devoted collaborators

The client at the center of its philosophy

The photovoltaic energy appeared in the 1990’s but really improved at the beginning of the 21st century when this energy source started to democratize.

In spite of the mistrust that affected this technology in the past, photovoltaics has the largest technical potential in terms of profitability and sustainable development. The result is clear: nowadays we are all concerned by global warming and the use of renewable energy.

Since its beginning, the SUNERGIS leading team wants to break with the usual codes of its line of business:

By legally and commercially protecting the client: the classic contract signature process is completed following specific formalities.
By building its team with a technical office and industry professionals, SUNERGIS can optimize the quality of its advice and the usefulness and the profitability of a project.
