The fire safety test and certification were carried out by the Italian CSI Institute for the Testing and Certification of Materials and Products.
The fire test according to the UNI 9177 standard measures the flame spread on the sides of the PV modules. Depending on the result, the modules are classified into four fire protection categories. The double glass modules of SONNENSTROMFABRIK achieved the best values according to fire protection category 1, the glass foil modules of SONNENSTROMFABRIK fulfil the fire protection values according to category 2.
As part of the test procedure, the PV modules are exposed to a flame and a radiant panel. Based on the observations of flame spread, damaged area, dripping and flame formation, the material is then classified into one of four possible fire protection categories.
The monocrystalline SONNENSTROMFABRIK modules of the “EXCELLENT Glass/Glass” and “EXCELLENT Glass/Foil” series with 54, 60 cells and 72 cells thus stand for high performance and sustainability compared to the industry standard as well as for certified safety.
