Other

The Mechanical Load Testing Machine for Photovoltaic Modules is designed to evaluate the structural strength and durability of PV modules under simulated environmental loads. It replicates snow, wind, hail, and debris impact conditions by applying precise forward, reverse, and dynamic mechanical loads, ensuring modules meet global reliability and certification requirements.

This machine is essential for PV module manufacturers, testing laboratories, and R&D teams seeking to verify mechanical performance and prevent field failures.

Applications

The system is widely used for:

PV module design qualification and type approval

Structural durability testing under snow and wind loads

Dynamic fatigue testing simulating hail and debris impacts

Quality control and batch testing during PV manufacturing

R&D for framed, frameless, and flexible PV modules

It helps detect glass cracks, cell breakage, frame deformation, and lamination issues before field deployment.

Applicable Standards

The machine is fully compliant with international standards:

IEC 61215 – Terrestrial PV Modules: Design Qualification and Type Approval

IEC 61646 – Thin-Film PV Modules: Design Qualification and Type Approval

IEC 62782 – Dynamic Mechanical Load Testing for PV Modules

UL 1703 – Flat-Plate PV Modules and Panels

CE Certification – Conformité Européenne

Compliance ensures globally recognized, reliable, and repeatable testing results.
