Balance of system (BOS) refers to all of the various components of a photovoltaic (PV) system beyond the actual modules themselves. Of course, the mounting system (rails or racking, S-5 clamps and PVKIT®) are BOS components.
But, there are other BOS elements, such as wiring, switches, battery chargers, junction boxes, inverters, optimizers, other module-level power electronics (MLPEs), service walkways, conduit and wire chases.
At S-5!, we offer metal roof attachments for mounting these related solar PV components on both standing seam and exposed-fastened metal roofing.
All of our components carry a material/workmanship warranty for the life of the roof, so you are assured S-5! is “on the job” for the life of the solar array!
