What this means for you
✓ What you can do
- Apply for interconnection like any small generator (Level 1 Super Fast Track: inverter-based <=20 kW certified equipment, 14-day review), Only if in approved tariff (R14-2-2614(B)(3)); amounts not retrieved.
- Use portable panels with a power station, never connected to house wiring, with no permission at all.
- Install conventional rooftop or ground-mount solar through the standard interconnection process.
✕ Not yet / not allowed
- Plug a grid-tied kit into an outlet without an interconnection agreement; it can breach your service terms.
- Expect a permit or wiring exemption; none exists without a law.
- Count on SB 1606 this year: Did not advance (2026); deferred to 2027.
What the rules say
Arizona's 2026 bills died after utilities objected; APS/SRP interconnection rules still apply.
What happened in 2026. SB 1606: Did not advance (2026); deferred to 2027.
Before you plug in: Arizona checklist
- The rule that applies is Arizona Corporation Commission (APS, TEP, UNS, co-ops); SRP self-governed's interconnection process: A.A.C. R14-2-2601 et seq. (2020).
- A plug-in kit falls in the smallest tier (Level 1 Super Fast Track: inverter-based <=20 kW certified equipment, 14-day review). Only if in approved tariff (R14-2-2614(B)(3)); amounts not retrieved.
- Permits: No statewide NEC; municipal permits/inspection required for PTO.
- Only consider kits with a UL 1741-listed inverter (UL 3700 preferred); a non-listed inverter will not be approved anywhere.
- What exports are worth: Net billing at Resource Comparison Proxy (APS ~5.55 c, TEP ~4.6 c, SRP ~1.9 c/kWh) after interconnection.
- If approval is slow or costly, a portable panel and power station (never connected to house wiring) needs no permission.
- Watch SB 1606: Did not advance (2026); deferred to 2027.
The rules in detail
Arizona has no statute specific to plug-in solar (the only bill so far is HB 2843 / SB 1606). Average residential electricity price: 15.38¢ per kWh (EIA, July 2026).
- Utilities: Vote delayed after utility opposition (NPR Mar 2026).
Your utility's rules in Arizona
No utility in Arizona publishes a rule that specifically allows or bans outlet-connected generation, so the general interconnection agreement is what applies. Here is what the largest residential utilities say and require.
| Utility | Residential customers | Published position on plug-in kits |
|---|---|---|
| Arizona Public Service | 1,256,120 | No specific statement. |
| Salt River Project | 1,053,407 | No specific statement (self-regulated political subdivision). |
| Tucson Electric Power | 412,747 | No specific statement. |
| UNS Electric | 95,191 | No specific statement. |
Interconnection terms for a sub-1.2 kW system
| Regulator | Arizona Corporation Commission (APS, TEP, UNS, co-ops); SRP self-governed. |
|---|---|
| Governing rule | A.A.C. R14-2-2601 et seq. (2020). |
| Smallest tier | Level 1 Super Fast Track: inverter-based <=20 kW certified equipment, 14-day review. |
| Application fee | Only if in approved tariff (R14-2-2614(B)(3)); amounts not retrieved. |
| Electrician / permit | No statewide NEC; municipal permits/inspection required for PTO. |
| Export compensation | Net billing at Resource Comparison Proxy (APS ~5.55 c, TEP ~4.6 c, SRP ~1.9 c/kWh) after interconnection. |
| Electrical code | None statewide (local adoption). |
In practice
- Phoenix metro splits between APS (ACC rules) and SRP (own rules, ~1.9 c export credit).
- No statewide electrical code: permittability depends on city/county NEC edition.
