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 every post 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.
Frank Wang from ESET will present the company’s tracker concept and explain how the every post 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.

Speakers
Parsa is an Associate Principal at CPP’s Sydney office, where he leads the firm’s solar capabilities across Australia and the wider region. With extensive experience delivering wind tunnel testing for major projects across Australia, Asia, and Europe, he has developed deep expertise in wind loads and aeroelastic effects on solar structures. Over his career at CPP, Parsa has worked with dozens of solar mounting structure manufacturers in China, India, and Europe, driving technical innovation and commercial growth in the sector. He regularly presents at national and international conferences and is an active member of the Australian Wind Engineering Society.
Frank Wang is the Director of Technical Support at ESET Solar’s Madrid Office. Backed by a U.S. Civil Engineering degree and over a decade of experience, he leads the technical engineering and strategic project delivery for utility-scale solar tracker solutions. Having successfully delivered numerous GW+ projects across Europe, LATAM, and beyond, Frank specializes in structural rigidity, aeroelastic stability, and the mitigation of torsional risks in large-format solar arrays.
He is passionate about translating ESET’s disruptive hardware innovations into highly bankable, field-ready solutions for global developers, EPCs, and Independent Engineers (IEs). Going beyond standard technical specifications, Frank successfully navigates strict international risk standards and complex CAPEX reduction goals to engineer the optimal structural solutions for global solar assets.
Max Dinkelaker (Dipl.-Ing.) graduated in Structural Engineering from Technische Universität Dresden, with a research focus on carbon-fibre tendons in prestressed concrete bridge designs. Since 2019, he has joined schlaich bergermann partner (sbp), Stuttgart, working on the structural design of long-span roof structures like Allianz Stadium Sydney (2022) and MHP Arena Stuttgart (2023). Since 2023, he leads sbp sonne’s PV Tracker Review Group, managing independent structural design reviews and incident investigations in PV/CSP projects. sbp sonne has reviewed a capacity of more than 50 GW of single-axis PV tracker installations world-wide, serving as mandatory independent reviewer for major developer around the globe.
