What Our Solar Customers Have to Say

  • We had been considering solar power for quite some time, and having Western Solar's representative explain their system to us, we knew this was exactly what we had been looking for. The communication before and during installation and the actual installation itself was amazing! Western Solar's install crew are truly professionals. We would definitely recommend Western Solar to anyone.
    Gary & Pam I.6 kW solar PV system, Ferndale
  • We had an outstanding job done by the team from Western Solar, from start to finish everyone involved exceeded our expectations. The quality of craftsmanship was superior. I’m sure that we will call on them again when we expand our solar system in the future.  
    Tim and Janet M.4.8 kW solar PV system, Snohomish
  • I am very happy to have finally realized a lifelong goal to be a ‘producer’ rather than just a consumer of electricity. I like my system for the way it makes me feel on a sunny day. And on not so sunny days also! We are the envy of our local environmental discussion group for following through on ‘going solar’.
    Fred S.4.32 kW solar PV system, Kirkland
  • Power outage this morning. My SkyBox is up and running flawlessly. Hot water, hot coffee, cold beer (for later), internet, oh, and all of the critical loads weren’t interrupted. I can hear the neighbors’ generator, but not my SkyBox.
    Bo M.Skybox, Woodinville
  • Working with Western Solar was exceptional from initial sales inquiry all the way through to project completion and system activation. They have provided us with a complete turn-key solution with superior customer service. Communication with all members of their team have been professional and timely with the attitude that the customer always comes first. I am very impressed with Western Solar and would highly recommend them to anyone considering a solar system.

  • Adding solar panels to our house is a financially sound investment opportunity that offer a better than average rate of return for the life of the panels, is environmentally correct, adds value to our house, and is a feel-good thing to do. What more can you want?
