A photovoltaic hydrogen production project located in North-West of China was hit by a level 13 sandstorm.
A large number of solar photovoltaic brackets collapsed, photovoltaic modules were damaged to varying degrees, and some modules were completely broken.
Relevant personnel said that the serious damage to the project was the result of the joint action of various influencing factors. On the day of the accident, the gust intensity reached level 13 or above, and the windy weather lasted for nearly 12 hours. At the same time, the project uses super-large photovoltaic modules, and the design of the support strength does not fully consider the wind load.
The reason for this accident is that the project developer did not purchase commercial insurance, and the manufacturer usually does not purchase additional commercial insurance for the manufactured products. lead to heavy losses.
In order to prevent possible losses, during the project bidding stage, some owners will specifically propose that the general contractor (EPC) be responsible for purchasing "project all risks" and clearly write it into the contract.
The various components used in this incident are not the first to come out, and it should be attributed to the lack of awareness of dealing with extreme weather and safety issues. For the construction of the project, it is not only about cost reduction, but also for safe and stable operation, it is necessary to thicken the component glass, strengthen the bracket material, deepen the piling, and take into account both cost and project safety.
