Learn what an EL tester is, how electroluminescence testing works, and why it is essential for detecting hidden defects in photovoltaic (PV) modules. Improve solar panel quality with professional EL testing equipment.

The IEC 61215 standard addresses this threat through MQT 17 (Hail Impact Test), which verifies that solar modules can withstand real-world hail strikes. After testing, panels must show no serious appearance defects, less than 5% power degradation, and pass insulation resistance tests.

Learn how hail impact testing helps evaluate solar panel durability and ensure compliance with IEC 61215 standards. Discover the importance, testing process, and applications of Hail Impact Test Equipment for photovoltaic modules.
