Problems solved by technology

[0003] In the conventional technology, when resin is used for the front sheet and the back sheet, the solar battery cells move due to thermal expansion and contraction during lamination, resulting in positional misalignment
[0004] In addition, when resin is used for the front plate and the back plate, there is a problem that the conductors are wrinkled due to thermal expansion and contraction during lamination and use.

Embodiment approach 1

[0026] figure 1 It is a perspective view showing the appearance of the vehicle according to Embodiment 1 of the present invention. figure 2 It is a plan view showing the appearance of the solar battery module included in the vehicle according to Embodiment 1 of the present invention, and is viewed from figure 1 The figure viewed in the direction of arrow II. image 3 is in figure 2 It is a top view of the solar cell module in which the first cover is removed and the internal structure is enlarged. In addition, for the sake of simplification, only some solar battery cells of the solar battery module are described. Figure 4 It is a top view shown for explaining a positioning structure. Figure 5 is along Figure 4 The cross-sectional view of the V-V line in.

[0027] Such as Figure 1 to Figure 5 As shown, vehicle 100 according to Embodiment 1 of the present invention is an automobile, and includes: a solar cell module 110 constituting a roof; and a roof side member 12...

Embodiment approach 2

[0065] Figure 8 It is a plan view of the tab wire according to Embodiment 2 of the present invention. In the splice cord 230 according to Embodiment 2, another pedestal 233 is provided between the two pedestals 231 , and the pedestal 233 is not provided with a through hole, but only a connection seat is provided. Furthermore, the expansion-contraction part 232 which connects the pedestals 231 and 233 is comprised by four wave-shaped wiring 232a. The serial connectors 320 and 330 can also be configured in the same way.

[0066] According to the relationship of surrounding conditions, it can be deformed into various deformations such as a shape that emphasizes expansion and contraction, and a shape that emphasizes positioning. For example, if it is a shape that emphasizes expansion and contraction, the waveform wiring 232a can be easily expanded and contracted by making the wavelength of the waveform wiring 232a shorter or increasing the wave height (amplitude). If it is a s...

Abstract

The solar battery module of the present invention includes: at least one solar battery unit disposed between the first cover and the second cover; a sealing member embedded between the first cover and the second cover to join them to each other; sealing the solar battery unit; and a terminal wire as a conductor, which is electrically connected to the solar battery unit and surrounded by a sealing member between the first cover and the second cover, the terminal wire has: a plurality of pedestals; and a plurality of pedestals connected The telescopic part that can expand and contract along the longitudinal direction is provided with through-holes and connecting seats on a plurality of pedestals, and the connecting seats are electrically connected to the solar cells, and at least one of the first cover and the second cover has a function for positioning the terminal wires. The boss of the positioning part.

Description

technical field [0001] The present invention relates to a solar cell module and a conductor, and more specifically, to a solar cell module mounted on a vehicle and a conductor used for the solar cell module. Background technique [0002] Japanese Unexamined Patent Publication No. 2015-223065 discloses a structure in which adjacent solar cell strings are electrically connected in series by wiring using bus bar members. [0003] In the conventional technology, when resin is used for the front plate and the back plate, the solar battery cells move due to thermal expansion and contraction during lamination, and positional displacement occurs. [0004] In addition, when resin is used for the front plate and the back plate, there is a problem that conductors are wrinkled due to thermal expansion and contraction during lamination and use. Contents of the invention [0005] Therefore, the present invention was made to solve the above-mentioned problems, and an object of the prese...
