Washington Solar FAQ
+How much does residential solar cost in Washington?
A typical 8–10 kW system runs $20,000–$35,000 before incentives. The federal ITC currently covers 30%, and Washington may offer additional state rebates.
+Do I need a battery with solar in Washington?
Optional — but a battery (Tesla Powerwall, Enphase) provides backup during Washington outages and improves time-of-use savings under the local utility's rate plan.

On-site work runs 1–3 days. Permitting and PTO (permission to operate) in Washington can add 4–10 weeks depending on the utility.
