A prototype 120-cell/500 Wp solar photovoltaic (PV) COSMOS module from TULiPPS Solar B.V. was subjected to the punishing Module Breakage Test three times at maximum impact height by independent solar-module testing and certification organization, Kiwa N.V. at facilities in Legnano/Milano, Italy. Despite three hits by a 45.5-kilogram/100-pound ball suspended 122 centimeters/48 inches from the module, the unit’s glass did not break. This was an exceptional result because the Module Breakage Test — a safety test that simulates a worker falling onto the unit during installation or maintenance — is designed to destroy a module in order to see how the protective glass front fragments.
In addition, Kiwa subjected a second 120-cell/500 Wp solar photovoltaic (PV) COSMOS module from TULiPPS Solar B.V. to the Hail Impact Test. The unit was bombarded with ice balls that were 25 mm/1.0 inch in diameter and that weighed 7.5 grams/0.3 ounces from a pipe mounted 0.5 meters/20 inches from the module. Three areas deemed “most severe” (center and edges) were impacted at 5x higher impact energies than are normally used for certification testing. At the end of the test, not only was the module fully intact, but there was zero output loss measured after Flashing the unit. Further, Electroluminescence testing showed there was no breakage or microcracking in PV cells protected by the glass, which likely indicates the glass can withstand higher impact energies and still protect cells. TULiPPS uses special 2-mm/0.08-inch toughened solar glass from Ducatt NV produced via the patented tempering process developed by LiSEC Group. Although half the thickness of glass typically used on conventional solar modules, this ultra-thin glass proved to be exceptionally durable.
