About TSE
TSE: a leading independent solar energy producer
Founded in 2012, TSE is one of the primary independent solar energy companies in France. As a developer of solar energy power plants and agrivoltaic solar solutions, TSE is an expert in photovoltaics and a leader in agriphotovoltaics.
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.

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.
