HIT - Hail Impact Tester

Hailstorms can cause severe damage to modules and collectors. Our test stand enables you to carry out tests according to international standards. The hail impact test stand uses an air-pressurized launcher which shoots ice balls representing hailstones of a predetermined size at the module or collector mounted on the support frame. 

The hail impact tester is a pneumatic launcher which propels uniformly manufactured ice balls at thermal collectors and PV-modules.
