Problems solved by technology

[0011] Disadvantage 1 of the prior art: When the bypass diode is turned on due to shadow occlusion, the currents of several parallel battery strings will all flow to the bypass lead through the electrode lead. According to Ohm's law, the heating value of the resistance is proportional to the square of the current, so the bypass The lead wire generates a lot of heat

Embodiment Construction

[0040] Below in conjunction with specific embodiment and accompanying drawing, the present invention will be further described:

[0041] The invention provides a pattern design solution that can be used for laminated photovoltaic modules, half-slice battery modules, 1 / 3 slice battery modules, and full-sheet battery modules, and can be used for double-sided laminated modules. The solar battery sheet can be a double-sided battery sheet that can absorb light to generate electricity on both the front and back sides.

[0042] A shingled solar photovoltaic module, which contains one or more solar cell strings, and each solar cell string is composed of two or more solar cell sheets. Adjacent sides of two adjacent solar battery sheets in the same solar battery string overlap with each other, and the overlapping width is 0.2 to 2.5 millimeters.

[0043] The overlapping area uses conductive material A, such as conductive glue, to form a conductive connection between the two battery she...

Abstract

The invention discloses an imbricate solar photovoltaic module and protection equipment thereof. The photovoltaic module comprises one or more solar cell strings and bypass leads, wherein the bypass leads are arranged along length directions of the cell strings and are arranged between adjacent solar cell strings or at an outer side of the solar cell string at an edge of the module, the solar cell strings are connected to form parallel connection by electrode leads and the bypass leads, and end parts of the bypass lead are connected with bypass convergence bars at end parts of the solar cell strings. A bypass current is shared by a plurality of bypass leads, and the heat generation quantity is reduced.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a shingled solar photovoltaic module and production equipment. Background technique [0002] A solar cell is a device that uses the photovoltaic effect to directly convert light energy into direct current. According to different photoelectric conversion materials, solar cells include monocrystalline silicon, polycrystalline silicon, amorphous silicon thin films, cadmium telluride thin films, copper indium gallium tin thin films, gallium arsenide, fuel sensitization, perovskite, stacked layers, etc. . The most common of these are crystalline silicon solar cells, including monocrystalline silicon solar cells and polycrystalline silicon solar cells. Solar cells are usually in the shape of a sheet. The side that absorbs light energy and converts it into electricity is called the light-absorbing side or front side, and the other side is called the back side. For some solar cell...
