An electrically conductive mounting/grounding clip, for use with a photovoltaic assembly of the type having an electrically conductive frame, comprises an electrically conductive body. The body has a central portion and first and second spaced-apart arms extending generally perpendicular to the central portion. Each arm has an outer portion with each outer portion having an outer end. At least one frame surface-disrupting element is at each outer end. The central portion defines a plane with the frame surface-disrupting elements pointing towards the plane. In some examples each arm extends from the central portion at an acute angle to the plane.

The clip according to claim 1 wherein the frame surface-disrupting elements comprise frame-surface-penetrating teeth. 3. The clip according to claim 1 wherein the arms are generally T-shaped. 4. The clip according to claim 1 wherein the acute angle is 80-88��. 5. The clip according to claim 1 wherein the acute angle is about 83��. 6. The clip according to claim 1 further comprising a plurality of said frame surface-disrupting elements at each outer end. 7. The clip according to claim 6 wherein the frame surface-disrupting elements of each arm are oriented in a direction generally parallel to a line connecting the outer ends of said arm. 8. An electrically conductive mounting/grounding clip for use with photovoltaic (PV) assemblies of a type having electrically conductive frames separated by gaps, the clip comprising: an electrically conductive body comprising a central portion and first and second spaced-apart, generally T-shaped arms extending from the central portion; each arm extending from the central portion at an acute angle to the plane; each arm having an outer portion, each outer portion having first and second outer ends; a plurality of frame surface-disrupting elements at each outer end; the frame surface-disrupting elements of each arm being oriented in a direction generally parallel to a line connecting the outer ends of said arm; and the central portion defining a plane and the frame surface-disrupting elements pointing towards the plane. 9.
