Learn how a solar panel hail impact test works, why IEC 61215 MQT 17 matters, and how a PV module hail tester helps evaluate module durability.

Photovoltaic (PV) modules are installed outdoors and are continuously exposed to rain, humidity, dew, condensation and other environmental conditions. Moisture can reduce the insulation performance of a solar module and may create electrical safety risks. The PV module wet leakage current test, also known as the wet insulation resistance test or wet leakage test, is designed to evaluate the electrical insulation performance of a photovoltaic module under wet operating conditions.

Learn how PV module mechanical load testing is performed, including module installation, positive and negative loading, load holding, inspection, and IEC 61215 MQT 16 testing.

The EN 1078 helmet impact test is an important safety test for bicycle helmets, skateboard helmets and roller skate helmets. The standard EN 1078:2012+A1:2012 specifies requirements and test methods for helmet construction, shock absorption, retention systems, field of vision and marking.

Learn how photovoltaic module EL inspection detects solar panel microcracks, broken cells and hidden defects using electroluminescence testing according to IEC TS 60904-13.

Bicycle helmet compliance testing is essential for verifying helmet safety and impact protection. Learn how EN 1078, CPSC 16 CFR Part 1203, and ASTM F1447 evaluate bicycle helmet performance and why a reliable Bicycle Helmet Impact Tester is important for compliance testing.

Learn how a Mattress Roller Testing Machine evaluates mattress durability, fatigue resistance, and long-term performance. Discover its working principle, applications, benefits, and compliance with EN 1957, ASTM F1566, and other international standards.

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.
