We had a project to construct a lean-to adjacent to our barn and wanted to cover it in solar panels. The Solar Stone gave us a detailed estimate, power generation prediction and explained the entire Washington State incentive variations and application process which helped us become more informed.<br /><br />The entire construction process went smoothly despite some weather conditions mid-December and we were able to get the project signed off before the New Year. They were communicative throughout the project and it was a pleasure working with them.<br /><br />Solar projects should be installed by skilled professionals who know what they're doing when it comes to installing expensive equipment you're wanting to use for 25+ years. The Solar Stone are those professionals and I'd recommend them to anyone.
