Flat roof solar racking system

A flat roof solar racking system configured for receiving at least one solar panel having an electrically conductive frame, said racking system comprising:

• (a) at least two substantially parallelly disposed panel support structures, wherein each panel support structure comprises:
• a first end, a second end, a top member having a substantially rectilinear first channel section connected to a substantially rectilinear second channel section and two ends, and a bottom member having a channel section and two ends, wherein said first and second channel sections are disposed in a plane but at an angle from one another and each end of said bottom member is fixedly connected to an end of said top member such that said top member is configured to make a first tilt angle at said first end with said bottom member and a second tilt angle at said second end with said bottom member;
• and
• (b) at least two spacer bars, wherein each spacer bar has two ends, each end electrically conductive with one of said at least two top members and each spacer bar is configured to connect said at least two top members;
• and
• (c) at least two retaining and grounding clips pairs, wherein each retaining and grounding clips pair is configured to secure a frame of said plurality of solar panels and be electrically common with said frame of said at least one solar panel and each grounding clip of said at least two retaining and grounding clips pairs comprises:
• (i) a planar body disposed in a plane;
• (ii) a pair of opposingly disposed first banks of teeth, each first bank of teeth is disposed in a plane and extending downwardly and outwardly from said planar body at a first angle with respect to said planar body;
• and
• (iii) a pair of opposingly disposed second banks of teeth, each second bank of teeth comprises a rotatable plate disposed in a plane and at a second angle with respect to said planar body and extending downwardly and outwardly from said planar body and terminating in a plurality of second teeth disposed upwardly in a plane and at a third angle with respect to said rotatable plate,
• wherein said grounding clip is interposed between said at least one solar panel and a top member of said at least two panel support structures such that each of said pair of first banks of teeth faces said top member of said at least two panel support structures and when a force is applied substantially perpendicularly to said plane of said planar body, at least one of said pair of second banks of teeth is adapted to rotate outwardly from said planar body and cause electrical grounding with said at least one solar panel.
