Is plug-in solar legal in Arizona? (2026)
Arizona has no law that specifically addresses plug-in solar as of 2026-09-20. That is not the same as illegal. It means no statute answers the question either way, so your utility's rules are the ones to check.
Not addressed
Arizona has no law specifically addressing plug-in solar as of September 2026; two 2026 bills were held in committee.

Research notes
HB 2843 ('portable solar power devices; requirements', introduced 2026-01-15) and SB 1606 ('plug in solar energy; requirements', introduced 2026-01-29) both show FinalDisposition 'Held in Committees' on the official azleg.gov bill-status API for the 57th Legislature, 2nd Regular Session — dead. SB 1419 (Chapter 175, signed 2026-06-19, 'solar energy; inspection; contractors', amends ARS 44-1761 to 44-1763) is cross-referenced by the legislature but its chaptered text contains no portable/plug-in provisions (grep of chaptered PDF), so it does not legalize plug-in solar. Watt figures (1,200W) for HB 2843 come from news and are not verified.

If you rent
Without a state law, you need two yeses: your landlord’s, and your utility’s. Start with the utility, because a landlord will ask whether it’s allowed. Ask these three questions and get the answers in writing:
- “Do you have an interconnection requirement for a plug-in solar device under 1,200 watts with a UL-listed inverter?”
- “If it never sends power back to the grid, does that change your answer?”
- “Can you send me that in writing, or point me to the tariff section?”
If you get a written answer, send it to hello@mlighthouse.com. We’ll add it to this page with the utility named and you left out.
If you own your home
You have the same utility question as a renter, and one more option: a conventional rooftop or ground-mount system goes through your utility’s standard interconnection process instead. It costs more and takes longer, but the rules are written down.
What Arizona's largest utilities say
What each utility's own tariff or interconnection page says about generation a customer connects on their side of the meter.
Arizona Public Service (APS)
Even a small inverter system goes through an interconnection application, the Level 1 Super Fast Track for 20 kW or less. The page does not mention plug-in or portable solar.
“R14-2-2617 Level 1 Super Fast Track – A Customer interconnecting an inverter-based GF with a Maximum Capacity of 20 kW or less, which only uses Certified Equipment.”
aps.com ↗Salt River Project (SRP)
SRP requires every customer connecting a solar system to its grid to sign an interconnection agreement, with no size exemption stated. The page does not mention plug-in or portable solar.
“SRP requires that all customers that will interconnect their solar electric system to SRP's electrical distribution system sign an agreement that outlines the interconnection rules and requirements.”
srpnet.com ↗Tucson Electric Power (TEP)
TEP says solar construction may start only after it approves the application. The page does not mention plug-in or portable solar.
“Construction of solar projects may only begin after approval from TEP.”

Investigates disputes with the utilities the Commission regulates. It cannot help with complaints about solar companies or municipally owned utilities.

What an 800 W kit makes in Arizona
A railing-mounted panel hangs close to vertical, so it makes less than a tilted rooftop panel. These figures use a vertical panel on purpose.

Questions about Arizona
Is plug-in solar legal in Arizona?
Arizona has no law that specifically addresses plug-in solar as of 2026-09-20. That is not the same as illegal. It means no statute answers the question either way, so your utility's rules are the ones to check.
How much could an 800W kit save in Arizona?
About $110 a year, before the kit's cost, for an unshaded 800W panel on a south-facing railing at 15.46¢/kWh. That assumes you use 80% of what it makes. Run the calculator for your own numbers.
