The short answer

For most Arizona homeowners planning to stay 8+ years, rooftop solar pencils out clearly positive over 20 years.

The 4 things that actually determine "worth it"

Electricity rate. Arizona: 15.48¢/kWh. National avg: 18.83¢. You’re 18% below average — cheap grid electricity makes payback slower.
Sunshine. Arizona: 6.5 peak sun hours/day. National avg: 4.5. Above average sun — production per kW is high.
Install cost in Arizona. $2.60/watt (state avg). Cheaper than national $3.00/W — competitive installer market here.
Incentive stack. Federal ITC 30% applies universally. 25% state tax credit up to $1,000 Net metering: Replaced by 'net billing' — exports valued at utility avoided cost (~3... Full incentive breakdown →

Where Arizona ranks nationally

Across all 51 states, Arizona ranks #9 of 51 by 20-year net solar savings (1 = best). The top states are dominated by combinations of high electricity rates and high sunshine (CA, HI, MA, NY, CT). The bottom are cheap-power / cloudy-sky states (WA, OR, ID, ND).

Break-even analysis

Your solar system in Arizona needs to save $10,920 in electricity to pay for itself. At $1,719/year savings, that’s 6.4 years. Panels are warrantied for 25 years and typically last 30+ — meaning 23.6+ years of free electricity after breakeven.

Common objections addressed

“What if I move before payback?”

Homes with paid-off solar typically sell for ~$15,000-$25,000 more than comparable homes without. If you owe money on the panels (loan), the sale is more complex. Cash or fully-paid-off systems recover most or all of the remaining "unused" value at sale.

“Won’t rates drop?”

U.S. residential electricity rates have risen ~4%/year over the past decade. Even if rates flatline, the payback above holds. If rates rise, your solar looks better in retrospect.

“What about hail / storms?”

Solar panels are rated for 1-inch hail at 50 mph. Damage claims are covered by homeowner’s insurance in almost all cases (verify with your carrier).
