Building integrated solar array support structure device, system, and method

A system comprising:

• at least one rail body comprising a bottom flange, a first upright member extending from a first end of the bottom flange, a second upright member extending from a second end of the bottom flange, an intermediate horizontal member extending between and linking the first and second upright,
• the at least one rail body further comprising a first bottom mounting rail extending downwards from the bottom flange, the first bottom mounting rail having two oppositely spaced upturned ends,
• a second bottom mounting rail extending downwards from the bottom flange, the second bottom mounting rail having two oppositely spaced upturned ends
• a bottom rail receiving slot arranged intermediate to the first and second bottom mounting rails, and
• the first and second upright members further including a vertical slot disposed at an intermediate position between the bottom flange and the corresponding first or second top flange;
• a first top flange disposed on a top end of the first upright, and a second top flange disposed on a top end of the second upright whereby a portion of the first upright, the intermediate horizontal member, and the second upright form a u-shaped channel, and
• wherein the intermediate horizontal member and the first upright member and second upright member cooperate to form an open-top, u-shaped channel having the intermediate horizontal member as a bottom surface for channeling a fluid, the bottom surface having a first length that is greater than a length of the first or second upright member determined from the intersection of the intermediate member to the respective first or second top flange;
• and wherein the intermediate horizontal member, a lower portion of the first upright member, the bottom flange, and a lower portion of the second upright member define a frame channel, the frame channel having a generally rectilinear profile when viewed end-on wherein the intermediate horizontal member defines a top wall of the frame channel and a length of the top wall is about the same as a length of a side wall of the frame channel;
• And, the rail body wherein the first and second top flanges each, respectively, further comprise:
• a T-shaped horizontal arm having a top surface, the T-shaped horizontal arm disposed at a distal end of the associated upright member and further having an inward extending shoulder terminating in downward pointing finger, the finger, inward extending shoulder and distal end of the associated upright member defining a first inward notch, and
• the T-shaped horizontal arm further having an outward extending shoulder having a downward extending arm and an inward extending finger, the downward extending arm, inward extending finger, outward extending shoulder, and distal end of the associated upright member defining a first outward L-shaped notch.
