 cumulative cap for the same residence; unused credit may carry forward up to five years.
- Who may qualify
- Individual taxpayer installing a qualifying device at an Arizona residence. Purchased devices qualify; leases/PPAs do not qualify under the published instructions.
- Before applying or buying
- Retain installation and compliance records and use the tax-year form. Confirm current-year requirements before relying on the credit.
No matching records in this reviewed selection. Check the official program sources for more options.
The state solar tax credit is distinct from federal credits and utility export compensation. This is not a cash rebate or an eligibility guarantee. This is a curated starting list, not every local incentive or a guarantee of available funding.
Federal programs in every state
The federal rules below apply nationally. State-administered federal rebates still require the local program to be operating and your project to meet its conditions.
Residential Clean Energy Credit (25D)
Closed / endedNot available for new property placed in service after December 31, 2025. Do not assume a federal 30% credit for a new 2026 solar, wind, geothermal or battery installation.
IRS: Residential Clean Energy CreditEnergy Efficient Home Improvement Credit (25C)
Closed / endedThe federal home-efficiency credit, including qualifying heat-pump improvements, ended for property placed in service after December 31, 2025.
IRS: Energy Efficient Home Improvement CreditHOMES / High-Efficiency Electric Home Rebates
Eligibility / funding conditionsFederally funded home-energy rebates operate through participating local administrators. Check the state program’s launch, current funding, eligible measures and application requirements. This is not a blanket rooftop-solar rebate.
DOE: Home Energy Rebates ProgramWeatherization Assistance Program
Eligibility / funding conditionsIncome-eligible households may receive approved home-weatherization services through local agencies. This is assistance delivered through a program, rather than an automatic reimbursement for equipment you buy.

Permits and electrical codes.
Use your city or county permit office. Phoenix, for example, publishes a residential SolarAPP+ process and identifies a separate fire permit; that example is not a statewide permit rule.
Use the adoption authority linked below to check the effective date and amendments. The newest published NEC edition is not automatically the edition adopted for your project.
Before ordering equipment.
Two conversations. Keep their answers separate.
Track permits and interconnection in a project
- Confirm the permit authority
Ask the city, county, or state electrical office which building, electrical and fire-code editions and amendments apply to this address. Request the solar/ESS permit checklist and inspection sequence.
- Confirm the utility process
Give the serving utility your proposed capacity, inverter model and operating mode. Ask which interconnection application, tariff, export limits, meter changes and written operating authorization apply.
- Document the exact equipment
Collect model-specific certificates, installation manuals, a one-line diagram, site/roof plans, and the battery/inverter pairing if storage is proposed. Check them with the permit authority and utility before ordering.
For the general permitting and inspection process: DOE: Permitting and Inspection for Rooftop Solar .
UL, NEMA, and system acceptance.
Different evidence, different scope.
Check the exact model and approved system configuration. A UL 1973 battery listing or UL 9540A fire-test report does not, by itself, establish UL 9540 certification of a complete storage system.
Open the UL & NEMA referenceScope and system-level certification: UL Solutions: Energy Storage System Testing and Certification .
