摘要

A subassembly for inclusion in a three-dimensional structural frame of a solar collector module, the subassembly comprising: a plurality of frame members; and one or more hubs; wherein the plurality of frame members and the one or more hubs are interconnected; wherein each connection of one of the frame members to one of the hubs uses only a single respective fastener that permits relative rotation of the respective frame member and hub about the respective fastener; and wherein the subassembly is arranged in a compact configuration that is more compact than an expanded configuration in which the subassembly is to be used in the solar collector module.
