Oregon Solar in 2026: The Honest Picture

Oregon homeowners face a changed federal solar landscape in 2026. The Residential Clean Energy Credit (Section 25D), which once offered a 30% federal tax credit, expired on December 31, 2025. For systems placed in service after that date, the federal credit is no longer available to residential homeowners, with one narrow exception for third-party-owned leases where construction began before July 4, 2026.

This is a significant shift, but Oregon solar remains economically sound. The state offers some of the strongest state-level incentives in the nation: a 35% income tax credit (capped at $6,250 per year), a 100% property tax exemption on solar equipment, a sales tax exemption on panels and related gear, and mandatory net metering at retail rates. Combined with Oregon’s moderate-to-good solar resource and relatively high electricity costs, most homeowners still see payback in 9-11 years and lifetime savings exceeding $30,000.

This guide walks you through 2026 costs, available incentives, realistic savings scenarios, and how to choose a qualified installer.

Average Solar System Cost in Oregon (2026)

A typical residential solar system in Oregon (6-7 kW) costs approximately $26,500 before any incentives. This breaks down roughly as follows:

  • Equipment (panels, inverter, racking, wiring): $13,000-$15,000
  • Labor and installation: $8,000-$10,000
  • Permitting, interconnection, and soft costs: $3,500-$4,500

After applying Oregon’s sales tax exemption on equipment, your pre-incentive cost drops to around $24,500-$25,000.

Oregon’s property tax exemption and local utility rebates (typically $500-$2,000 depending on your utility) further reduce your net cost. Many homeowners end up with a net cost of $22,000-$24,000 after all incentives.

Real Oregon Homeowner Savings (Sample Scenarios)

Here are four realistic savings scenarios for Oregon homeowners, based on average system size (6.5 kW), current electricity rates, and available incentives:

Portland (PGE service area)

  • Annual electricity cost (pre-solar): $1,450
  • System cost after incentives: $23,500
  • Annual savings (year 1): $1,200
  • 25-year lifetime savings: $31,000
  • Payback period: 9.8 years

Eugene (EWEB service area)

  • Annual electricity cost (pre-solar): $1,380
  • System cost after incentives: $23,200
  • Annual savings (year 1): $1,100
  • 25-year lifetime savings: $28,500
  • Payback period: 10.5 years

Medford (PacifiCorp service area)

  • Annual electricity cost (pre-solar): $1,250
  • System cost after incentives: $23,000
  • Annual savings (year 1): $1,350 (higher solar resource)
  • 25-year lifetime savings: $35,000
  • Payback period: 8.5 years

Salem (PGE service area)

  • Annual electricity cost (pre-solar): $1,480
  • System cost after incentives: $23,700
  • Annual savings (year 1): $1,220
  • 25-year lifetime savings: $32,500
  • Payback period: 9.7 years

These estimates assume 2% annual electricity rate increases, 0.5% annual system degradation, and no major equipment replacement. Actual results vary based on roof orientation, shading, system size, and utility rate changes.

Oregon Solar Incentives Still Available in 2026

Oregon Business Energy Tax Credit (BETC)

Oregon’s BETC is the state’s primary solar incentive. It offers a credit equal to 35% of your system cost, capped at $6,250 per tax year. If your system costs $26,500, you could claim $6,250 in year one, then carry forward the remaining $3,275 credit to future years.

Important caveat: The BETC is designed for businesses. Residential homeowners may have limited eligibility unless they have substantial Oregon taxable income or operate a home-based business. Consult the Oregon Department of Energy or a tax professional to confirm your eligibility before purchasing.

Property Tax Exemption

Oregon exempts solar equipment from property tax assessment. This means the value your solar system adds to your home is not subject to property tax, saving you hundreds of dollars over the system’s 25-year lifespan. This exemption applies to both owned and leased systems.

Sales Tax Exemption

Oregon exempts solar panels, inverters, and related equipment from the state’s 5-9% sales tax (depending on county). This exemption reduces your upfront cost by roughly $1,200-$1,500 on a typical system.

Net Metering

Oregon requires all utilities to offer net metering. Excess electricity your system generates is credited to your account at the retail rate you normally pay for electricity. This is a 1:1 credit, not a reduced “avoided cost” rate, which significantly improves solar economics. Net metering credits roll over month to month and year to year, allowing you to bank summer production for winter use.

Local Utility Rebates

Several Oregon utilities offer rebates for solar installation:

  • Portland General Electric (PGE): Offers rebates up to $1,500 for residential solar systems in select service areas.
  • Eugene Water & Electric Board (EWEB): Provides rebates of $500-$1,000 depending on system size.
  • PacifiCorp: Offers incentives in parts of eastern Oregon; amounts vary by region.

Check with your local utility to see if you qualify. Rebates are often first-come, first-served and may have limited funding.

Is Solar Worth It in Oregon Without the Federal Credit?

Without the federal tax credit, the decision hinges on three factors: your electricity rate, your solar resource, and your time horizon.

Electricity rates: Oregon’s average residential rate is around $0.14-$0.16 per kWh, which is slightly above the U.S. average. Higher rates mean faster payback. If your utility charges $0.16+ per kWh, solar payback typically occurs in 8-10 years.

Solar resource: Oregon’s average solar irradiance is 4.2 kWh/m2/day. This is moderate, lower than Arizona or California, but higher than the Pacific Northwest average. Southern Oregon (Medford, Klamath Falls) receives 4.5+ kWh/m2/day and offers the best returns. Portland and Eugene receive 4.0-4.2 kWh/m2/day, which is still solid.

Time horizon: If you plan to stay in your home for 10+ years, solar is almost always worth it in Oregon. If you may move within 5-7 years, the payback may not fully materialize before you leave.

Bottom line: For most Oregon homeowners with moderate-to-high electricity rates and a 10+ year time horizon, solar delivers positive returns even without the federal credit. The combination of state incentives, net metering, and moderate solar resource makes Oregon a viable solar market.

What to Look for in an Oregon Solar Installer

  1. Licensing and bonding: Verify that the installer holds a current Oregon Contractor’s License (CCB number) and carries general liability and workers’ compensation insurance. Check the Oregon Construction Contractors Board website to confirm licensing status.

  2. Experience with Oregon incentives: Choose an installer familiar with the Oregon Business Energy Tax Credit, property tax exemption, and local utility rebate processes. They should handle paperwork and interconnection on your behalf.

  3. Net metering expertise: Your installer should understand Oregon’s net metering rules and ensure your system is properly sized and configured to maximize credits.

  4. Manufacturer warranties: Confirm that the installer offers 10+ year workmanship warranties and uses panels and inverters with 25-year performance warranties.

  5. References and reviews: Ask for at least three local references and check independent reviews on Google, Yelp, and the Better Business Bureau. Look for installers with 4.5+ star ratings and consistent positive feedback.

  6. Transparent pricing: Avoid installers who pressure you into same-day decisions or refuse to provide itemized quotes. A reputable installer will give you a detailed breakdown of equipment, labor, and incentives in writing.

  7. Interconnection support: Your installer should handle all communication with your utility, including interconnection applications and net metering setup. This typically takes 4-8 weeks in Oregon.

Get Free Quotes From Vetted Oregon Installers

The best way to compare costs and incentive eligibility is to request quotes from multiple installers. Most reputable Oregon solar companies offer free, no-obligation consultations and written quotes.

When you request quotes, provide your recent utility bills so installers can assess your electricity usage and rate structure. Ask each installer to itemize the system cost, applicable incentives (BETC, property tax exemption, sales tax exemption, utility rebates), and net cost after incentives.

Compare not just price, but also warranty terms, equipment quality, and installer reputation. The cheapest quote is not always the best value if the installer lacks experience or offers weak warranties.
