Typhoon Bavi Approaches: How Should Photovoltaic Modules Prepare? Wind Tunnel Data for Preparation

According to the China Meteorological Administration, Typhoon Bavi, the 9th typhoon of the year, has strengthened to over Category 17 (central wind speed 62 m/s) and is approaching the coast of East my country. It is expected to make landfall on the border of Zhejiang and Fujian provinces on July 11-12. Coastal areas of Zhejiang, Shanghai, Jiangsu, and Fujian will receive a red storm surge warning.

As one of the strongest typhoons in recent years, it poses a severe test to the structural safety of photovoltaic power plants in East China. Extreme wind pressure can cause frame failure, leading to a sharp increase in the risk of module damage and microcracks in the cells. At best, the power plant will experience reduced power generation; at worst, it will be completely scrapped. With typhoon season upon us, the selection of photovoltaic frames needs to withstand the test of extreme weather.

Hongsheng Composite Materials Frames: Responding to the Challenges of Extreme Environments with Authoritative Testing Data

Frames, as important auxiliary materials for photovoltaic modules, play crucial roles in fixing and sealing. How to securely fix the modules to the mounting bracket with high strength has always been a major challenge in the development of composite material frames. Hongsheng's specially designed reinforced insert installation perfectly solves the above problems, and this has been verified through rigorous load testing and wind tunnel testing.

The following are the load test data completed by a third-party testing agency commissioned by Hongsheng:

· Installation method: Special reinforced insert installation

· Test component: BC component with dimensions 2382×1134×B30

· Static load: 6300Pa / 4300Pa

· Dynamic load: ±1500Pa, 3000 cycles

· Wind tunnel measurement: 65.1m/s on the windward side, 52m/s on the leeward side

Why are composite material frames more suitable for typhoon-prone areas?

Compared to traditional aluminum alloy frames, glass fiber reinforced polyurethane composite material frames have unique performance advantages:

· Higher strength: The tensile strength of the composite material frame is more than 5 times that of aluminum alloy.

· Excellent fatigue resistance: Less prone to residual deformation under repeated positive and negative wind pressure from super typhoons.

· Strong corrosion resistance: More stable in coastal high-salt spray environments, reducing the risk of component failure due to frame corrosion throughout its entire life cycle. It is worth emphasizing that the high strength and fatigue resistance of the composite frame enable it to maintain structural stability under repeated wind pressure, making it more reliable in the long term compared to traditional aluminum alloy frames—this is especially important for power plant selection in typhoon-prone areas.
