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.

    Angie was amazing. She was professional, patient, kind, and extremely knowledgeable. I struggle with some of the jargon related to solar, and she was willing to break down all aspects into more digestible terms for me. She addressed every single one of my questions and I left our meeting, feeling confident in what the next steps were and what I needed to address. We got everything addressed that I needed in a timely fashion and with much less anxiety than I was expecting. I highly recommend her.

    My overall experience with Semper Solaris has been exceptional. Recently I had some questions regarding my systems performance and reached out for support. I spoke with Angie who was very helpful and extremely knowledgeable on how my system works. This is critical as I needed to have a better understanding of how my system functions overall.

    We moved into a new home with Semper Solaris installed solar and a Tesla Powerwall system. Josh D. immediately helped us get up and running with Semper Solaris. But we were having issues getting the Tesla system to function properly. Josh D. took the helm and pushed everything through the Tesla system. While we waited on Tesla, he frequently touched base to give us updates. Ultimately, his efforts got all of our glitches with Tesla resolved. Josh D. is definitely one of the most diligent customer service professionals I have dealt with and is a tremendous asset to Semper Solaris. Thanks!

    We contracted with Semper Solaris for a new roof. They were great to work with. They were responsive, flexible and knowledgeable. Timothy Aubert, the Field Supervisor was in touch everyday to let us know what was scheduled for that day. He was always available for questions. It was a relatively quick process. They were very respectful of our property and landscaping. We highly recommend them!
