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.

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

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.
