PV Hail Impact Tester

The PV Hail Impact Tester is a precision instrument designed to evaluate the mechanical resilience of photovoltaic modules under simulated hail impact conditions. It delivers controlled and repeatable impact energies to assess module durability, ensuring compliance with international IEC, UL, and ASTM standards. The system supports both laboratory testing and quality control in production lines, providing high-speed imaging and automated data logging for comprehensive performance analysis.

Application

The tester is suitable for:

Quality control of photovoltaic modules during production.

R&D for new PV module designs and materials.

Verification of hail resistance under extreme weather conditions.

Certification testing in compliance with IEC, UL, and ASTM standards.

Standards

IEC 61215: Mechanical load testing for terrestrial photovoltaic modules

UL 61730: Safety standards for photovoltaic modules under extreme weather conditions

ASTM E1886: Impact resistance testing for building envelopes (adapted for PV applications)

IEC TS 63057: Hail impact simulation protocols for concentrated solar power systems

Features

Precision Engineering: High-speed pneumatic system with ±2% accuracy delivers consistent impact energies.

Adjustable Simulation: Ice ball diameter adjustable from 25 mm to 75 mm to simulate diverse hail sizes.

Safety Assurance: Enclosed chamber with transparent polycarbonate shielding, emergency stop, and over-pressure protection.

User-Friendly Operation: 7” touchscreen HMI with multi-language support and pre-programmed test modes.

High-Speed Imaging: 1000 fps camera captures impact dynamics for post-test analysis.

Automated Control: Programmable ice ball trajectory (0°–90°) and real-time force, velocity, and deformation data logging.

Robust Construction: Stainless steel frame with anti-vibration mounts and low-noise operation (<65 dB).

Customizable: Optional environmental chamber (-40°C to +85°C) for temperature-dependent impact testing.

Test Procedures

Install PV modules securely in the dual-station clamps.

Select ice ball size and impact energy through the touchscreen HMI.

Set test parameters, including trajectory angle (0°–90°) and optional environmental temperature.

Initiate the automated impact sequence.

Monitor high-speed camera footage and real-time data logging for force, velocity, and deformation.

Review test reports and export results for documentation or certification purposes.

Maintenance Information

Inspect ice ball launcher, pneumatic nozzles, and clamps before each test session.

Clean the testing chamber and polycarbonate shielding regularly to ensure visibility and safety.

Check and replace O-rings, pneumatic fittings, and ice balls as needed.

Ensure air compressor delivers stable pressure within 0.6–0.8 MPa.

Periodically calibrate sensors and high-speed imaging equipment according to manufacturer guidelines.
