Our company

A pioneer company, expert and international

The source of many beautiful stories is always a meeting:  ECOSUN Expert is no exception to this rule. Indeed, the company emerged from the meeting of four entrepreneurs, each of them, entering from conviction in the world of renewable energies.

« We had ideas we put together and gave birth to our first achievements, designed for us. Furthermore, other actors came to see us and presented us with confidence their projects that we had to reproduce for them what we had put into practice and what meanwhile has proven its value. »

Thus, ECOSUN EXPERT has developed, whose area of ​​expertise does not cease to expand.

Although it is a French company, it does not know any borders, because its founders complementary paths, who are each  attached to different geographical areas from the historically point of view. Thus, we shine in the world, both in Europe and in North America or in Africa.

This international presence enables global identification of all issues, and of opportunities faced today by the renewables. Echoing these problems, the philosophy of ECOSUN Expert is always anticipating and implementing sustainable systems. Why? Because a park or plant well sized and well prepared in the present will always have a reason to exist tomorrow, beyond a service life of 25 years. 

Beyond this, ECOSUN Expert can also be the promoter of the widespread implementation of innovative systems such as the so-called positive energy ZI or energy production in isolated locations. How? Through association and collaboration with the competent authorities, for example Alsace Energivie or by associating with associations, local collectivities and national or international political authorities responsible for strategic projects.
