Our Story

Hervé Billiet
Joe Marhamati

Herve and Joe met at the U.S. Department of Energy where they collaborated on technical analysis of financing for some of the world’s largest renewable energy projects. Together they assisted teams which financed over $30B in everything from electric vehicles to renewable energy generation.

Herve is an electro-mechanical engineer who designed the first Belgian solar car and began developing solar projects in Alabama in the 2000s. Joe is an environmental scientist and served as Energy Advisor to President Obama’s Chief Sustainability Officer. They believe that solar should be accessible to everyone and created Ipsun Power, Ipsum meaning yourself in Latin. Our goal is to inspire all Americans to generate their own power from clean and renewable sunshine.

    review rating 5  First and foremost, they are THE BEST! I have a large home (over 8,000 square feet). Their pricing and their professionalism are far better than the competition. The system installation has completely met my expectations and exceeded. Everything went thoroughly smoothly, without a hitch. There have been absolutely NO maintenance issues since installation. Honestly, I wouldn't waste my time with any other company. Cheers and Blessings, Trish ~
