CapStone Solar

CapStone Solar is a leading integrated solar contractor based in Lacey, Washington. As a subsidiary of CapStone Solutions, Inc., the company’s origins trace back to telecommunications infrastructure—specifically constructing cell towers in remote areas across the Northwestern United States. This experience led them into utility-scale solar projects to power those sites before expanding into commercial and residential markets.
Today, CapStone Solar offers comprehensive turnkey services for homes, businesses, and large commercial deployments throughout Washington State and beyond. Their process covers every stage from initial consultation (including detailed energy modeling), site assessment with drone technology, custom system design using specialized software, permitting with local authorities/utilities, professional installation by an experienced team (typically completed within 1–3 days for residential systems), through to ongoing support.
The company leverages economies of scale from its utility-scale operations to offer competitive pricing on high-quality equipment. They are recognized as one of Washington’s top-rated installers due to their customer-centric approach—emphasizing transparency at every step—and their ability to deliver tailored solutions that maximize efficiency and long-term value for clients seeking sustainable energy independence.
