Abstract: A frame assembly is provided for a solar module. The frame assembly includes a plurality of frame members that are structured to collectively support and hold a first solar panel. At least one of the plurality of frame members is structured to adjoin a frame member of a second solar module in forming a joining with the frame member of the second solar module over a length where the frame member of the first and second solar module adjoin.

Abstract: A rack assembly is provided for mounting solar modules over an underlying body. The rack assembly may include a plurality of rail structures that are arrangeable over the underlying body to form an overall perimeter for the rack assembly. One or more retention structures may be provided with the plurality of rail structures, where each retention structure is configured to support one or more solar modules at a given height above the underlying body. At least some of the plurality of rail structures are adapted to enable individual rail structures o be sealed over the underlying body so as to constrain air flow underneath the solar modules. Additionally, at least one of (i) one or more of the rail structures, or (ii) the one or more retention structures are adjustable so as to adapt the rack assembly to accommodate solar modules of varying forms or dimensions.

Abstract: A mounting system is provided for solar modules with a compressable retention structure for solar modules. The retention structure may interleave a upper and lower rail that provides a shelf or other support structure in order to hold a solar module or panel in an operative position. The upper and lower rails may be compressed towards one another in order to cause the support structure to retain the solar modules or panels.
