Effects of Wind on Solar Arrays: Not Just Hot Air

Effects of Wind on Solar Arrays: Not Just Hot Air

In some cases, the requirements have been surprisingly sparse, raising the concern that dangerously poor designs might find their way onto rooftops. Conversely, we’ve also seen exceedingly onerous requirements, begging the question as how anyone might afford to get a system designed, permitted and installed in certain jurisdictions. Neither of these extremes is healthy for the industry. Clearly, rooftop solar systems must be designed to handle the wind, snow and seismic loads appropriate each building and site. The challenge is that, while there are established snow and seismic load standards that can be applied to PV systems in a fairly straightforward manner, there is very little guidance on wind loads. Engineers and permitting officials have therefore been left with the choice of applying the building code in ways not intended or accepting designs based on wind tunnel t...
