Creative Single Rotary Axis Solar Tracker System, France
Nexans Solar Technologies is an internal branch of Nexans, created in 2018 as part of the transition plan towards renewable energies, which aims at providing solutions, products, and services to energy producers and investors.The solar tracker from KEYLIOS® is the first solution entirely conducted by Nexans Solar Technologies, from design to manufacturing. A major contract had already been signed with a prominent developer of photovoltaic projects and an energy supplier providing more than 800 of these solar trackers to be established on four solar facilities located in the southwest of France.

Nexans Solar Technologies' objectives are, among many other things, to contribute to the rise of solar energy in fields and areas where such resources are barely accessible due to hills too steep to build upon (for example) or foundations considered to be too expensive, even previously impossible. Old landfill sites, brownfields, and old quarries extending to hilly or unstable ground are also relevant examples. The solar tracker from KEYLIOS® revolutionizes the profitability of competitive solar facilities established in areas which had not previously been considered to be suitable for trackers due to the excessive installation cost.
Design and Features
A solar tracker maximizes the orientation of its solar panels thanks to its intuitive rotating system in order to have a higher energy yield, as opposed to fixed solar structures.
This lightweight truss structure designed by Nexans Solar Technologies allows construction in areas that were considered incompatible for traditional trackers (barely accessible areas, polluted soil, unstable ground, and so on). Deployment in remote or barely accessible areas is possible not only thanks to its pre-assembled modular design, but also thanks to its foundation system, which only requires 4 support zones, defined by two foundations for the entire structure, which can be of any type, such as bored piles or concrete blocks.
Moreover, the solidity of the structure allows operation in a wide variety of climatic conditions. It also displays a remarkable resistance to strong wind and destructive aerodynamics.
Optimization and rigorous control of production costs led to the choice of RFEM Software, on which the structure of the KEYLIOS® tracker was designed.
For the purpose of meeting customer requirements and to provide a customized tracker solution, a prototype designed in RFEM was configured in order to automatically generate an end-customer model - an automated calculation process conducted according to the client's expectations.
In the basic structural model, the self-weight was entered manually on each element, and the combinations involving different wind loads enabled loading decline as well as the design of components shaping the overall structure.

"The RFEM software allowed us to accurately model the solar tracker with nonlinear calculation and the integration of very specific stiffnesses on the connections.
The RF‑STEEL EC3 add-on module, which designs the elements according to Eurocode 3, was also very useful for the optimization of the structure.
Furthermore, the extraction of various parameters of the model or of the results (forces and nodal displacements) facilitated the automation of the modeling process of the tracker and saved a considerable amount of time.
The support provided by Dlubal was a great help in the realization of this project.
Besides the rapid response to our questions, Dlubal has provided us technical solutions to improve our model."
CSA S16:19 Stability Considerations and the New Annex O.2
The CSA S16:19 Stability Effects in Elastic Analysis method in Annex O.2 is an alternative option to the Simplified Stability Analysis Method in Clause 8.4.3. This article will describe the requirements of Annex O.2 and application in RFEM 6.
- The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
