Installers, contractors and solar service companies whose service area covers Washington.
Washington runs on hydropower, but solar is having its growth spurt. The state has passed 600 megawatts of installed solar — nearly half of it arriving in a single record year — its largest farm, the 194-megawatt Lund Hill project in Klickitat County, now supplies Puget Sound Energy, and a 160-megawatt solar-plus-storage project in south-central Washington won state approval in late 2025. East of the Cascades, the Columbia Basin gets desert-grade sunshine; even the Puget Sound lowlands produce more than most people expect.
Net metering is guaranteed by state law at every utility — investor-owned, municipal, and cooperative alike — for systems up to 100 kW. Excess power is credited at the full retail rate on your next bill, and credits roll month to month, so long summer days bank against dark winter ones; whatever credit remains on March 31 each year is surrendered to the utility, which is why Washington systems are sized to annual usage rather than maxed out. Utilities can't tack on extra fees or insurance demands without state approval. One honest caveat: Washington's hydro-cheap electricity stretches payback longer than in most states — the payoff is locking in a share of your power at today's rates for decades.
Check the Washington rebates and incentives for your utility — several PUDs and city utilities add their own solar loans or community solar offers — compare the installers below from Seattle and Spokane to Bellingham and the Tri-Cities, and browse our solar energy resources for guides to cloudy-climate design, battery storage, and community solar.
