We work every day to invent the energy technologies of the future, co-directed by Jérôme and Laetitia.

The capacity to provide solutions that produce both electricity and hot water to render our buildings energy-positive, all while being aware that rooftop space is not infinite – this is what drives us and defines our mission at DualSun.

The early days of DualSun

DualSun is the product of two very different personalities coming together, driven by the same obsession for innovation and access to a clean energy world. Jérôme Mouterde and Laetitia Brottier first met in a scientific prep school.

Their paths crossed again two years later while classmates at Centrale Paris, one of the top engineering schools in France.
Centrale provided Laetitia and Jérôme a springboard to endeavor on diverse entrepreneurial projects, both individual and together, and to affirm their aspiration to choose professional paths with significant societal impact.

DualSun started in the offices of Centrale Paris in 2008.
After signing a partnership with a CNRS laboratory specialized in energy in Marseille, the duo moved to Marseille in 2009, and from there, the team grew.

– The company was officially created in 2010 and the first DualSun panel was installed in August 2011.
