In photovoltaic power station projects, the support structure is the "framework", while the panels are the "skin". Once there is a defect in the design of the support structure, even the best components of the entire system may fail. One of the most frequently asked questions by customers is: Can the photovoltaic support structure withstand extreme strong winds?
In fact, the wind resistance performance of the support structure is not only determined by the thickness of the steel, but also by the cross-sectional design and connection nodes. If the opening angle of the crossbeam is too large, it is prone to form an "air inlet" under the action of strong wind, thereby amplifying the force. For example, if the position of the bolt connection is not arranged reasonably, it is likely to loosen after long-term tension.
In some engineering cases, when the wind speed exceeded 25m/s, the support structure tilted overall and had to be reworked. This shows that even a 5-millimeter deviation in the installation hole position can cause the bearing path to change, thereby affecting the overall wind resistance effect.
Therefore, when purchasing the forming equipment for photovoltaic supports, customers should not only check whether the equipment can produce qualified cross-sections, but also ask more questions: During the design stage, how to control the stability of the cross-sectional formation? How to ensure the repeatability accuracy of the hole spacing and angles?
