Abstract
A photovoltaic system including a cell connection piece coupled to a plurality of photovoltaic cells and a terminal of a junction box. The cell connection piece includes an interconnect bus, a plurality of bus tabs unitarily formed with the interconnect bus, and a terminal bus coupled with the interconnect bus. The plurality of bus tabs extend from the interconnect bus. The terminal bus includes a nonlinear portion.
Claims16
A photovoltaic system, comprising:
- a plurality of photovoltaic cells within a photovoltaic module;
- a junction box coupled to the photovoltaic module, the junction box having a terminal;
- and
- a cell connection assembly comprising:
- a cell connection piece coupled to one or more of the plurality of photovoltaic cells, the cell connection piece comprising an interconnect bus and a plurality of bus tabs unitarily formed with the interconnect bus, wherein the plurality of bus tabs extend from only a single side of the interconnect bus;
- and
- a terminal bus bar coupled with the interconnect bus of the cell connection piece, the terminal bus bar coupled to the interconnect bus at a solder joint, the terminal bus bar including a first portion defining a non-orthogonal, curvilinear shape and a second portion defining either a tapered shape or a hole to facilitate coupling of the second portion of the terminal bus bar to the terminal of the junction box.
