| Avg $/Watt Installed | $3.05 | $2.65 ◆ |
| State Tax Credit | None | 25% / $1000 ◆ |
| Net Metering | modified | modified |

Average 25-Year Savings
California: $58,900 over 25 years (avg payback 7.2 yrs). Arizona: $52,800 over 25 years (avg payback 6.4 yrs).
Verdict: Which State Wins on Solar?
California edges out Arizona on lifetime savings primarily due to more favorable net metering rules.
