Home solar in Oregon runs about $2.50 to $2.75 per watt, so a 7 kW system costs roughly $17,500 to $19,250 before incentives (confirm with local quotes). At Oregon’s 15.78 cents per kWh rate, simple payback is about 14 to 16 years, or nearer 11 to 13 years after the Energy Trust of Oregon rebate. The federal 25D homeowner credit ended December 31, 2025. For Oregon’s full incentive and net-metering picture, see our Oregon solar guide, and for PGE’s specific terms, the Portland General Electric net metering guide.
Oregon homeowners pay about 15.78 cents per kWh for electricity (EIA retail sales, residential Oregon, as of April 2026), a rate close to the national average. That moderate rate, paired with the Pacific Northwest’s cloudier skies, means each panel here makes and saves a bit less than it would in a sunny, high-rate state, which stretches the payback. The upside that sets Oregon apart is its incentives: the Energy Trust of Oregon still pays an upfront rebate that pulls the payback back down. This page walks the cost per watt, the payback math, and how those rebates change the picture. For how export credits work, see our guide to how net metering credits your solar exports.
A 7 kW rooftop system in Portland (ZIP 97201) produces about 7,827 kWh per year (NREL PVWatts v8), which is a modest yield reflecting the region’s roughly 12.8% capacity factor under cloudier Northwest skies. At Oregon’s 15.78 cents per kWh residential rate that production is worth about $1,235 a year (EIA, April 2026). Because Oregon credits exports near the retail rate, most of that value holds whether you use the power live or send it to the grid.
How much does solar cost in Oregon?
Price is quoted in dollars per watt of system size. Oregon installs run a little below the national average: 2026 cost surveys put the state around $2.50 to $2.75 per watt before any incentives, with the Portland metro at the low end near $2.48 per watt (EnergySage local cost data, Oregon). Treat the table as a planning range and get itemized local quotes to confirm your own dollars per watt. Your price moves with system size, roof complexity, panel and inverter choice, and the installer.
| System size | Fits a home that uses | Estimated installed cost ($2.50 to $2.75/W) |
|---|---|---|
| 5 kW | Smaller bill, roughly $90 to $140/mo | About $12,500 to $13,750 |
| 7 kW | Average bill, roughly $140 to $210/mo | About $17,500 to $19,250 |
| 10 kW | Larger home or an EV, $210+/mo | About $25,000 to $27,500 |
Cost ranges are 2026 Oregon market estimates for planning, not a guaranteed price. Oregon has no statewide sales tax, so there is no sales tax to add on equipment. The Energy Trust rebate below comes off these figures. Confirm your quote before you decide.
What is the solar payback in Oregon?
Simple payback on a typical Oregon system runs about 14 to 16 years before incentives, and closer to 11 to 14 years after the Energy Trust of Oregon rebate.
Payback is cost divided by what you stop paying the utility. Oregon’s retail rate is moderate and its sunlight is limited, so the yearly bill savings are modest, which is what stretches payback into the mid-teens before help. What shortens it is the upfront rebate: the Energy Trust of Oregon pays a flat incentive that comes straight off the sticker. The table pairs the cost above with a production-based offset, scaled from the verified Portland PVWatts figure by system size and priced at 15.78 cents per kWh, then shows payback before and after the rebate.
| System size | Estimated annual production | Yearly bill offset | Payback before incentives | Payback after Energy Trust rebate |
|---|---|---|---|---|
| 5 kW | About 5,590 kWh | About $880 | About 14 to 16 years | About 10 to 12 years |
| 7 kW | About 7,827 kWh | About $1,235 | About 14 to 16 years | About 11 to 13 years |
| 10 kW | About 11,180 kWh | About $1,765 | About 14 to 16 years | About 12 to 14 years |
Estimates, not a guarantee. Production is scaled from NREL PVWatts v8 for Portland (ZIP 97201) and priced at the current EIA rate. The after-rebate column subtracts an Energy Trust of Oregon rebate of about $3,500 for PGE customers (Pacific Power customers get about $2,500, which lands payback near the longer end); the rebate is subject to funding and eligibility. Rates, production, and prices vary, so verify your own numbers.
How Oregon incentives change the payback
Oregon’s incentive stack is leaner than it was, but it is not empty, and one active rebate does real work on the payback. Here is what each program pays in 2026 and the catch worth knowing.
| Program | 2026 value and status | Source |
|---|---|---|
| Energy Trust of Oregon rebate | Flat upfront rebate: about $3,500 per home for PGE customers, $2,500 for Pacific Power, applied through an approved trade ally. Active, subject to funding. | Energy Trust of Oregon |
| Oregon Solar + Storage Rebate (ODOE) | State rebate up to $5,000 for solar (higher per-watt for income-qualified homes), but funding is limited and the program was fully reserved and closed to new applications as of mid-2026. Verify current status before counting on it. | Oregon Dept. of Energy |
| Net metering | Retail-rate net metering for PGE and Pacific Power residential customers, so exported power is credited near the retail rate. Confirm your utility’s current tariff. | DSIRE, Oregon net metering |
| Federal residential (Section 25D) | The 30% federal homeowner credit ended for expenditures made after December 31, 2025, so a 2026 Oregon buyer cannot claim it. | IRS |
The Energy Trust rebate is the lever that still moves the number. For a PGE customer, that flat rebate of about $3,500 comes straight off the installed cost, which is why the after-rebate payback column above drops two to three years versus the sticker price (Energy Trust of Oregon). Amounts are set by your utility and are subject to funding, so confirm the current offer with an Energy Trust trade ally before you sign. The state’s Oregon Solar + Storage Rebate can stack more on top when it is open, but it was fully reserved and closed to new applications as of mid-2026, so do not build your budget around it until you confirm it has reopened (Oregon Department of Energy).

What moves your payback in 2026
Four things decide where you land in that window:
- The Energy Trust rebate. This is the biggest single lever left in Oregon. A flat rebate of about $3,500 for PGE customers or $2,500 for Pacific Power customers comes off the top when you install through an approved trade ally, and it is what pulls the payback down from the mid-teens (Energy Trust of Oregon).
- Northwest sunlight. Portland’s roughly 12.8% capacity factor means a system here makes less per kW than the same system in a sunny state, so the yearly bill savings are modest. Sizing to your actual usage, and a south-facing, unshaded roof, matter more here than in high-sun states (NREL PVWatts v8).
- Retail-rate net metering. Oregon credits exported power near the retail rate for PGE and Pacific Power residential customers, so unlike states that pay a low export rate, you keep most of the value even for power you send back to the grid. Confirm your utility’s current tariff (DSIRE). For the mechanics, see how net metering credits your solar exports.
- No federal credit in 2026. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so an Oregon homeowner buying with cash or a loan in 2026 cannot claim it (IRS). See what the federal solar tax credit change means in 2026.
How you pay changes the cost you carry
The sticker price is one thing; how you finance it decides your out-of-pocket and your payback.
| How you pay | Up-front cost | Best when |
|---|---|---|
| Cash | Full system price, minus the Energy Trust rebate | You want the shortest payback and the most lifetime savings |
| Solar loan | Little or none, financed over time | You want to own the system with low money down |
| Lease or PPA | $0-up-front where you qualify | You want no out-of-pocket cost and a lower or fixed power price without owning |
A lease or PPA has no up-front cost, but the company owns the panels, terms typically run 20 to 25 years and may include an annual escalator, and total payments can exceed a cash purchase. On a lease or PPA the Energy Trust rebate and any state rebate go to the company that owns the system, not to you. No 2026 Oregon homeowner gets the federal residential credit, since that credit ended after December 31, 2025. For a full payback breakdown, see the financial case for whether solar panels are worth it.
Frequently asked questions
How much do solar panels cost in Oregon in 2026?
Installed home solar in Oregon runs about $2.50 to $2.75 per watt before incentives, with the Portland metro near the low end. That puts a 5 kW system around $12,500 to $13,750, a 7 kW system about $17,500 to $19,250, and a 10 kW system about $25,000 to $27,500. Those are 2026 market estimates, so get itemized local quotes to confirm your own dollars per watt, then subtract the Energy Trust of Oregon rebate.
What is the payback on solar in Oregon?
Simple payback runs about 14 to 16 years before incentives and closer to 11 to 14 years after the Energy Trust of Oregon rebate. A 7 kW system in Portland produces about 7,827 kWh per year (NREL PVWatts v8), worth about $1,235 at Oregon’s 15.78 cents per kWh rate (EIA, April 2026). Payback is longer than in sunny, high-rate states because the Northwest gets less sun, but Oregon’s retail-rate net metering and upfront rebate help offset that.
Does the Energy Trust of Oregon still pay a solar rebate in 2026?
Yes. The Energy Trust of Oregon pays a flat upfront residential solar rebate, about $3,500 per home for Portland General Electric customers and $2,500 for Pacific Power customers, when you install through an approved trade ally (Energy Trust of Oregon). Amounts are subject to funding and can change, so confirm the current offer before you sign. This rebate is what pulls Oregon’s payback down from the mid-teens.
Is the Oregon Solar + Storage Rebate available right now?
Not always. The Oregon Department of Energy’s Solar + Storage Rebate Program pays up to $5,000 for solar, but it is funded in limited rounds and was fully reserved and closed to new applications as of mid-2026. It reopens when the state adds funding, so check the ODOE program page for current status before you count on it in your budget.
Does an Oregon homeowner qualify for the federal solar tax credit in 2026?
Not as a homeowner buying in 2026. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a cash or loan buyer cannot claim it. A separate commercial credit (Section 48E) can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner.
