The newly improved S-5-PV Kit by S-5! is a rail-free, metal roof solar panel installation assembly. The embossed S-5-Mounting Disk with a module guide makes module placement easier. The S-5-Mounting Disk features four under-disk hooks to help with wire management and has strategically placed holes for zip tie connections. The S-5-PV Grab now has broader ears, making installation easier and more precise. The mounting disk is universally directional, and the S-5-PV Stud is longer to accommodate solar panel frame thicknesses from 32 mm to 64 mm.
