6 FAQs about [HJ Solar Panel Hail Test]
Do PV modules need a hail resistance test?
For the qualification of PV modules in accordance with the IEC 61215 and IEC 61646 standards, the hail resistance test is mandatory. Chapter 10.17 of the standard describes the launching equipment and the measurement instrumentation, but is somewhat lacking in the definition of the hail grain quality.
Can a PV module withstand a hail impact?
Damage impact. The module was tested with a speed of up to ture of -18°C and an incident angle of 90°. 3.3. Discussion front glass are highly resistan t to hail impact. The general past five years of activity has confirmed this. One issue aged the PV cells. Since this damage occur red only at a less practical importance.
What is a hail test?
A hail test is traditionally used to qualify a PV module at IEC level (IEC 61215-2, MQT17) and is defined as 25 mm diameter and 80 km/h speed. Swiss standards, issued by the VKF (Vereinigung Kantonaler Feuerversicherungen, association of cantonal fire insurers), are more demanding because of the particular conditions of the environment.
How strong should a PV module withstand a hailstone?
According to IEC 61215 standard, a PV module should resist at the minimum to the impact of a hailstone of 25 mm launched at 80 km/h, while the Swiss VKF standard demands a minimum of 30 mm, practically making it 40 mm or more.
