Meet the Southwest Energy Systems Team!

About Us -Southwest Energy Systems

Southwest Energy Systems, LLC, was founded in 2006 when a group of experienced professionals came together with the goal of providing third-party electrical testing and engineering studies that would meet their clients’ needs for high quality and personalized service. We realized that a more client-focused company that was not beholden to any manufacturer would be in the best position to meet this goal.

Our clients proved us right. They wanted to work with people who had already established reputations for quality services and who would have the clients best interest in mind.

Our main office is in the Southwest, but we work with clients all over the United States. Wherever you’re located, we can bring you the same kind of personalized service that our clients in Arizona enjoy.
