Solar cell module

摘要

A solar cell module including a substrate and solar cells mounted on the substrate, the substrate including a base layer, a first insulation layer positioned over the base layer, a second insulation layer positioned over the first insulation layer and defining a surface, a first bus bar layer positioned between the first and second insulation layers, the first bus bar layer including at least one bus bar extending across the substrate, and a second bus bar layer positioned over the second insulation layer, the second bus bar layer including bus bars, wherein the solar cells are mounted on the surface and are electrically interconnected by the bus bars of the second bus bar layer.

1. An individual solar cell module comprising:
a substrate formed as a layered structure, the substrate including:
a base layer;a first insulation layer positioned over said base layer;a second insulation layer positioned over said first insulation layer;a first bus bar layer positioned between said first insulation layer and said second insulation layer, said first bus bar layer including at least one bus bar extending across said first insulation layer and beneath said second insulation layer, wherein said at least one bus bar is configured to electrically couple said individual solar cell module to adjacent individual solar cell modules; a second bus bar layer positioned over said second insulation layer and being insulated from said first bus bar layer by said second insulation layer, said second bus bar layer including a plurality of bus bars, wherein at least one bus bar of said plurality of bus bars of said second bus bar layer includes at least one tab projecting outward therefrom and said at least one tab has at least two electrical connection points arranged over a center line of said at least one tab, at least one electrical connection point of said at least two electrical connection points being disposed on a first side of said center line and at least another electrical connection point of said at least two electrical connection points disposed on an opposite side of said center line; and a plurality of solar cells mounted on said substrate and electrically interconnected to one another in series and in a serpentine pattern by said plurality of bus bars of said second bus bar layer, said second bus bar layer being electrically insulated from said first bus bar layer within said individual solar cell module by said second insulation layer, wherein said plurality of solar cells define at least one junction between rows of solar cells of said plurality of solar cells, said at least one junction being aligned with said center line of said at least one tab of said at least one bus bar of said plurality of bus bars of said second bus bar layer such that at least one damaged row of said plurality of solar cells and a corresponding at least one tab with said at least two connection points are configured to be cut and divided at said junction and said center line of said corresponding at least one tab, and at least one remaining electrical connection point of said at least two connection points of said corresponding at least one tab is configured to electrically connect to at least one connection point of at least one tab of a replacement of said damaged row of said plurality of solar cells.
