WEB EXCLUSIVE: The new Aixtralight Clip rooftop solar-panel mounting system from Germany’s Aixtra Solar AG is made of ultra-stiff, 35% glass-reinforced, flame-retardant Ultramid A3WG10 nylon 66 from BASF (U.S. office in Wyandotte, Mich.). The plastic bracket is mounted on a roof, and the rails attached to the photovoltaic modules can be quickly and easily inserted into the bracket.
Installing an Aixtralight Clip is said to avoid stresses caused by differences in the expansion coefficients of the trapezoidal sheet metal and the mounting rails. The ultra-stiff nylon exhibits minimal creep tendency at temperatures up to 80 C as well as extraordinary toughness at low temperatures. Also, the nylon easily handles long-term direct contact with PVC roof membranes and conforms to the B2 fire class (DIN 4102).
