Best Solar Systems in Seattle, WA

Solar installation on the wet side works better than the weather jokes suggest — long summer days offset gray winters, net metering banks the difference, and federal credits apply. It's licensed electrical work with structural review.

$15,000–$35,000
Typical cost, before incentives

Call sooner, not later, if:
  • South- or west-facing roof with limited shade
  • Pairing with an EV or heat pump (self-consumption improves the math)
  • Roof replacement planning — do solar right after, not right before

Solar Systems: Common Questions

Does solar make sense in Western Washington?

The economics are honest-but-slower than Arizona: production is roughly 60–70% of sunbelt output, offset by net metering and incentives. Payback typically runs 10–14 years; on a shaded lot it may never pencil. A reputable installer will model your actual roof, not sell you averages.

What about winter production?

December produces a fraction of July — net metering is what makes it work, banking summer surplus against winter draw. Size the system against annual usage, not monthly.

How do I check a company's license?

Ask for their Washington L&I contractor number and verify it at secure.lni.wa.gov/verify — active license, bond, and insurance. Listings above with a green badge are ones we've already matched to an active license in state records.
