What the law says now
SB 1606 remains a proposal, with the Arizona legislature listing its latest action as deferred to the 2027 session. Bright Saver’s tracker reports the same status. The bill would define devices intended primarily to offset your electricity consumption, with a limit of 1,200 W of AC inverter output—not panel DC power.
The proposed text says a public power entity may not require a customer to “Obtain approval before installing or using the portable solar generation device.” It would also prohibit fees and requirements for additional controls beyond those integrated into the system. These exemptions have not taken effect.
The bill would require the device to meet the most recent National Electrical Code, be certified by a nationally recognized testing laboratory, and be listed and labeled in compliance with a national standards institute. It also requires a feature preventing the system from energizing the building’s electrical system during an outage.
Your options before a law passes
A solar-charged portable power station can supply devices without connecting solar generation to your home’s grid-connected electrical system. EcoFlow says its DELTA Pro 3 supports solar charging. Homeowners can also seek rooftop solar quotes rather than wait for the plug-in proposal.
Before buying a grid-connected kit, ask your utility what approval and equipment requirements apply. If you rent or have an HOA, check property permissions separately; the proposed utility exemption should not be treated as landlord or HOA permission. Check certification documentation rather than assuming a kit meets the proposed requirements.
For a hypothetical 800 W kit with 800 W of panels and an 800 W inverter limit, vertical and facing south near Arizona’s population center, the calculator gives 870 kWh in a typical year. With a 164 W home base load, 475 kWh is used at home and 395 kWh goes to the grid. At 15.44 cents/kWh, the modeled value is $73 a year, with exports valued at zero—not authorization to connect.
