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.

    As a business owner and consumer, it is so refreshing to work with another company who puts consumers and their needs first. Semper Solaris has been phenomenal to work with and considering I have worked with 3 other solar companies before, that’s saying a lot. My main point of contact, Angie, has paid close attention to all my needs and seriously gone above on beyond to help me and my family. Good customer service is soooo hard to find nowadays and that’s the only reason I’m taking time out of my day to let everyone know that Semper Solaris is more than great and if you have the opportunity to work with Angie, you won’t regret it. 5 stars and 2 thumbs up doesn’t even do them justice. Thanks guys for everything.

    I recently worked with Semper Solaris for my new roof, solar batteries, solar panel installation and an EV charger. The energy consultant who I worked with, Erica Powell, was the best part of my experience. She was professional, had expert knowledge of the products and services, and provided clear communication throughout the whole process. I appreciated her follow-up and aftercare, and I couldn't be happier with the service I received. I highly recommend Semper Solaris and Erica to anyone who is considering installing solar panels. 💯

    We have had our solar panels on our house since 2014. Semper Solaris has been great every time we have had questions. Today, Angie C helped us through the process of reconnecting our solar system to a new Wi-Fi. We got through it in about 10 minutes. Angie was great! We have referred friends and they have also been very happy with this company.

    The HVAC crew, David M and Jacob V are servicing our system and they are wonderful!!! David is teaching us how to take care of the system and his patience is amazing. He is so knowledgeable and efficient! Jacob is working so hard to clean every unit. This is especially important as we live on a ranch with dust and dirt so maintenance is mandatory. Thank you Semper Solaris for sending us such a great crew! And thanks to Cherice for organizing this so promptly. We love Semper Solaris!
