Nathalie Kermelk, European product director at Clenergy, will introduce the latest version of the D1P120 tracking technology, which employs a patented multi-drive architecture to synchronize up to four motors under a manager-worker control system. According to the company, each of these motors can provide real-time angular feedback. This ensures precise unison across an entire solar module row and mitigates, or even eliminates, torsional stress and prevents torque tube twisting, which could result in damages for the PV facility. Clenergy says the system can achieve a 200% higher aeroelastic stability and reduced vibration and structural fatigue, as well as extending the trackers’ lifecycle.

Furthermore, Parsa Enshaei, associate principal at CPP, will outline how wind tunnel models and torsional instability testing are conducted, supported by videos and examples of 2D and 3D modelling. He will also provide insights on interpreting test results, applying mitigation methods, and delivering site-specific design recommendations to enhance tracker resilience.

In the third part of the webinar, Juan Esquivel, solution manager at Clenergy, will discuss how to translate wind test data into practical engineering solutions. He will share success stories from projects in Hungary, China, and the German Alps, highlighting unique site requirements and tailored design approaches.
