Dynamic Mechanical Load
Dynamic mechanical load occurs when PV modules sway under strong winds, causing alternating positive/negative pressure. This accelerates material fatigue and may damage cells or gridlines. Key factors include module size, thickness, surface treatment, frame stability, installation method, and weld reliability. Testing evaluates fatigue resistance and material durability to enhance product quality.
Static Mechanical Load
Static mechanical load per IEC 61215 must reach ≥1.5× design load. By applying load and measuring displacement/stress, it determines max load capacity and deformation traits—key for selecting and designing PV components that reliably withstand real-world mechanical stress.
Significance of Mechanical Load Testing
As PV modules grow larger and more powerful, they face increasing mechanical stress during handling, transport, installation, and from environmental loads like wind and snow..
Insufficient strength can cause excessive deformation, leading to cell and gridline failure.
