Here's the Washington solar truth: Low electricity rates (thanks to hydroelectric power) make the financial case challenging, but state sales tax exemptions and excellent net metering help. I've analyzed PSE and Seattle City Light policies - the economics work for the right households.
If you're motivated by energy independence rather than just cost savings, Washington offers solid long-term value. The real benefit is protection against future rate increases and environmental impact reduction.

Washington ended its production incentive program in 2020. Current incentives focus on reducing upfront costs rather than performance payments.
Puget Sound Energy serves most of the Seattle metropolitan area. Their net metering program is straightforward and homeowner-friendly, which partially compensates for Washington's low electricity rates.
Bottom line: Washington utilities generally maintain favorable net metering. The challenge is the low baseline electricity rates, not unfriendly policies.
With lower electricity rates, system sizing and financing become more critical in Washington.
