PV Module Hail impact tester with IEC61215-2:2016 testing

PV Module Hail Impact Tester with IEC61215-2:2016 testing

Standard
It's according to IEC61215-2:2016 the newest testing standard

Purpose
It's to verify that the module is capable of withstanding the impact of hailstones

The Technical specifications
