Scope

This document describes a testing method for determining the mechanical performance of framed photovoltaic modules under the influence of tilted non-uniform snow loads.
This document is applicable to framed photovoltaic modules, whose frames protrude beyond the front panel glass surface of the modules after intended installation, thereby providing additional resistance to snow sliding off the module surface. This document is not applicable to modules with other frame structures, such as those where the frame forms a rear frame structure or those whose side, top, or bottom frames do not provide additional resistance to snow sliding off the module surface.
