The Mechanical Load Testing Machine is a precision instrument designed to evaluate the mechanical load-bearing capacity of photovoltaic (PV) modules under static and dynamic conditions. It simulates wind, snow, and ice loads through dynamic pressure technology, providing reliable assessment of module structural integrity, compressive strength, and deformation resistance. The machine ensures PV modules perform safely and stably in real-world environmental conditions.

Standards

The machine is designed to meet key international and domestic PV module mechanical testing standards:

GB/T 9535 series – Mechanical Load Testing of Photovoltaic Modules

IEC 61215 – Crystalline Silicon Photovoltaic Module Design Qualification and Type Approval

IEC 61646 – Thin-Film Photovoltaic Module Design Qualification

IEC 62782 – Mechanical Load Testing for PV Modules under Snow and Wind

UL 1703 – Safety Standard for Photovoltaic Modules
