About TSE
TSE: a leading independent solar energy producer
Créé en 2016, TSE est un des principaux acteurs indépendants de l’énergie solaire en France. Développeur de centrales solaires et de solutions agrivoltaïques, TSE est expert en photovoltaïque et un des leaders de l’Agri PV.
Our goal is to meet the challenge of the energy and ecological transition through our two sectors of activity:
Our expertise
We carry out the entire value chain of a solar plant, from the design, financing, construction, and supervision to the operational management, in order to convert solar energy into electricity.
Project identification
and security

We carry out and finance all of the feasibility studies needed for a project. We work with all the stakeholders involved to define the best possible location for the project. Our teams handle administrative procedures with the relevant authorities (filing building permits, etc.).
Financing
We set up financing for the project with our financial partners and submit the project to an invitation to tender of the French Energy Regulatory Commission (CRE) if eligible.
Construction

Once commissioned, we operate the plant and carry out preventative and corrective maintenance by way of our maintenance teams located throughout the country.

and recycling
and recycling
At the end of a solar plant’s life cycle, we decommission the plant and restore the land to its previous state. We subscribe to PV Cycle, an organisation that organises the collection and recycling of end-of-life solar panels, when we purchase the panels. Solar panels are nearly 95% recyclable.
