Embodiment 1
[0029] Embodiment 1, see Fig. 1-Fig. 4.
[0030] This embodiment provides a photovoltaic module with built-in diodes, such as Figure 1a-Figure 1d with figure 2 As shown, the photovoltaic module includes a front glass 1 , a front / rear encapsulation material layer 2 , battery strings 3 , bus bars 5 and a back plate or back glass 4 . A junction box 6 is arranged on the back plate or back glass 4 , and cables 7 and positive and negative terminals are connected to the junction box 6 . Such as image 3 As shown, a section of bus bar 5 is pre-welded on the positive and negative poles of the diode 8, and a longer bus bar is pre-welded if one of the poles needs to be connected to the wire box. When the components are stacked, the diode 8 with the bus bar 5 is connected according to the polarity between the two battery strings that need to be bypassed. One end of the longer bus bar 5 is pre-welded, and this part of the bus bar that grows is folded and led out of the assembly. The...
