Balcony Solar in Arizona
Arizona had two plug-in solar bills in 2026 — HB 2843 and SB 1606 — both requiring NRTL certification and NEC compliance. Both were held or killed in committee, so no law took effect.
Reviewed August 6, 2026 against primary sources. Laws change — the sources below let you re-check.
Did Arizona's bill require UL 3700?
No — the bill does not name UL 3700.
Both bills required certification by a nationally recognized testing laboratory plus NEC compliance (primary text read). Neither names UL 3700.
Why this matters: “certified by UL” names an organization; “certified to UL 3700” names a plug-in-PV standard. They are not the same claim. Full explainer →
What's still unsettled
- Both bills held/killed in committee (Feb 2026).
Before you buy in Arizona
This bill did not pass, so there is no plug-in-solar-specific law in Arizona right now — the state's default utility and electrical rules apply. And regardless, no plug-in kit sold in the US carries UL 3700 yet. What "UL 3700 certified" really means →
