The Northwest’s Leader in Solar Solutions

CapStone Solar is a subsidiary of CapStone Solutions, Inc. Our roots began in telecommunications and building cell towers in remote locations all over the Northwestern United States. Many of these sites needed energy solutions, which led us into building large, utility-scale solar power facilities.  For example, the average utility-scale solar array that we construct is around 2.5MW, which is the equivalent of about 250 residential projects. We have multiple projects of this size under contract at any given time, giving us amazing economies of scale, and we pass those savings along to you with the best pricing on solar, period!

“We buy and install more solar panels than all of the other residential installers in Washington and Oregon combined, enabling us to pass along massive savings to our residential customers.”

CapStone Solar is also an innovative leader in the solar marketplace utilizing the most advanced technology in the industry. Our commitment to customer satisfaction is integral to every aspect of your journey in becoming your own clean, renewable power producer!
