Ways to lower your Portland price
- Claim the 30% federal credit and stack any state, utility or property-tax incentives.
- Size the system to your actual usage — oversizing rarely pays back where net metering is capped.
- Get at least three quotes; per-watt pricing varies 40% between installers in the same market.
- Cash or a credit-union loan usually beats dealer-financed solar loans with hidden fees.
- Replace an aging roof before installing, not after — removal and reinstall costs $3,000 to $6,000.
