Solar panels in Oregon: cost, payback and the rules that matter

Four facts that decide solar in Oregon
1. The sun. One kilowatt of panels makes about 1,244 kWh a year in the median Oregon city, from 1,187 in Portland to 1,452 in Bend.
2. The price of electricity. Every kWh your panels make is worth what you would otherwise pay: 15.4¢ in Oregon today.
3. What your utility pays for exports. Most Oregon utilities still credit exported solar close to the retail rate, but rules differ by utility and change often.
4. Incentives. The 30% federal Residential Clean Energy Credit (IRC §25D) ended for systems whose installation is completed after December 31, 2025 (One Big Beautiful Bill Act, P.L. We don't know of a statewide income-tax credit for home solar in Oregon.
