The KW3 is designed and manufactured in France by the company Libre Énergie.

Libre Energie

Libre Énergie is a firm founded in 2007 that specializes in consulting, studies, and the promotion and implementation of renewable energy production systems :

  • photovoltaic,
  • wind,
  • thermodynamic solar,
  • and micro-cogeneration systems.

The cost of energy constitutes a major stake for the competitiveness of businesses. The price of electricity is going to increase significantly in the years to come.
Libre Énergie’s teams, which were trained at the INES (French National Solar Energy Institute) and by Les Compagnons du Solaire (a solar energy sector training school), want to enable everyone to have the possibility of producing their own electrical energy whilst protecting the environment and maintaining a sustainable economic balance.

Libre Énergie is a member of the association Novabuild which, over the years, has established itself as the benchmark network for actors in the eco-construction sector in the Pays de Loire (industrial firms, consultancies, architectural firms, researchers, etc.).
