pv magazine Webinar | Surfing extreme winds: How 'Every-post self-locking' trackers eliminate torsional risks

As solar projects are increasingly deployed in regions with challenging wind conditions, the structural behavior of single-axis trackers is moving further into focus. Wind-induced vibrations and dynamic loads can not only affect the stability of the tracker structure itself but may also have long-term implications for PV module reliability. Excessive oscillations can contribute to the formation of microcracks in solar cells, potentially impacting module performance and lifetime.

In this webinar, pv magazine will take a closer look at ESET’s self-locking single-axis tracker technology, which has been developed to increase structural stiffness and reduce unwanted movement under strong wind conditions. The discussion will explore how the system works from an engineering perspective, how it is deployed in practice, and what lessons have been learned from real-world applications.

Fram Wang from ESET will present the company’s tracker concept and explain how the self-locking mechanism is designed to mitigate vibration and improve structural resilience. Parsa Enshaei from CPP will provide additional insight into the mechanical and aerodynamic aspects of tracker behavior under dynamic wind loads, including the potential impact of vibrations on PV modules. Max Dinkelaker from SBP will contribute further expertise on structural engineering considerations and project implementation.
Participants are encouraged to submit questions in advance or via live chat during the webinar.
