About Nexus Energy Systems
Nexus Energy Systems is a solar and roofing contractor based in Garden Grove, California, with a company history dating to 1978, when founder Michael Rietkerk launched as a licensed General-B contractor serving California homeowners. Over more than four decades, Nexus has completed over 20,000 solar installations and deployed more than 500,000 Enphase microinverters across its customer fleet. The company installs solar systems on composite shingle, metal tile, and ground-mount configurations, and pairs solar with energy storage through both Tesla Battery Storage and Enphase Encharge Battery Storage solutions. Roofing services are also available. Nexus backs its work with a 25-year warranty covering maintenance and repairs, a production guarantee that provides no-charge remediation if a system underperforms, and a 100% workmanship guarantee from site survey through final installation. The company holds an A+ rating from the Better Business Bureau. Nexus works with vetted equipment and financing partners to help California homeowners maximize long-term savings and offers a savings calculator on their website for prospective customers to estimate potential returns before committing.
