Test Procedures

Mount the PV module securely on the test fixture.

Set the desired peeling angle (0–180°) and test speed (50–500 mm/min) on the digital display.

Apply the rated load to initiate the peeling test.

Monitor real-time force and displacement via the digital display.

Record the maximum stripping force and peeling behavior data.

Repeat the test for multiple samples as required for statistical validity.

Analyze the results to evaluate backplane adhesion strength and consistency.

Maintenance Information

Regularly inspect clamps, fixtures, and load application components for wear or damage.

Calibrate digital display and load sensors periodically to maintain measurement accuracy.

Keep the test area clean and free from dust or moisture to prevent contamination.

Lubricate moving parts and guide rails as recommended by the manufacturer.

Store the machine in a dry, temperature-controlled environment when not in use.

FAQ

1. What is a Photovoltaic Module Backplane Peeling Strength Testing Machine?

This machine is used to measure the adhesive strength between the backsheet and other layers of a photovoltaic (PV) module. It ensures that the layers remain bonded under mechanical and environmental stresses.

2. How does the peeling strength test work?

The tester grips the backsheet and the PV module layers separately, then pulls them apart at a controlled speed and angle. The force required to peel the layers apart is measured and recorded.

3. What types of PV modules can be tested?

It can test various photovoltaic modules, including monocrystalline, polycrystalline, and thin-film solar panels, with different backsheet materials such as PET, PVF, and composite laminates.

4. What parameters are measured during testing?

The machine measures peeling force, peeling strength (N/mm), elongation during peeling, and mode of failure (adhesive or cohesive). Some models provide real-time data logging and graphical analysis.
