Word of the Founder
In 2009, I wanted to create BASE in order to make solar energy accessible to everyone. 10 years later, we have equiped a dozen of facilities with our Thermovoltaic panels Cogen’Air, a total of more than 5000 modules and thousands of autonomous photovolaic solutions across France. As a result, we have actively contributed to our clients energy transition by helping them becoming autonomous.
My biggest pride, beyond our clients’ satisfaction, was to be able to gather a team passionate and convinced of the necessary ecological transition.
