About West Coast Solar
West Coast Solar is a California solar installation company that has been in business since 2007 and has completed more than 4,200 installations, earning a 4.4-star customer rating. Reachable at (925) 516-3900, the company serves both homeowners and business owners with residential solar systems, commercial solar installations, and service and maintenance for existing systems. For homeowners, West Coast Solar provides custom-sized systems with optional battery backup and zero-down financing options. Commercial clients can access large-scale solar projects that may qualify for federal tax incentives. The company manages the full installation process, including system design, permit handling, structural engineering, HOA approvals, and utility paperwork. Customers who prefer a fully online purchase experience can build their system through the company's self-service tool — uploading a PG&E bill, selecting a system configuration, locking in pricing with a deposit, and signing contracts digitally, without going through a traditional sales process. West Coast Solar also offers transparent maintenance packages and warranty information for customers with existing systems who need ongoing support. The typical payback period cited is six to eight years, with financing options available at zero down.
