Photovoltaic Fixing system for crystalline rigid photovoltaic modules panels on system a corrugated for roof multilayer consisting of Ondulit/Coverib extruded aluminum U-bolts, sheets spacer profiles in extruded aluminum, aluminum brackets for anchoring the module to the profile and anchoring system (M8 screw and steel guided slider).
The extruded aluminum U-bolts are at the same time an element for fixing the cover to the supporting structure and housing the spacer.
The spacer, placed parallel to the slope of the roof, in correspondence with a rib of the sheet, consists of an extruded aluminum profile characterized by two lateral grooves for fixing the profile to the jumper by means of a guided slider in steel threaded bolt M8 and by a groove upper for fixing photovoltaic modules by means of a steel slider with M8 threaded bolt. The system allows the fixing of the photovoltaic modules to the supporting structure through the corrugated sheet, without holes in the roof with the exception of holes for structural fixing. The system creates a layer of ventilation beyond the corrugated profile of about 6 cm.
