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.

A photovoltaic assembly, comprising: four photovoltaic modules, each module comprising a set of frame members surrounding a photovoltaic laminate;an interlock securing the four photovoltaic modules together, the interlock comprising: (i) a joiner bar comprising at least one mounting portion dispo
1. A photovoltaic assembly, comprising: four photovoltaic modules, each module comprising a set of frame members surrounding a photovoltaic laminate;an interlock securing the four photovoltaic modules together, the interlock comprising: (i) a joiner bar comprising at least one mounting portion disposed between two ends of the joiner bar; and(ii) a pair of two-sided couplings, one attached to each end of the joiner bar, wherein each two-sided coupling supports two of the four photovoltaic modules, one on each side of the coupling, such that the joiner bar and couplings secure the four photovoltaic modules together at a four corner intersection of at least one of their respective frame members, wherein the pair of two-sided couplings comprises a pair of opposite facing tongue portions, each tongue portion being inserted into a side groove in one of the frame members of one of the four photovoltaic modules; anda height adjustable leveling foot movably connected to the at least one mounting portion of the joiner bar for supporting the joiner bar and the four photovoltaic modules above a support surface, a distance between the height adjustable leveling foot and the joiner bar being continuously adjustable within a range so as to adjust a height of the four photovoltaic modules above the support surface after the four photovoltaic modules are secured to the interlock. 2. The assembly of claim 1, wherein each tongue portion has a flat upper support surface. 3. The assembly of claim 1, wherein each tongue portion has an upwardly extending lip at its distal end. 4. The assembly of claim 1, wherein each two-sided coupling is configured to be slidably mounted onto the joiner bar such that each coupling can be moved in a direction parallel to a long axis of the joiner bar. 5. The assembly of claim 1, wherein each two-sided coupling has a hollow portion, and wherein a protrusion on the end of the joiner bar is received into the hollow portion of the coupling. 6. The assembly of claim 5, further comprising a set screw securing each of the two-sided couplings to the joiner bar. 7. The assembly of claim 6, wherein the protrusion on the end of the joiner bar is dimensioned such that the coupling can be rotated about an axis passing along the length of the joiner bar when the set screw is loosened. 8. The assembly according to claim 1, wherein the tongue portions are received into respective frame members of the four photovoltaic modules so that the joiner bar is positioned between the four photovoltaic modules at the four corner intersection of their respective frame members. 9. The assembly of claim 1, further comprising a rotatable stud for connecting the height adjustable leveling foot to the at least one mounting portion of the joiner bar, wherein rotation of the rotatable stud is configured to adjust the distance between the height adjustable leveling foot and the joiner bar. 10. The assembly of claim 9, wherein the at least one mounting portion of the joiner bar further comprises a threaded hole for engaging the rotatable stud, wherein the rotatable stud is accessible from above the joiner bar via the threaded hole to adjust the distance between the height adjustable leveling foot and the joiner bar after the four photovoltaic modules are secured together by the joiner bar and couplings. 11. An interlock for holding together four framed photovoltaic modules comprising: a joiner bar comprising at least one mounting portion disposed between two ends of the joiner bar; anda pair of two-sided couplings, one attached to each end of the joiner bar, each two-sided coupling having a pair of opposing photovoltaic module supports, each support dimensioned to support a frame of a photovoltaic module such that the joiner bar and couplings secure the four photovoltaic modules together at an intersection of their respective frame corners, wherein the pair of two-sided couplings comprises a pair of opposite facing tongue portions, each tongue portion configured to be inserted into a groove formed in the frame of one of the four photovoltaic modules; anda height adjustable leveling foot movably connected to the at least one mounting portion of the joiner bar for supporting the joiner bar and the four photovoltaic modules above a support surface, wherein a distance between the joiner bar and the height adjustable leveling foot is continuously adjustable within a range so as to adjust a height of the four photovoltaic modules above the support surface after the four photovoltaic modules are secured to the interlock. 12. The interlock according to claim 11, wherein each tongue portion is configured to be received into a frame of one of the four photovoltaic modules so that the joiner bar is centrally positioned between the four photovoltaic modules at the intersection of their respective frames. 13. The interlock according to claim 11, wherein each tongue portion has a flat upper support surface. 14. The interlock according to claim 11, wherein each tongue portion has an upwardly extending lip at its distal end. 15. The interlock according to claim 11, wherein each coupling is configured to be slidably mounted onto the joiner bar such that each coupling can be moved in a direction parallel to a long axis of the joiner bar. 16. The interlock according to claim 11, further comprising a rotatable stud for connecting the height adjustable leveling foot to the at least one mounting portion of the joiner bar, wherein rotation of the rotatable stud is configured to adjust the distance between the height adjustable leveling foot and the joiner bar. 17. The interlock according to claim 16, wherein the at least one mounting portion of the joiner bar further comprises a threaded hole for engaging the rotatable stud, wherein the rotatable stud is accessible from above the joiner bar via the threaded hole to adjust the distance between the height adjustable leveling foot and the joiner bar after the four photovoltaic modules are secured together by the joiner bar and couplings.
