Prefalz Solar Panel

Prefalz Solar Panel

NEO | METAL
Brand: PREFA®
PREFALZ Solar Panel combines aesthetics and performance with glass/glass PV modules specially developed for standing seam roof systems. Thanks to its roof-parallel installation and low build-up height, it preserves the architectural lines of the building. The one-piece clamp system is fixed directly onto the standing seams, eliminating any roof penetration. Durable TOPCon cell technology ensures high efficiency, fast installation, and retrofit compatibility. Developed in Austria, the system delivers long-lasting and sustainable energy with PREFA quality.
