Embodiment Construction

[0021] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] As shown in FIG. 3 and FIG. 4 , the present invention mainly provides a structural design solution of a solar battery panel. The structure of the PCB board of the solar cell panel of the present invention is as shown in Figure 3, is provided with at least one group of mounting position 210 of solar wafer on one side of PCB board 200, and it is used for automatically or manually mounting solar wafer, in each A plurality of staggered pads 211 are arranged on the group mounting position 200 for respectively connecting the positive and negative electrodes of the solar chip; two groups of electrode pads 240 are also arranged on the same surface of the PCB board 200 to connect with the solar chip. All the pads 211 connected to the positive and negative electrodes are respectively connected to two groups of electrode pads 240 through conduct...

Abstract

The invention discloses a solar panel and the production method, at least one group of mounting positions of a solar wafer are arranged on one surface of a PCB plate of the solar panel, a plurality of pads which are staggeredly distributed are arranged on each group of mounting positions to be respectively connected with a positive electrode and a negative electrode of the solar wafer; the solar wafer is mounted on each group of mounting positions, each solar wafer constitutes a single cell; two electrode pads are further arranged on the same surface of the PCB plate, all single cells which are composed of solar wafers are connected in series or in parallel by conducting strips and then are respectively connected with two groups of electrode pads, wherein, one group of the electrode pad is used as the positive electrode output of a power, and the other group of the electrode pad is used as the negative electrode output of the power. The invention completely overcomes the shortcoming that an existing solar panel must be welded manually and provides the structural design proposal of the PCB plate to be used in the production of high-efficient mass solar cell panels by adopting advanced SMT process in advance.

Description

technical field [0001] The invention relates to the technical field of solar cell panel design, in particular to a solar cell panel and a manufacturing method thereof. Background technique [0002] The solar panel is the core part of the solar power generation system, and it is also the most valuable part of the solar power generation system. Its function is to convert the sun's radiation capacity into electrical energy, or store it in the battery, or push the load to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system. [0003] At present, the positive and negative electrodes of commonly used solar wafers are respectively distributed on both sides of the battery wafer. For such a solar chip, manual welding must be used, and the two sides of the battery chip are welded with wires to lead out the positive and negative electrodes of the solar chip, and then the solar chip is manually pasted on the PCB and the leads are ...
