Have you ever wondered how unused land and brownfield sites can be reclaimed? We have the solution. We are the first company to offer the possibility of combining bituminous geomembrane with flexible photovoltaic modules, such as Excel Solar. This solution makes it possible to reclaim unused and lost spaces such as closed landfills or brownfield sites while supplying electricity to buildings or companies.

This is good for the environment and a great way to reclaim space impacted by human activity!

The pictures show a site where 3500 m² of COLETANCHE was installed and topped by flexible EXCEL SOLAR 400 PV modules of 130kWp each.
