Cable management systems and methods for photovoltaic systems and other cable-dependent systems

A cable management system, comprising:

• at least one cable-retaining spacer assembly, each cable-retaining spacer assembly including:
• a base body including first and second ends, first and second faces, and top and bottom sides, the base body including first and second engagement fingers extending from the first and second ends, respectively, thereof, the first and second engagement fingers each including an engagement protrusion, the base body defining a plurality of channels spaced-apart between the first and seconds ends of the base body and extending from the first face to the second face, each channel configured to receive a transmission cable therein;
• and
• a cover body including first and second ends, first and second faces, and a backspan, the first and second faces each defining alternating panels and cut-outs,
• wherein the cover body is configured for engagement with the base body whereby each channel of the plurality of channels aligns with one of the cut-outs to define a passage configured to circumferentially enclose each transmission cable;
• and
• first and second brackets configured for positioning at the first and second ends of the base body, each of the first and second brackets including at least one window and at least one engagement detent defined in an outwardly-facing surface thereof, wherein the first and second engagement fingers of the base body are configured to extend through the at least one window of the first and second brackets from an inwardly-facing surface thereof to the outwardly facing surface thereof to enable engagement of each engagement protrusion within a corresponding one of the engagement detents to thereby retain the base body suspended between the first and second brackets.
