A stockpile of solar panels quickly becomes ineffectual without having a proper mounting system for the roof.
And as you might imagine, there is no one-size-fits-all for mounting systems. Nor do manufacturers stand in the same lineup with the same kind of products. And there are many, many choices.
Quick Mount PV recently announced US solar manufacturer SolarWorld was following an industry trend away from the use of long rails in mounting solar panels and shifting emphasis toward a rail-free racking system. The rationale? The latter’s cost savings in materials, labor, storage, and shipping.
Rail-free racking fixes solar panels directly to individual roof mounts, instead of standard long rails.
