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  Amazing service. I had ordered the monitoring device that needed upgrading. Herve was quick to respond and accommodate what it was that I needed. Sent it out with no fuss. It was a pleasure to see responsiveness and good communication in a company as so many lack this skill.

    review rating 5  Ipsun Power has been a great company to work with. They answered all of my questions regarding purchasing a solar system, guiding me through the whole process. The install crew that came to my house was very professional, courteous, and definitely knew what they were doing. Even after the project was complete, they submitted all the paperwork needed for me to receive the Fairfax County tax exemption! Also, Ipsun has a great website where all of my documents, pictures, project schedule, receipts, etc are all in one place, which is a great resource. Plus you get access to a phone app where you can monitor your solar panel performance in real time and trend it over the long term. Overall, I have no regrets with choosing Ipsun Power!
