The checklist

What to verify before you sign

  1. Step 1

    Verify the Oregon CCB license

    Every installer must hold an active Construction Contractors Board license. Search it to see the license status, bond, insurance and any complaints on record.

  2. Step 2

    Confirm Energy Trust trade ally status

    PGE and Pacific Power customers can only get Energy Trust of Oregon solar incentives through an approved trade ally. Allies are held to installation standards and inspections.

  3. Step 3

    Ask who does the installation

    Some companies sell the contract and hire subcontractors to install it. Ask whether the crew is in-house, and who you call for service in year five.

  4. Step 4

    Compare warranties line by line

    Look for separate panel, inverter or battery, and workmanship warranties. A 10-year or longer workmanship warranty from a company with a long Oregon track record matters more than a long promise from a new one.

  5. Step 5

    Check the savings math

    A trustworthy proposal uses your actual 12-month usage, your utility's real rate, and modest rate escalation. Be wary of savings that assume rates rising 6% or more every year.

  6. Step 6

    Read reviews across platforms

    Compare Google, BBB and the CCB complaint history. Look at how the company responds to problems, not only at the star rating.

Red flags

Walk away if you hear these

  • Pressure to sign the same day, or a deal that expires tonight
  • Claims of a 30% federal tax credit on a purchased system installed in 2026
  • "Free solar" pitches that turn out to be a lease or PPA you didn't realize you were signing
  • No site visit or roof assessment before a final price
  • A salesperson who can't tell you who will actually install the system
