New to plug-in solar?

Plug-in solar lets anyone generate free electricity — no roof, no permit, no contractor. A single panel on your balcony can meaningfully cut your bill, especially as rates keep rising.

Arizona

Not yet legalUpdated May 30, 2026

Arizona leads the nation in peak sun hours at 6.8 per day. Despite this solar advantage, APS has lobbied against distributed generation. A plug-in solar law would create a simplified pathway that avoids the utility interconnection process entirely.

ℹPanels typically last 25–30 years with a 25-year output warranty. Microinverters carry a 10–25 year warranty depending on brand. Battery modules degrade faster — expect 10–15 years before capacity drops below 80%. The 25-year savings figure above assumes the panel and inverter run for the full window; budget ~$200–$400 for an inverter swap around year 15 if needed.

What a Arizona Law Could Look Like

⚡

Based on neighboring states

Utah (1,200W), Maine (600W), and Virginia (1,000W pending) provide the template. A Arizona law would likely allow 600–1,200W systems to plug into standard household outlets — no permit required.

💸

High rates = strong economics

At Arizona's avg. $0.140/kWh, a 600W system generating ~880 kWh/year saves roughly $123/year. Payback in as few as 6 years at current rates.

🏠

Renters and condo owners

Plug-in solar requires no permanent installation — just an outlet. This makes it uniquely accessible to renters and condo owners who can't get rooftop solar.
