Abstract

PURPOSE:To enable even three-dimensional arrangement, and to fit a module for a solar cell to a novel use by bringing the external form of the module to an equilateral triangle and previously connecting all of solar cell elements in the module in series when the elements are connected electrically by using an internal connecting wire, and sealed in an airtight manner and the module for the solar cell is manufactured. CONSTITUTION:A plurality of solar-cell elements 2 are arranged triangularly on a plane, all of them are connected electrically in series by using internal connecting wires 3, and the output terminals of the wires 3 are connected to terminals 4 and 4' mounted at the corner sections of a triangle. A transparent support material 5 consisting of glass, etc. is mounted on a beam irradiating surface, a resin 6 for an airtight sealing is applied on the back and cured, thus manufacturing an equilateral triangle type solar-cell module 1. Consequently, the module 1 is brought to an equilateral triangle, and these modules are joined by using flexible materials 7 and formed to a fold-able shape. Accordingly, the joined modules are expanded to a trigonal pyramid shape, a quadrangular pyramid shape or a hat shape in response to uses, a secondary battery can also be received in the inside, and the joined modules are fitted to novel uses.

Description

[Detailed description of the invention] The present invention relates to the external shape of a solar cell module.

In order to obtain the required power, the conventional solar cell module, which is the smallest unit of solar cells, is connected in series and parallel to the solar cell module, which is then connected flatly to a rectangular solar cell array. It was common to arrange them and set the fixed feet at the desired angle of elevation for 14 uses. In such conventional applications, square (
In particular, rectangular (rectangular) solar cell modules are suitable because they can minimize the installation area and are easy to install when arranging on a plane. However, Tai! # With the increasing use of solar cells as batteries become cheaper and lighter, conventional prismatic solar cell modules had problems such as being difficult to arrange three-dimensionally and requiring a large area for transportation. .

The present invention can eliminate such conventional drawbacks and provide a solar cell module that is easy to install and convenient to handle.

A feature of the present invention is that in a solar cell module formed by electrically connecting a solar cell element with an internal connection line and then hermetically sealing the solar cell module, the outer shape of the solar cell module is an equilateral triangle; A solar module in which all the solar cell elements in a battery module are connected in series is placed in a solar module using a pond module and this solar battery module.

The present invention will be explained in detail below with reference to the drawings. FIG. 1 and FIG. 2 show an example of the structure of a solar module according to the present invention. In FIGS. 1 and 2, an equilateral triangular solar cell module l includes an internal connection line 3 for connecting solar cell elements 2 in series, electrical output terminals 4, 4', a transparent support material,
For example, it is composed of glass 5 and side fat 6 for airtight sealing. In such an equilateral triangular solar cell module, the value obtained by dividing the solar cell element area by the total area of the module (i.e. module area efficiency) is about 0.7, which is higher than that of the conventional square type solar cell module.
Compared to the t=pond module, it is possible to obtain a structure that is not inferior in any way and is optimal for new applications as described below.

FIG. 3 shows an example in which an equilateral triangular solar cell module according to the present invention is used. In FIG. 3, numeral 1 indicates an equilateral triangular solar pond module, and five of these modules are combined to form a chevron shape. For example, the shape can be used as a "hat" and used as a sunshade, and at the same time, if used in conjunction with a small secondary battery, it can be used as a portable simple power source.Selecting the number of solar cells in the solar module It is possible to obtain the required voltage.Also, by connecting each equilateral triangular solar cell module in partial rows, even if there is uneven solar radiation in some parts, the solar cell modules receiving solar radiation can be In addition, by connecting each solar module with a material 7 that is easy to fold, it becomes foldable and convenient for transportation.

Further, FIG. 4 shows a second embodiment according to the present invention. Fourth
In the figure, reference numeral 1 denotes an equilateral triangular solar battery module, and one or two of them are used together with a display panel 8 to form a square pyramid (or triangular pyramid). By using a secondary battery in combination with the first embodiment and IIf1, it is possible to obtain a solar cell that is easy to install, for example, on a traffic sign.

Furthermore, FIG. 5 shows a third embodiment according to the present invention. Fifth
The figure shows a hexagonal solar cell sub-panel indicated by 1', which is made by arranging a plurality of equilateral triangular solar cells on a plane, similar to the conventional Taiyojima pond frame. It is also easy to arrange them.

As explained above, it will be clear that by using the equilateral triangular solar cell module according to the present invention, a solar cell that can be easily adapted to new applications can be obtained.
