Photovoltaic module hail impact testing machine
Category：Other
Introduction
The Photovoltaic Module Hail Impact Testing Machine is designed to evaluate the resistance of PV modules to hail impacts. Using standardized artificial ice balls launched at controlled velocities, it simulates natural hailstorms, assessing the module’s durability against glass breakage, cell cracks, or power loss. This ensures long-term reliability for PV modules under extreme weather conditions.
Applications
This machine is suitable for:
Quality assurance during PV module manufacturing
Certification and type testing for international standards
R&D evaluation of module structure and materials
Failure analysis after extreme weather exposure
Comparative testing of different PV designs
Typical evaluations include surface cracking, electroluminescence (EL) imaging, power output degradation, and lamination integrity.
Applicable Standards
The system complies with:
IEC 61215 — Crystalline silicon PV modules
IEC 61646 — Thin-film PV modules
UL 1703 — Flat-plate PV modules and panels
Compliance ensures globally recognized, reliable testing results.
