IEC requirements dictate that passing the mechanical load standard is essential for solar modules. With modules increasing in size, mechanical load considerations are taking on a higher profile, meaning that responding to and exceeding the industry standard to achieve better mechanical load value has become a major focus of JinkoSolar’s Tiger Pro series.
The company continues to optimize the material and process design of its frame to ensure that the module itself can withstand wind and snow pressure when the system is compatible and the BOS is lower. In terms of reliability, Tiger Pro has not only passed the IEC standard mechanical load test of 5.400pa on the front side and 2,400pa on the rear of the fixed racks, but JinkoSolar also considered the matching of modules with trackers of different brands to guarantee the safety of the module mechanical load in order to improve compatibility with different installation conditions.
Ensuring bankability while guaranteeing reliability and safety
Taking a 300MW DC project + tracking bracket in Australia as an example
In terms of compatibility testing of modules and mounting system, the project requires the mechanical load of the external, internal and edge of the system to withstand 2,400pa.
Considering the difference in maximum load value that the screw hole position of 182mm and larger modules can withstand, in this project the mechanical load value has exceeded the maximum that the larger size module can bear, resulting in an increased cost of the purlin of the mounting system. On the other hand, with its excellent mechanical load performance, the Tiger Pro 182mm series can save nearly 0.7% of the BOS cost per watt.
Accordingly, the mechanical load value of the module should not be underestimated. JinkoSolar’s Tiger Pro 182mm module can optimize BOS costs with its advantages on mechanical load and, due to its high power output and existing market acceptance globally, it may be considered the best module selection in 2021, helping PV projects to reduce costs and increase efficiency.
