A snapshot of what solar actually costs and pays back in Oregon right now, plus every calculator on this site pre-loaded with Oregon's numbers.
At Oregon's average residential electricity rate of $0.13/kWh and 4.0 peak sun hours per day, a standard 6kW residential system produces roughly 7,008 kWh a year. Installed at an estimated $2.90/watt, that system runs about $17,400 before incentives, with a simple payback around 19 years at full retail-rate value. Your real number depends heavily on your actual usage and roof — run it precisely in the Solar Panel Calculator, pre-loaded with Oregon's defaults.
Oregon: Statewide net metering at retail rate. That's roughly a 100% export credit relative to the retail rate in our model — see the exact math for your own production and consumption in the Net Metering Calculator.
The federal residential tax credit (Section 25D) expired for owned systems installed after December 31, 2025 — see our 2026 federal tax credit guide for the full picture. At the state level: Oregon's Solar + Storage Rebate Program offers a rebate, with a larger amount for income-qualified households — check current availability. Check the Solar Tax Credit & Incentive Calculator for a worked example, and verify current program status with a database like DSIRE before budgeting around any specific number.
