COST EFFECTIVE, ELONGATE MEMBER MOUNTINGS SYSTEM FOR PHOTOVOLTAIC DEVICES

摘要

Methods and devices are provided for improved rooftop solar module mounting assemblies. In one embodiment, an assembly is provided for mounting a plurality of photovoltaic devices over a roof surface. The assembly comprises of a plurality of elongate metal rods, wherein the elongate metal rods are connected together to define a support grid; a plurality of non-roof penetrating grid supports configured to elevate the support grid above the roof surface; and a plurality of grid-to-roof anchors that secure the entire support grid over the roof surface, wherein the number of grid-to-roof anchors is less than about 1/4 of the number of non-roof penetrating grid supports to minimize the number of locations where water may enter the roof surface.
