Summary / Abstract: Single incidents in the field having indicated mechanical damage to modules, such as cracked glass and bent alloy frames, induced by snow loads, an experimental study was conducted at the TÜV Rheinland laboratories to simulate such load effects. In accordance with IEC/EN 61215 or 61646 we applied mechanical snow loads uniformly in the range of 2400 up to 5400 Pa with the module oriented horizontally. The work presented here illustrates the theoretical aspects and the practical application of inhomogeneous snow loads on inclined PV modules. The purpose of this research is to estimate the effects on the rigidity of modules by applying two-dimensional mechanical loads at an inclination. The test results form the basis of a TÜV Rheinland internal testing method for the qualification of PV modules under inhomogeneous snow loads.
