NOVELTY - The array (80) has a rail part comprising a first end that is located near a first gap between a first photovoltaic (PV) module (100) and a second PV module, and a second end that is located near a second gap between second and third PV modules. A first attachment bracket is located near the first end. A second attachment bracket is located near the second end. The second PV module is coplanar with and located between the first and third PV modules. The rail part is connected to the three PV modules and attached to a support structure (81) by the attachment brackets.    USE - Photovoltaic array for use on support structure such as slanted roof of a residential dwelling. Can also be used in flat roof, ground-mounted structure and vertical support structure i.e. pipe.    ADVANTAGE - The array simplifies the hardware and/or installation procedure required to mount PV modules on the support structure that requires discrete attachment points such as tile roof or ground mount structure. The array reduce or eliminate the need for long mounting rails beneath module arrays, thus reducing problems associated with warehousing, shipping and maneuvering long rails onto a roof. The array increases layout flexibility and simplifies installations on complicated roofs that have numerous smaller roof surfaces and/or numerous obstructions. The array ensures cost-effective mounting in landscape orientation and reduces total part count and total number of fasteners required. The array improves speed of installation and overall reliability of a PV array grounding system. The array provides greater integration with required equipment in the overall PV system such as electrical junction and combiner boxes, wire management devices. The array reduces total length of spanner bar and/or rail material due to optimization of structural support system. The array reduces total number of attachment points and ensures faster PV array system installations due to ability of a single installer to place and mount PV modules on support structure. The array ensures easy on-site changes to array layout when an actual rooftop does not accurately match the one used for a planned PV array system design.
