Q1: Are flexible panels still a 2-year product “disposable”?
No, it’s an old stigma from the PET era. Advanced ETFE modules from leading manufacturers carry a 10-year warranty and are designed for extreme weather.
Q2: Can flexible panels handle hail?
Yes, professional grade flexible panels pass the same IEC 61215 impact test as rigid panels. Their polymer surface actually absorbs some of the impact energy that breaks the glass.
Q3: Which salt spray is better for the (marine) environment?
Flexible win. The lack of an aluminum frame eliminates the primary site for galvanic corrosion, making it an excellent choice for yacht and coastal off-grid sites.
