An apparatus and system for quickly and easily assembling PV modules into a PV array in a sturdy and durable manner. In some embodiments, the PV modules may have a grooved frame where the groove is angled into the frame with respect to the planar surface of the modules. Various components may engage within the angled groove to assemble the PV modules into the PV array using what may be referred to as a pivot-fit connection between the components and angled groove. Other embodiments may operate with PV modules having frames without angled grooves as by use of wraparound brackets.
