About Semper Solaris

  • Semper Solaris was founded in 2012 with a mission to help California homeowners escape the ever-rising costs of traditional energy companies. Co-founders Kelly Shawhan, a former United States Marine Corps Captain, and John Almond, a seasoned business leader with a decade of experience in construction, saw an opportunity to bring military values—honesty, integrity, and hard work—into the world of solar power. With their combined experience and passion, they set out to help homeowners declare their independence from energy companies by embracing the then-emerging technology of solar power. Starting in the competitive solar market of San Diego, Semper Solaris grew by standing out through exceptional customer service and high-quality installations. Their military discipline and attention to detail became the foundation of every project, earning them a reputation as a trusted, local, veteran-owned business with thousands of 5-star reviews. Several years after launching, Semper Solaris expanded its services to include battery storage, roofing, and HVAC, knowing they could apply the same values to these verticals. Today, the company continues to offer comprehensive home improvement services while maintaining its strong connection to the veteran community. Through the Semper Cares initiative, Semper Solaris gives back by providing energy solutions to deserving veterans and hiring veterans whenever possible. As Semper Solaris grows into new states and adds more services, the company remains dedicated to instilling its core values into every employee and project. With a commitment to quality, service, and community, Semper Solaris is proud to be a leader in solar and home improvement services, and they will continue to expand to better serve homeowners across the country.

    ★★★★★

    Josh went above and beyond to help us with our problem and was so quick to find solutions and resolve our issue with the enphase system. I have never seen such fast service before, he was quick in contacting the people who ran enphase and extremely quick in touching base and keeping us up to date with what's happening with our system.

    My husband and I sat down with Roland not knowing what to expect but hoping for the best and that's exactly what we got. He explained everything in detail and made sure we understood everything. He was very personable and very attentive and and was very interested in what we had to say answering all our questions. I've seen many commercials about semper Solaris and what they portray on the commercials is absolutely true I would highly recommend Roland he's the best.

    Danny was amazing (again) he had to come by to permanently install our new thermostat. We were the first call on his schedule and was on time, he made sure that everything was working properly before leaving! He answers all the questions we have and also explains details on how AC cooling system works in ways we understand. Danny is great and I highly recommend Semper Solaris!

    Had to get on with tech support as the system wasn't communicating and Angie C. was super helpful. She was very knowledgeable and took every step to educate me about solar energy production and system ownership. Grateful to have had the opportunity to work with her.
