The Sandbag Mechanical Load Testing Machine is a precision instrument designed to assess the mechanical load-bearing capacity of photovoltaic (PV) modules under static and dynamic conditions. By combining sandbag static loads with dynamic pressure from low-friction cylinders, it simulates wind, snow, and ice loads. This enables accurate evaluation of compressive strength, structural stability, and overall reliability, ensuring PV modules perform safely under real-world environmental conditions.
Standards
The machine is designed to comply with international and domestic PV module mechanical testing standards:
GB/T 9535 series – Mechanical Load Testing of Photovoltaic Modules
IEC 61215 – Crystalline Silicon PV Module Design Qualification and Type Approval
IEC 61646 – Thin-Film PV Module Design Qualification
IEC 62782 – Mechanical Load Testing of PV Modules under Snow and Wind
UL 1703 – Safety Standard for Photovoltaic Modules
