  • According to the latest dynamic and static load tests, Longi Hi-MO 5 solar panels has performed extremely well in both the stiffness and resistance to extreme wind speed damage, deformation and crack. 
  • LONGi Solar is a world leading manufacturer of high-efficiency mono-crystalline solar cells and modules.

As a product working for 25 years or even 30 years, generating electricity continuously for PV module is essential to maximize the value of customers. Therefore, the module should be designed in consideration of the ability to resist extreme climate throughout the full life cycle.

At 45 m/s Wind Speed Test Oversized Bifacial Module Failed, and the Large-size Bifacial Module Passed 60 m/s Wind Speed Test

To verify the ability of the module to resist external mechanical stress, LONGi and TÜV NORD jointly carried out a wind tunnel test to verify the ability of the module under a dynamic load, and LONGi also carried out a static load test on the large-size module (LONGi Hi-MO 5, 2.26×1.13m) and the oversized module (2.38×1.30m) to simulate the bearing capability of the module under outdoor snow load.

The test results showed that the stiffness of both monofacial and bifacial Hi-MO 5 is better than that of the oversized modules and can pass the thresher test at the wind speed of 60 m/s. The static load test showed that the deformations of both monofacial and bifacial Hi-MO 5 modules are less than 45 mm, and their anti-crack abilities are excellent.

The series of tests ensures the reliability of Longi solar panels which can effectively cope with “once-in-a-century” hurricane or blizzard throughout the life cycle. The resilient character and quality of the product brings long-term reassurance of performance and safety to power plants.

Green Building Africa promotes the need for net carbon zero buildings and cities in Africa. We are fiercely independent and encourage outlying thinkers to contribute to the #netcarbonzero movement. Climate change is upon us and now is the time to react in a more diverse and broader approach to sustainability in the built environment. We challenge architects, property developers, urban planners, renewable energy professionals and green building specialists. We also challenge the funding houses and regulators and the role they play in facilitating investment into green projects. Lastly, we explore and investigate new technology and real-time data to speed up the journey in realising a net carbon zero environment for our children.
