To understand Joule, you have to understand what sets us apart. The Joule Difference is about delivering peace of mind on all fronts, from our team’s specialized experience to our attention to customer service. Many companies promise savings, but we promise that you will enjoy every step of the process. Joule is a B-Corporation that believes in a “triple bottom line” philosophy. With any major decision, we consider not just what will help us grow as a company, but about our impact on our community and the environment. One of the first B-Corps in Louisiana, we are the only solar company in the state with this designation.
