In a few words

Cefem Solar

A company develops according to its knowledge and resources, in parallel with the needs of tomorrow, but also according to its values. In 2010, the Cefem Group, with its wealth of experience in power electronics, decided to enter the photovoltaic market. It is also a rural, family-run SME, but one that is open to the world, and as such intends to defend the environmental convictions to which it is committed. Solar energy was therefore an obvious choice.

Cefem Solar was created in 2009 from the sum of the Cefem Group's skills and values. The Business Unit was able to benefit from the Group's strengths: production tools, quality, R&D, etc. to develop its range of grid-connected inverters.
