Why this site
Solar sales pitches are everywhere, and they rarely show their math. We built a free estimator for Washington and Oregon homeowners that shows every number and where it came from, so you can walk into a sales call already knowing the ballpark.
How we keep it honest
- Sun data comes from PVWatts runs. Prices come from the EIA and Berkeley Lab. We link every source.
- If something isn't published, we say so instead of guessing.
- We don't sell leads, and we don't take money from installers.
Independence
We're not affiliated with any utility, installer or government agency. Some links go to Amazon, and as an Amazon Associate we earn from qualifying purchases. That never changes the estimate.
