This page walks through each program, what it actually pays, and a few claims that do not match the underlying statute.
Federal: Residential Clean Energy Credit (Section 25D)
The 30% federal Residential Clean Energy Credit expired for systems placed in service after December 31, 2025, under Public Law 119-21 (the One Big Beautiful Bill). The credit covered solar electric property, battery storage of 3 kWh or more, and associated labor and balance-of-system costs at qualifying U.S. residences. Re-roofing and structural roof work unrelated to mounting did not qualify even while the credit was active. IRS Residential Clean Energy Credit guidance and the IRS FAQ on P.L. 119-21 document the cutoff.
Section 48E (the commercial clean electricity credit) remains in effect for third-party-owned systems. In a lease or power purchase agreement, the leasing company owns the system and claims the 48E credit; the homeowner does not. Summit’s detailed explanation lives on the page on the 2026 federal credit.
State: Energy Trust of Oregon (ETO)
Oregon compensates residential solar systems through Energy Trust of Oregon (ETO) , administered by Energy Trust of Oregon. The program structure varies by state, but the practical question for a Oregon City homeowner is the same: how much of the system price does the state program offset, and is the value delivered up front or over time?
A homeowner should ask any installer to break out the Energy Trust of Oregon (ETO) value as a line item on the proposal so the math is visible, not bundled into the headline net price. Current values and contract terms are documented on the Energy Trust of Oregon site linked above, and the Energy Trust of Oregon (ETO) value is one of the inputs that determines the post-incentive net on the Oregon City cost page.
Utility / state rebate: Energy Trust of Oregon residential solar rebate
Energy Trust of Oregon residential solar rebate delivers an additional up-front benefit to qualifying residential systems in Oregon: Flat $2,500 for PGE customers through an ETO Trade Ally installer. Income-qualified households eligible for up to $5,500 through Solar Within Reach at $0.90/W.. Eligibility rules and rebate amounts move with the utility's tariff cycle or the program year, so the figure on any installer's proposal should be verified against the current Energy Trust of Oregon Trade Ally network before treating it as a fixed input.
City and county: Clackamas County
DSIRE, the federally funded clearinghouse for state and local energy incentives, lists city-level solar incentives where they exist. For most Oregon municipalities, including Oregon City, the state and utility programs are the full incentive stack; there is no city-specific rebate or income-tax credit layered on top. Verify the current state of any local incentive at DSIRE’s Oregon page before signing.
State-specific compliance note
Oregon's residential property tax exemption for qualifying solar (ORS 307.175) SUNSETS July 1, 2029. Systems installed after that date will not qualify absent legislative extension. "Permanent exemption" copy is wrong for Oregon. Forest Grove and Canby are municipal utilities, not PGE, and ETO rebate eligibility does not transfer automatically to muni-utility customers.
Verifying these numbers
Every figure on this page traces to a primary source: IRS guidance for the federal credit, the Energy Trust of Oregon (ETO) public documents for the state-incentive value, Oregon Public Utility Commission tariff filings for Portland General Electric program terms, and DSIRE for any local additions. Summit’s methodology page lists the verification process and the dates each input was last checked.
