A portable, retractable, solar racking system comprises a modular set of solar panel frames, each solar panel frame comprising a solar panel, a plurality of arms, and a plurality of struts, the arms and the struts forming a structure to which the solar panel is secured, a pivoting connector assembly mechanically connecting one of the solar panel frames to another one of the solar panel frames to form a solar panel array having a longitudinal extent, the pivoting connector assembly of the solar panel frames configured to collapse the solar panel array along the longitudinal extent into a storage position and to expand the solar panel array along the longitudinal extent into an extended position in which each solar panel is tilted from vertical to an angle away therefrom, and the solar panel array comprising sets of wheels permitting the solar panel array to roll upon ground.
