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.
