We recently completed a solar project in San Marcos, TX using Solar Stack to mount the system to a cold storage metal roof. Down the street, a similar project was completed using traditional metal roof clips and rail attachments. Shortly after, a tornado and severe hailstorm hit the area. The results were eye-opening: while the neighboring system with the clip and rail method was partially ripped off the roof, the Solar Stack system we installed held firm without any damage. This experience has given us full confidence in the Solar Stack solution for its superior durability and resilience, even in extreme weather conditions. We highly recommend Solar Stack for anyone seeking a reliable, long-lasting solar mounting system.
