What Complete Solar does
Complete Solar is a US-based residential solar energy company headquartered in San Mateo, California, founded in 2010 and operating with 101–250 employees. The company sells, finances, and installs solar energy systems for homeowners, with a product stack centered on premium monocrystalline solar panels paired with third-party battery storage hardware (Enphase IQ Battery 10C and 5P) and a 25-year manufacturer warranty that supports a quality/premium positioning relative to commodity installers.
The business operates a hybrid go-to-market: a direct-to-consumer front-end combining a website quote-request flow and a phone sales channel (877-299-4943) targeting individual homeowners, supplemented by a B2B builder and multifamily developer partnership program that integrates solar into new construction projects. Revenue is generated across three streams — hardware sales, professional installation services, and consumer solar financing arrangements — with quote-based per-project pricing rather than subscription contracts.
Complete Solar has raised approximately $34 million across five disclosed funding rounds from 2011 through February 2023, with the most recent $10 million rounds led by Foris Ventures (Feb 2023) and Kline Hill Partners (Dec 2022). Leadership is held by co-founder Will Anderson (CEO) and Dave Anderson (CMO/co-founder). Earlier rounds brought in mission-aligned capital from Ecosystem Integrity Fund, Libra Foundation, and Floodgate.
