Description

[Detailed explanation of the idea] This invention relates to a solar cell module device.

Conventional solar cell modules are fixedly installed on a stand or inside a specific device and used only for a specific purpose, and the size of the module is also limited to 6V and 12V, which can cause battery life. It was adapted to electric power and was mainly used for industrial purposes.

The purpose of this invention is to have versatility for home use or school teaching materials, just like the dry batteries that are currently widely used, and to form one module based on an electromotive force of, for example, 1.6V, so that it can be easily used as desired. An object of the present invention is to provide a novel small-sized solar cell module device that is equipped with mechanical and electrical connection means that can perform series-parallel connection and form a single panel.

In the solar cell module device of this invention, a solar cell is pasted on a substrate having an overall parallelogram shape, and fixing means such as screw holes are provided at predetermined positions near each end of two opposing sides of the substrate. At the same time, these fixing means are electrically connected on each side by separate conductors, one electrode of the solar cell is connected to one of the conductors, and the other electrode of the solar cell is connected to the conductor. connecting means B that electrically and mechanically connects the solar cell unit A connected to the other of the solar cell unit A and the fixing means located near the corner of the substrate when the substrates are arranged in a row and column; The present invention is characterized in that the solar cell electromotive force on the substrate can be arbitrarily connected in series and parallel by a combination of the following.

Here, the term "parallelogram as a whole" includes not only right-angled quadrilaterals and parallelograms, but also those having some unevenness around the periphery. Further, the vicinity of both ends or corners of the opposite side preferably means both ends or corners of the opposite side, but in practice it is also possible to extend toward the center to a range that does not short-circuit with adjacent connecting members. Furthermore, as the fixing method of the present invention, in addition to the above-mentioned screw tightening, snap fixing, press-fitting, etc. may be used.

FIG. 1 shows one solar cell unit of the present invention. The solar cell 1 is pasted on a substrate 3 to constitute a module consisting of a plurality of cells connected in series and parallel, and its positive and negative electrodes are led out on both the upper and lower sides. The frame 2 on the outer periphery of the solar cell 1 has notches 5...5 formed at the four corners, and terminal plates 4A and 4B with screw holes are buried beneath them, and through holes are provided so that they can be fixed with screws. It is formed. The terminal plates 4B, 4B at both ends of the right side of the solar cell 1 are electrically connected to each other by lead wires 6, and the terminal plates 4A at both ends of the left side are similarly electrically connected to each other by lead wires. There is. The positive and negative electrodes of the solar cell 1 are electrically connected to either of these left and right lead wires.

FIG. 2 shows another embodiment of the solar cell unit of the present invention. The difference between this embodiment and the one in FIG. 1 is that metal plates 8A and 8B are provided along two opposing sides of the solar cell 1, and
By providing screw holes at both ends of 8B, the means to be fixed such as the screw holes of the present invention and the means for electrically connecting them are implemented using one metal plate. The negative electrode 7A of the solar cell 1 is connected to one metal plate 8A, and the positive electrode 7B of the solar cell 1 is connected to the other metal plate 8B. According to this embodiment, the rigidity of the device can be increased compared to the connection using the lead wire 6 as shown in FIG.

FIG. 3 shows a front view of a device in which four unit devices 3A, 3B, 3C and 3D shown in FIG. 2 are connected in series and parallel to each other. The devices 3A and 3C are electrically connected in series with the negative side of the device 3A and the positive side of the device 3C connected and fixed by connecting members 31A and 32. Note that only the electrode plates 8A and 8B in FIG. 2 and the negative electrode 7A and positive electrode 7B of the solar cell 1 are illustrated for the device 3A. The positive terminals of the devices 3A and 3B are connected to the connecting member 31B.
In addition, the negative electrode terminals are fixed by the connecting member 32 and connected in parallel. Furthermore, if the device 3D is connected to the devices 3A, 3B, and 3C by the connecting members 32, 31D, and 31C, the whole will be connected in series and parallel, and similarly, by combining and connecting several devices, an arbitrary connection can be made. You can get a power supply device.

According to the present invention, anyone can easily assemble a power supply with any voltage and current capacity depending on the purpose, so in addition to being able to drive various household electrical appliances with AC adapter terminals using solar energy, It can be widely used as an alternative to dry batteries for home use and school teaching materials.
