Racking system for installing solar panels
View Patent ↗A racking system is configured to install at least one photovoltaic panel on a rooftop. The racking system includes a plurality of rails. A splice bar is connected the plurality of rails and configured to mechanically strengthen the plurality of rails. A ground lug is attached to an extrusion of a side channel on each of the plurality of rails by sliding the ground lug through a rail opening. A ground wire is held in a serrated opening for safely grounding the racking system. A clamp is attached to a top channel of at least one rail such that the at least one rail and the at least one photovoltaic panel are operatively coupled to the clamp and such that the clamp is under pressure due to a spring but is able to freely rotate around a longitudinal axis.
1. A racking system, configured to install at least one photovoltaic panel on a rooftop, the racking system comprising:
first rail and a second rail, each rail further comprising a first extruded channel, a second extruded channel, a top channel, a first side channel, a second side channel;
a splice bar, connected to the first rail and the second rail and configured to mechanically strengthen each rail; the splice bar further comprising a central rectangular tube joined to a centrally located narrow portion;
a ground lug, further comprising:
a rail attachment portion having a rail attachment serrated portion that slides into the first extruded channel;
a rail bolt, joining the rail attachment portion into the first extruded channel;
a serrated opening; above the rail attachment portion; wherein a ground wire is electrically bonded to the serrated opening with a wire bolt;
an L-foot bracket, attached to the first side channel and an inverter;
a clamp, attached to the top channel of the first rail such that the first rail and the at least one photovoltaic panel are operatively coupled to the clamp.
2. The racking system of claim 1 , wherein first rail further comprises a rail end covered by a rail end cap.
3. The racking system of claim 2 , wherein the splice bar is connected to the first rail and the second rail using a plurality of Tek screws.
4. The racking system of claim 1 further comprising a clip bracket, inserted into the slot between the side channel and the top channel by aligning with the mid-clamp for holding wires running through the at least one photovoltaic panel, wherein the clip bracket is aligned with the mid-clamp in order to securely hold at least one clip bracket on opposite sides of the first rail and the second rail.
5. The racking system of claim 4 , wherein the clip bracket comprised a wire clip attached to a top exterior surface of the clip bracket.
6. The racking system of claim 5 , wherein the inverter is directly attached to the top channel of the first rail.
7. The racking system of claim 6 , wherein the L-foot bracket is attached to a non-penetrating mount and then attached to the inverter.
