Solar Companies in Washington

Washington State presents an interesting solar paradox - while the western half is famously cloudy, the eastern side of the Cascades receives strong sunshine. The Evergreen State averages about 3.4 peak sun hours daily statewide but has supportive policies that make solar viable even in the Puget Sound region.

Washington mandates full retail net metering for all utilities and exempts solar equipment from state sales tax. Puget Sound Energy, the state's largest investor-owned utility, participates in net metering, and many municipal utilities and cooperatives offer additional incentive programs. Washington's Clean Energy Transformation Act requires 100% clean electricity by 2045.

Seattle, Spokane, and Tacoma are the primary residential solar markets. With low electricity rates and modest sunshine in the west, payback periods tend to be 11-15 years, though eastern Washington homeowners with higher solar irradiance see better returns.
