Steel ball impact test of photovoltaic panels
Simulated hail impact testing of photovoltaic solar panels
Techniques used to simulate and study the effect of hail on photovoltaic solar panels are described. Simulated hail stones (frozen ice spheres projected at terminal velocity) or steel balls were applied

Quality Assurance in solar thermal heating and cooling technology
There are two methods for impact resistance testing described in chapter 5.10 of EN 12975. One method is using a steel ball of 150g and dropping it on the collector surface to check the resistance. The
