Oregon has a solid solar setup for 2026. Our model puts typical payback in the ~8–10 year range on a competitive install bid; on the calculator's default high-end pricing the payback stretches further. The federal credit is gone and Oregon has no state income tax credit, but the rest of the stack does the work:

  1. 1:1 retail net metering on PGE and Pacific Power (the two major IOUs) for systems up to 25 kW.
  2. Energy Trust of Oregon $2,500 upfront rebate for PGE/Pacific customers — applied at install as a direct discount, NOT a tax credit.
  3. No statewide sales tax at all — Oregon is one of only five US states without a sales tax.
  4. Property tax exemption on added home value, automatic.
  5. Active Energy Trust battery rebate (~$400/kWh up to $5,000), similar to Minnesota's active rebate program.

One common misreading to clear up before reading further: some sources cite an "avoided cost ~4-5¢" rate as the Oregon export rate. That's wrong. Avoided cost applies only to the leftover annual surplus at the March reset, not your regular monthly exports — which are credited at full retail 1:1.

What changed

The federal Residential Clean Energy Credit (§25D) — the 30% homeowner credit — was repealed for systems installed after December 31, 2025. For 2026 Oregon buyers, the federal credit on a purchased system is $0. The same applies to home batteries purchased outright. The §48E commercial credit (30%) still exists, but only for leased or third-party-owned systems — the lessor claims it, not you. Full federal context here.

Net metering: 1:1 retail, with a March reset twist

Oregon's net metering rules (OAR 860-039) require PGE (largest, ~900,000 customers, modeled here) and Pacific Power to credit residential rooftop solar at full retail 1:1 for systems up to 25 kW.

How it works:

The March-reset rule is similar to Washington's March 31 reset and Montana's annual settle-up — surplus credit you don't use within the year has zero value to you. Don't oversize beyond your annual consumption.

The "avoided cost ~4-5¢" confusion. Some sources cite an avoided cost rate of around ~4-5¢/kWh as Oregon's export rate. They're misreading the rule. That avoided cost rate applies only to the leftover surplus before it gets donated at the March reset — it is not how your regular monthly exports are valued. Regular monthly exports get full retail. If a quote or article treats your exports as 4-5¢, that math is wrong.

EWEB (Eugene Water & Electric Board) is a municipal utility that does credit exports at a much lower rate (~$0.0399/kWh) — but EWEB customers aren't on the OAR 860-039 IOU rules. Some other PUDs (public utility districts) also use lower rates. This calculator models the PGE/Pacific 1:1 case; verify your specific utility if you're outside PGE or Pacific.

The driver: ~14¢/kWh retail (and rising fast)

Oregon residential retail averages ~14¢/kWh (EIA ~12.4¢, EnergySage ~17¢) — below the US average due to abundant Pacific Northwest hydropower. That's the value of every kWh of solar you self-consume or export under 1:1 net metering.

The catch: rates are rising fast. Oregon retail has gone up about 40% since 2020. PGE raised rates roughly 5% in 2026, Pacific Power roughly 3%. Higher future retail improves the lifetime value of any solar system installed today, but the headline payback number reflects today's rates.

This is the same dynamic that makes Washington solar payback long — cheap hydropower-derived electricity makes the per-kWh savings modest, even with 1:1 net metering. Oregon's stack does better than Washington's because Energy Trust adds a real upfront rebate and there's no sales tax to pay.

Energy Trust of Oregon — flat $2,500 upfront rebate (NOT a tax credit)

This is Oregon's main state-level solar incentive. Read the structure carefully because it differs from how most state incentives work.

Energy Trust of Oregon pays a flat $2,500 cash rebate for residential solar on PGE or Pacific Power. The structure:

In the calculator above, you'll see Energy Trust shown as a line item that reduces gross cost to your displayed net cost — the same mechanism we use for Maryland's MEA grant ($1,000 flat) and Wisconsin's Focus on Energy rebate ($600/kW capped at $2,400). Oregon's $2,500 flat is the largest of the three.

If you're outside PGE/Pacific — most often a customer of a PUD or EWEB — Energy Trust doesn't apply to you. You may instead qualify for an Oregon Department of Energy (ODOE) rebate up to $5,000, depending on your situation and the program year. We don't model the ODOE rebate because amounts vary; ask your installer whether you qualify.

No state income tax credit (RETC expired 2017)

Oregon does not currently offer a state income tax credit for residential solar. The previous Residential Energy Tax Credit (RETC) expired in 2017 and has not been replaced. If you see a quote or article citing an Oregon state solar income tax credit, the program is gone.

The Oregon state-level incentive picture is the Energy Trust rebate, net metering, and the tax exemptions below — not a tax credit. Don't budget for one.

Exemptions: no sales tax (statewide) and automatic property tax

No statewide sales tax. Oregon is one of only five US states without a sales tax (along with Alaska, Hawaii, Montana, Delaware, and New Hampshire). There is no sales tax to apply to your solar installation. This is structurally different from states like Washington or Minnesota where solar gets an exemption from sales tax — in Oregon, there's nothing to be exempted from.

The practical result is the same as a sales tax exemption: your installed quote should not include sales tax, and there's no separate calculator line for it.

Property tax exemption. Oregon automatically exempts the added home value from solar from property tax assessment. No application required — unlike Maine, where you have to apply with your town to claim the exemption.

Battery in Oregon — weak arbitrage, active rebate, real resilience

Under Oregon's 1:1 retail net metering, the retail-vs-export gap is effectively zero — same as Florida, Virginia, Maryland, and other 1:1 states. On pure energy arbitrage, a battery in Oregon doesn't pay off.

What changes the math is the Energy Trust battery rebate — about $400/kWh up to $5,000. On a 10 kWh battery that's up to $4,000 off — material reduction in net cost. This is similar to Minnesota's active battery rebate, and both states are unusual in 2026 for having functional battery storage incentives. Most US states have nothing on the battery side beyond the (repealed) federal credit.

We do not auto-apply the Energy Trust battery rebate in the calculator because amounts vary by program year and funding is limited. Ask your Energy Trust Trade Ally contractor about current battery rebate availability before committing.

Oregon also has real resilience drivers: ice-storm season outages and wildfire-related power shutoffs are both regular events in much of the state. The avoided cost per outage hour at ~14¢ retail is modest, but the operational case — keeping critical loads running during multi-day events — is solid.

There's no federal credit on the battery purchase in 2026 (§25D repealed).

The honest picture

Oregon solar in 2026:

Oregon's case for solar in 2026 is more durable than Washington's at similar retail rates — partly because Energy Trust adds real upfront dollars, partly because Oregon hasn't given utilities the kind of notice WA's PSE and Seattle City Light gave their customers about ending 1:1. OR is holding its 1:1 rule; WA is changing it. That's a real structural difference between the two PNW states for buyers in 2026.

The stack works because the pieces stack: $2,500 upfront from Energy Trust + no sales tax + 1:1 net metering + property tax exemption + (potential) battery rebate. None of those pieces is huge by itself, but together they bring payback into the high-single-digit range for buyers on competitive installs.

For context, Oregon also has a robust community solar program for residents who don't or can't install rooftop — but that's a separate program and not what this calculator models.
