A multi-purpose photovoltaic module framing system is provided which combines and integrates the framing system with the photovoltaic electrical system. The user friendly framing system is easy to install and can be directly mounted to a roof surface without auxiliary brackets and beams. The economical framing system has aesthetically pleasing frames to mechanically hold and support photovoltaic modules. The multi-purpose frames desirably have integral electrical raceways which conceal and protect most electrical components and wires. The reliable frames are specially constructed and arranged to permit easy access to output wires and do not require junction boxes. Ground clips can be directly connected to the convenient framing system. |

DETAILED DESCRIPTION An improved photovoltaic module framing systems is provided which is user friendly, easy to install and assemble, and economical.
Advantageously, the reliable multi-purpose photovoltaic module framing system is aesthetically pleasing, conceals most electric components, and permits easy access to output wires.
Desirably, the special photovoltaic module framing system combines and integrates the module framing system with the photovoltaic electrical system.
Significantly, the improved photovoltaic module framing system does not require an electrical junction box or electrical conduits, nor does it require an auxiliary bracket, brace, or beam, as in bulky prior framing systems.
Furthermore, the improved framing system does not use inwardly facing flanges of the type used in prior framing systems.
The novel photovoltaic framing system comprises an electrical wire-enclosing assembly to support, enclose and conceal a substantial portion of electrical wires in the photovoltaic module.
Desirably, the electrical wire-enclosing assembly also comprises a frame positioned about the periphery of the photovoltaic module to mechanically hold the module.
Significantly, the frame has at least one rail which receives fasteners to directly mount the photovoltaic module on or to a roof, wall, rack, beam, or other structure.
Preferably, the frame has portions to space the photovoltaic module above a roof, so as to form a gap therebetween to channel rain and water, as well as to provide an air passageway to cool the module.
In the preferred form, the frame has at least one electrical raceway and has a ground clip to electrically ground the electrical wire-enclosing assembly.
The frame of the outboard module can have an outboard side rail which is covered by a removable outboard row closure.
The outboard side rail and the outboard row closure cooperate with each other to define an electrical raceway therebetween to enclose, conceal and protect plugs (plug connectors), wires and output interconnections
