Oregon Solar Guide 2026
Everything Oregon homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.
Quick answer
Oregon solar economics depend mainly on 4.2 average peak sun hours, an estimated $2.85/W installed cost, 12.0¢/kWh electricity, and the state's current net-metering rules.

Key fact about Oregon solar
Oregon's west side has lower sun hours than most states, but full retail net metering and the Solar + Storage Rebate program make it viable. East of the Cascades has Phoenix-like sun hours.

Oregon Net Metering Policy
Full retail net metering
Oregon requires full retail net metering under ORS 757.300. PGE and Pacific Power must credit excess at retail. Annual settlement — unused credits paid at avoided cost at year-end.
Oregon Solar Incentives
Available in addition to any utility rebates. Federal 25D credit is $0 for homeowner-owned systems from 2026.
- ✓Oregon Solar + Storage Rebate ($0.30–$0.60/W, up to $2,400 for residential)
- ✓Low-income additional rebates
- ✓Property tax exemption

State-specific decision guide
What to verify before signing a Oregon solar quote
In Oregon, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering. Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 4–8 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
