Diversified Energy

Diversified Energy has operated in the Greater New Orleans market for 27 years, building a business model that treats solar as one component of a broader home energy strategy. Founded in 1999 by Jeff Haag, the company is headquartered at 771 South Prieur Street in New Orleans and has grown into the Gulf South's leading provider of integrated residential and commercial energy solutions. Their approach starts with building performance diagnostic testing and works outward to HVAC optimization, insulation, and ultimately solar generation, a sequence that tends to produce better long-term results than installing panels on an inefficient building.

What distinguishes Diversified Energy from solar-only competitors is their BPI Gold Star Contractor certification. The company employs more Building Performance Institute-certified technicians than any other firm in Louisiana and is the only local company to have been recognized by both the U.S. Department of Energy and the EPA for improving energy efficiency and comfort. That pedigree in building science means their solar recommendations are grounded in a thorough understanding of how a home actually uses energy, rather than simply sizing a system to offset a utility bill.

The company has expanded its solar reach through partnerships with regional and national solar energy companies, non-profit organizations, electric utility rebate programs, and top home builders. These collaborations allow Diversified Energy to deliver customized energy efficiency solutions while maintaining their core expertise in building performance. Their service area extends across Greater New Orleans, Greater Baton Rouge, Lafayette, Houma-Thibodaux, and the Mississippi Gulf Coast, giving them broad geographic coverage in a state where solar market conditions vary significantly by parish.

Customer response has been strong. A 4.9-star Google rating across 365 verified reviews reflects the company's ability to explain complex energy concepts in accessible terms and deliver measurable results. Homeowners frequently report reduced energy bills and improved indoor comfort following Diversified Energy's whole-home assessments, an outcome that reinforces the value of their diagnostic-first approach.

With a composite score of 72.55 out of 100, Diversified Energy earns the third-ranked position among solar installers in Louisiana for 2026.
