Green Stock Solar

Green Stock Solar is a Napa-based solar energy company founded in 2011 by David Peterson. The company specializes in both residential and commercial photovoltaic system design and installation throughout Napa County and surrounding areas. Distinct from many competitors, Green Stock Solar employs only an in-house team of installers personally trained by the founder—eschewing subcontractors to ensure quality workmanship.
Their approach emphasizes transparency: customers receive estimates via email without pressure from salespeople. The firm prioritizes customer education over high-pressure tactics, aiming to empower clients with knowledge for informed decision-making about going solar.
Green Stock Solar uses premium equipment such as LG or SolarWorld panels paired with Enphase microinverters for optimal performance and reliability. They also provide comprehensive post-installation support—including monitoring setup—and uniquely guarantee that if their installed systems do not meet promised energy output after one year, they will add more panels at no extra charge.
The company's mission centers on delivering superior value through quality installations at competitive prices while fostering long-term customer satisfaction that drives referrals within the community.
