Endurance Solar and Engineering was founded in Boulder, Colorado in 2009 by Brian Bruggeman, P.E., a professional engineer with extensive experience in solar PV, electrical engineering, and home efficiency. From the beginning, the company was built on a straightforward mission: making solar energy accessible to everyone through expertise, personalized service, and a commitment to the environment. As a solar installer in Boulder, Endurance Solar has grown to serve homeowners and businesses throughout the Front Range and across Colorado from two locations in Boulder and Fort Collins. The founding team, which includes co-founder Kelby Bethards, brought deep technical knowledge to the residential and commercial solar market at a time when Colorado homeowners were seeking trustworthy guidance through the complexities of going solar. Endurance Solar holds NABCEP certifications and maintains a staff that includes professional engineers and electrical engineers—credentials that matter when designing custom solar installations that must perform reliably for decades. The company specializes in both grid-tied and off-grid solar panel systems, along with battery backup solutions and energy monitoring. Endurance Solar became a SunPower Premier Dealer, offering some of the highest-efficiency solar panels available and backing their installations with a 10-year workmanship warranty. Their approach has always centered on treating each home as unique, taking time to understand energy usage patterns and financial goals before recommending a system size or technology. The company has completed projects for notable clients including the Denver Zoo, University of New Mexico, and donated solar arrays to Habitat for Humanity, reflecting their commitment to community impact. For Boulder homeowners and businesses throughout Colorado, Endurance Solar represents the kind of local solar expertise that combines engineering precision with an understanding of regional conditions, utility interconnection requirements with Xcel Energy, and the specific incentives available to Colorado residents. Whether designing a residential rooftop system in the Denver Metro area or a commercial installation in Colorado Springs, their in-house design and installation approach means one team handles the entire project from initial assessment through final commissioning and ongoing service.
