    Solar Installers of Washington SIW

    Solar Installers of Washington (SIW)

    Established October 2013, Solar Installers of Washington (SIW) is a professional trade association founded to serve the specific needs and interests of solar installation companies in Washington state. SIW also represents the interests of Washington-based solar installers in conversations with manufacturers, distributors, and allies that routinely interact with its members.

    The passing of the Solar Jobs Bill and the Washington state solar production incentive is a direct legislative result made only possible by the hard work and cooperation of SIW-members and passionate solar advocates in the community.
