FAQ

What does the Photovoltaic Module Fracture Test Machine measure?

It evaluates the impact resistance of PV modules by simulating mechanical shocks from transport, installation, or environmental events. The system uses a weighted impact bag dropped from an adjustable height, filled with lead spheres to reproduce realistic impact forces. This allows precise assessment of module fracture tolerance and mechanical strength.

How is the impact load applied to the module?

The impact load is applied using a 45.5 kg impact bag filled with lead spheres (2.5–3.0 mm diameter). The bag is dropped from an adjustable height between 300–1220 mm. Compressed air assists smooth motion, and the force is controlled by bag weight, filling, and drop height, ensuring standardized and reproducible testing.

Can the test height be adjusted for different module sizes?

Yes. The impact height is adjustable from 300 mm to 1220 mm, allowing testing of modules of different sizes and strengths. The sample frame is also customizable to securely hold modules of various dimensions while maintaining safety and accuracy during the impact test.

What safety features are included in the machine?

Protective guard rails on both sides prevent personnel from entering the impact zone. The sample frame includes rubber strips to prevent damage to modules and reduce rebound risk. Operators are required to stay clear of the impact area during testing, ensuring safe and controlled operation.
