We provide expertise in the design of foundations for all types of ground-based photovoltaic panel projects. Our studies are adapted to the geotechnical conditions of the site and to the connection system of the steel structure. We also take into account the local and international standards as well as specific guidelines which can be applied to large fields with photovoltaic structures. We have worked for several clients,installing different types of trackers and modifiable struc- tures on difficult terrain and old landfills. “TOUL-ROSIERES”SOLAR FARM Location: Toul-Rosières Air Base,France (54) Year: 2011 (in progress) Client: Krinner Schraubfundamente GmbH Manufacturer: Krinner Schraubfundamente GmbH Site manager: EDF EN Superficy: 400 ha,143 MW Project description : For this solar farm CTE performed the preliminary design and implementation studies for the panel structure. This project had the following characteristics: The project was divided into 5 panel units of 12 MW each.The calculations were adapted to the geotechnical conditions of each panel unit The PV panels are fixed in the ground with screws (no foundation) Variable water level Photovoltaic power stations Our know-how Example of a study in France
