Description

Anti-bumper waterproof solar cell module

technical field

The invention belongs to the technical field of solar cell assembly equipment, and in particular relates to a buffer-resistant waterproof solar cell assembly.

Background technique

The solar cell module has a structure in which a plurality of solar cells are electrically connected in series and/or in parallel through a wiring material electrically connected to electrodes on the surface thereof. When manufacturing this solar cell module, conventionally, solder is used to connect the electrodes of the solar cell and the wiring material. Solder has excellent connection reliability such as electrical conductivity and adhesive strength, and is inexpensive and versatile, so it is widely used. Conventionally, in order to reduce the influence of heat during the connection of wiring materials, a method of connecting wiring without using solder has been studied. The wiring material is connected to the electrode of the solar cell by disposing a resin adhesive between the electrode of the solar cell and the wiring material, and heating while pressing the solar cell and the wiring material against each other. However, in order to reduce the cost and resources of the solar cell, it is required to reduce the thickness of the solar cell.

The unreasonable assembly of the existing solar cell components will affect the power generation efficiency of the solar cells. The use of mechanical parts in the fixing process has poor cushioning performance, and the service life of the solar cell components will be reduced during use. In addition, existing solar cell modules are poor in water resistance. Therefore, how to develop an anti-bumper and waterproof solar cell module has important practical significance.

Contents of the invention

Aiming at the technical problem of poor cushioning performance of solar cell components in the prior art, the purpose of the present invention is to provide a buffer-resistant and waterproof solar cell component.

The technical scheme that the present invention takes is:

Anti-buffer and waterproof solar cell module, including several solar panels. Bus bar electrodes are arranged on the sunny side of the solar panel. Adjacent bus bar electrodes are connected by a thin grid line, and each thin grid line is radial. Setting, the back of the bus bar electrode is provided with finger-shaped electrodes, and the area opposite to the finger-shaped electrodes is provided with an auxiliary electrode plate for covering a larger area than the area where the finger-shaped electrodes are arranged, and the side plate of the solar cell panel is fixed by an annular sealing ring , the annular sealing ring is set in an oblate shape, the middle part of the annular sealing ring is provided with a waterproof membrane, the other end of the waterproof membrane is extended and fixed on the auxiliary electrode plate through screws, and the four corners of the auxiliary electrode plate are fixed on the solar panel through shock pads On the back plate, diversion lines are arranged on the outer surface of the waterproof membrane.

Further, the radiation origins of the fine grid lines are all set at the ends of the bus bar electrodes.

Further, an annular protrusion made of hydrogenated nitrile rubber is provided around the annular sealing ring.

Further, the shock absorbing pad is set as a hollow square elastic rubber pad.

Further, the diversion lines of the waterproof membrane extend to the outside of the solar panel through the conical head at the end.

Further, the auxiliary electrode plate is fixed by conductive columns and bus bar electrodes.

The beneficial effects of the present invention are:

In the present invention, adjacent bus bar electrodes are connected by a radial thin grid line, so that while the bus bar electrodes play the role of main grid lines, the area of the bus bar electrodes can also be set larger to improve the power generation rate ;The synergistic auxiliary effect of the finger electrode and the auxiliary electrode plate makes the assembly of the solar cell module more reasonable. The influence of impact, strong buffer resistance, after the solar cell module is assembled, it forms a relatively closed environment, and the waterproof membrane with diversion lines has a good waterproof effect.
