PV in need of a new chapter for wind

In part two of this feature on wind resilience in the PV industry, the lack of structural codes comes into focus. Weather events, and wind above all, are the most common causes of failure for PV plants. In the United States, the first steps have been taken to catch up with other industries and a dedicated chapter for PV is set to be included in the next update of the American Society of Civil Engineers code. In Europe, no such plans are in place.

However, the testing methodology for PV is not yet standardized. Skyscrapers must undergo dynamic wind load testing, but PV arrays do not ... even though many argue that this is a dangerous fallacy.
