Is solar worth it in Washington?

Solar makes the most sense where electricity is expensive and there's plenty of sun. In Washington, residential electricity runs about 11¢/kWh and a typical household spends around $1,320/year on power. A standard 8 kW system offsetting most of that usage would save roughly $1,290/year, paying for itself in about 13 years and then producing largely free electricity for the rest of its 25+ year life.

Your actual result depends on your roof, shading, exact usage, installer pricing, and any state or utility incentives on top of the 30% federal credit. Always get a couple of real quotes.
