Nexus Energy Systems

What Nexus Energy Systems does

Nexus Energy Systems is a residential solar, battery storage, and roofing installer headquartered in Garden Grove, California (also operating in Anaheim per firmographic data), serving homeowners in five U.S. states: California, New Mexico, North Carolina, and Virginia, with an additional Northern California office in San Jose. The company traces its roots to Rietkerk Construction, founded in 1978 by CEO Michael Rietkerk as a custom home builder, and formally entered the residential solar market in 2008. The company has completed 25,000+ solar installations and currently deploys 500,000+ Enphase microinverters across its fleet. Nexus is family-owned, has never raised outside funding, and owns its operating assets.

The product stack combines solar panel installation (Hanwha Q Cells panels, Enphase microinverters, Unirac racking), two battery storage lines (Tesla Powerwall and Enphase Encharge), and roofing services bundled through an Owens Corning partnership. System design is supported by the third-party Aurora Enterprise platform, which uses satellite imagery, Lidar 3D elevation mapping, and sun path simulations. A 25-year power production guarantee covering free maintenance and repairs is the central commercial commitment, alongside a 100% workmanship guarantee and a double-backed Owens Corning/Nexus lifetime roofing guarantee.

The business model is direct-to-consumer, with no dealer or reseller network: sales consultants perform in-home or virtual consultations and assessments, and all installation is performed by in-house crews. Pricing is not publicly disclosed but is framed around $0 out-of-pocket, cash-flow-positive from day one, with financing accessed through six partner lenders (Sunlight Financial, Goodleap, Palmetto/LightReach, Climate First, Dividend, Enfin) and stacked federal (30% Investment Tax Credit under the Inflation Reduction Act) and state tax credits. Customer acquisition relies on a $1,000 referral program, an interactive savings calculator, content marketing (news/blog authored by Chris Zettel), customer testimonials, and reputation signals (A+ BBB rating, Yelp and Google reviews). Revenue is generated primarily from one-time installation project revenue, with ongoing warranty services embedded in the 25-year guarantee.
