Solar Panels in Oregon: Cost, Payback & ROI (2026)
Is solar still worth it in Oregon after the 30% federal tax credit expired? These pre-computed estimates use NREL PVWatts production data and current 12.5¢/kWh Oregon electricity rates for a typical home using 900 kWh/month.
Section 25D (30% federal solar tax credit) expired December 31, 2025
All numbers below reflect 2026 math with no federal residential credit. State incentives, where applicable, are noted in the section below.

Is Solar Worth It in Oregon in 2026?
Oregon's 12.5¢/kWh rate and 1,200 kWh/kW/year solar resource (in the Portland area; better in central and southern Oregon) create moderate solar economics. Portland General Electric and Pacific Power offer retail-rate net metering. Oregon's Energy Trust provides cash incentives for qualifying solar installations.
For a typical Oregon home consuming 900 kWh per month, our calculation shows a 9.0 kW system needed for 100% offset. At the current national average installed cost of $2.95/W (LBNL Tracking the Sun 2024), that's $26,550 gross before any state rebates. Year-one savings of $1,350 grow each year as electricity rates escalate — the model assumes 2.5%/year (EIA AEO 2024).
The 16.8 years payback period is longer than the national average due to low electricity rates or limited solar resource. Over 25 years — the standard warranty period for most premium panels — a Oregon homeowner following this profile would save an estimated $43,172 total, for a net benefit of $16,622 after recovering the system cost.
