Simply put, it's a measure of how well a structure can withstand the force of the wind. For pitched roof PV brackets, this rating tells us how much wind pressure the brackets can handle before they start to fail. This technical note further. . Understanding the wind resistance rating is crucial for ensuring the safety and longevity of photovoltaic (PV) systems, especially in regions prone to high - wind conditions. These structural supports typically withstand wind speeds between 90-150 mph (145-241 km/h), but actual capacity depends on multiple engineering factors.

By taking reference on the windspeed table below, we can understand pascals pressure on the solar structure and modules. Modules level- wind load Referring to the data sheets of most solar modules, it's evident that they typically withstand up to 2400pa, equivalent to approximately 62.52m/s wind uplift force.
Many solar structure suppliers often claim that their systems can withstand high winds up to 85 m/s. However, this is frequently not true. Different solar clamps, roof profiles, materials, or thicknesses can yield varying results in the ultimate load profile. To justify such statements, manufacturers should provide test reports.
Therefore, when customers or government guidelines mandate designing a solar structure to endure higher winds, like 72m/s, equating to about 3200pa, the warranty coverage from the solar modules has already peaked. Consequently, in cases of high wind loads, the module supplier wouldn't be held liable. Solar structure – wind load
Currently, there are no codes and standards mandating pullout tests on actual roofs to confirm wind uplift resistance. Therefore, we recommend the following: Solar Structure Testing: Conduct tests in an ISO 17025 certified lab. Pullout Anchorage Test: Test in at least two load directions—negative normal and parallel to the roof.
