Presentation These glass/glass photovoltaic modules have been developed specifically for PREFALZ standing-seam roofs and integrate with the characteristic appearance of the standing seams. The system pairs double-glass PV modules with integrated fastenings (clip + module clamp) enabling installation parallel to the roof with a minimal mounting height of 70 mm.
Benefits- Aesthetics: parallel to the roof, preserves the look of the standing seams and integrates harmoniously with PREFALZ roofs.
- Durability: robust glass/glass module resistant to moisture, hail and snow loads.
- High efficiency: TOPCon cells deliver approximately 10% more power, including improved performance in diffuse light.
- No penetrating the roof covering: attachment to standing seams via special clamps transfers loads without damaging the covering.
- 2-in-1 fixation: clip and module clamp combined in a single product for simplified assembly and fewer components.
- Suitable for new or existing PREFALZ roofs.
- Produced and developed in Austria (PREFA industrial quality).
Cell technology TOPCon photovoltaic cells: improved lifetime and heat dissipation, higher efficiency (~10% vs PERC), better performance in diffuse light.
