Comprehensive testing at every stage has been vital to the solar industry’s impressive growth to date – investors, insurers, and other project stakeholders all need some assurance that this still young technology can live up to expectations, particularly when those expectations are centered around the entire system being installed outdoors and left to the elements for a lifetime of 20 years or more.

When it comes to trackers, proving reliable wind resistance is among the most vital of these tests. However, a closer look at common wind loading standards reveals that they do not accurately represent the way the wind loads the module. In this pv magazine Webinar, we’ll look at this in detail, as well as how bifacial and large format modules impact the maximum wind speed that can be supported by the modules and tracker system.

We’ll be joined by Yarrow Fewless, CPP Wind Engineering, who will demonstrate how the wind pressure PV systems are under in the field often does not match with what they’re tested against, leaving the door open for costly failures after installation.

Following on from Yarrow; GameChange Solar’s Scott Van Pelt will take us through their module testing procedure that more accurately simulate the distribution of stress caused by wind in the field, and how findings gained from these have influenced the design of the company’s latest tracker system.

Finally, Daniel Chang of RETC will share his expertise on different combinations of module and racking system, and how the latest round of module technology upgrades – in particular bifacial and the switch to larger formats – affect how the mechanical rating of the system and therefor the maximum wind speed it can support.
