Oregon combines a solid statutory foundation with a rebate that moves often
The property tax exemption is automatic, but its end date applies to systems already installed
Oregon exempts the value a solar system adds to your home from property tax under ORS 307.175. Per the legislature's enrolled HB 2080, which set the current text, the exemption covers an alternative energy system that is a net metering facility or is primarily designed to offset onsite electricity use, and it equals whatever the system adds to the property's real market value, so your assessment doesn't climb because you installed panels. The statute contains no application requirement for homeowners, which is why guides describe this benefit as automatic. The catch is the end date: the statute says the exemption may not be allowed for property tax years beginning after July 1, 2029. The tax year that begins on July 1, 2029 is still covered, and the cutoff depends on the tax year rather than on when you installed. Some industry guides say systems installed before the deadline keep the exemption for life, but the statute doesn't say that, so unless the legislature extends the date, plan on the added value becoming taxable starting with the 2030-31 tax year. The property tax exemption savings calculator can show what that is worth to you over a longer horizon.
Energy Trust of Oregon pays a flat amount per home, and its own page settles most of the confusion
Guides published in 2026 cite very different Energy Trust figures: a flat $2,500, a per-watt rate of $0.90 capped at $5,500, tiered per-kilowatt rates, and others. Most of those numbers describe schedules that have since changed. According to Energy Trust's own Solar for Your Home page, updated in early October 2026, the standard incentive is a flat amount per home rather than a per-watt rate: $3,500 for Portland General Electric customers and $2,500 for Pacific Power customers, for systems of at least 2 kW DC. Batteries earn a separate incentive of $400 per kWh up to $5,000 for PGE customers and $240 per kWh up to $3,000 for Pacific Power customers, and the battery must connect to a qualifying solar system. The incentive is paid to your approved Trade Ally contractor and deducted from your invoice rather than mailed to you. The same page says offers depend on funding availability and may change at any time, and the numbers have moved in both directions: some guides report that PGE's solar amount rose in August 2026, while Pacific Power's battery figure on the official page is now lower than what older guides still show. Treat the amounts above as a snapshot, and get a current written quote from your contractor before you build a budget around them.
A separate state rebate exists, but its funding runs out almost immediately
The Oregon Department of Energy runs its own Oregon Solar + Storage Rebate Program, which offers up to $5,000 for solar and up to $2,500 for storage, separate from Energy Trust. Funding is the problem. ODOE announced $1.1 million in re-purposed funding for 2026 and reopened the program on June 15, and it reported the next day that the funds were fully reserved. As of ODOE's most recent update the program was not accepting new applications, so don't count on it in your budget, but check the Department of Energy's site for any future reopening, since a rebate of this size is worth knowing about if funding returns.
Net metering credits exports at full retail, then donates any leftover credit at the annual true-up
Oregon's net metering rules, set out in the Public Utility Commission's OAR 860-039-0055, credit each month's excess generation at your full retail rate for every billing component charged per kilowatt-hour, and unused credit carries forward from month to month. Because credits apply to the per-kilowatt-hour components of your bill, fixed charges such as a minimum monthly charge still apply. The annual cycle ends with the March billing month unless your utility agrees to a different date, and per the Commission, any credit still left after the 12-month period is transferred to customers enrolled in the utility's low-income assistance programs rather than paid to you. Residential systems up to 25 kW qualify. These billing details come from the rules for investor-owned utilities such as PGE and Pacific Power; municipal utilities, cooperatives, and people's utility districts must also offer net metering but set some terms themselves, so confirm yours. The practical takeaway is to size your system close to your own annual consumption, since surplus credit never turns into cash for you.
Only PGE and Pacific Power customers can use Energy Trust, and income-qualified households get a larger incentive
Energy Trust is funded through a charge on PGE and Pacific Power customer bills, so its incentives are limited to customers of those two utilities. If a people's utility district, a municipal utility such as Eugene Water & Electric Board, or a rural cooperative serves you, you generally won't qualify for Energy Trust funds, though some of those utilities may run their own programs, so ask yours directly. The property tax exemption and the statewide net metering requirement apply no matter who your utility is.
Households that qualify on income can use Energy Trust's Solar Within Reach track, which pays more. Per Energy Trust's Solar Within Reach page, updated in September 2026, PGE customers receive $1.25 per watt up to $7,500 and Pacific Power customers receive $0.75 per watt up to $4,750, with batteries at $500 per kWh up to $6,250 for PGE and $360 per kWh up to $4,500 for Pacific Power. Eligibility depends on household size and county income limits that the page lists, and the same funding caveat applies. If you may qualify, the community solar for low-income households tool is worth checking alongside it.
