A large-scale agricultural storage facility

The solar power plant located on the buildings of the “Domaine du Grand Estagel” in the town of Saint-Gilles in the Gard is part of a winning projects from the 2nd period of the call for tenders from CRE4. It is worn by the Langa company.

For this project, Langa chose the supplier GCL (with the local support of SYNAPSUN) to equip the roofs with low carbon solar panels.

The GCL P3 / 72 H 385 module model is perfectly suited to this type of construction. This is a large module with half cells for better shade management.

This installation of 5,517 photovoltaic modules for a total power of 2.39 MWp, should produce some 3,060 MWh each year
