Description

  The present invention relates to a photovoltaic power generator, and in particular, a photovoltaic power generator such as a plurality of photovoltaic panels and photovoltaic power generator films can be folded between adjacent photovoltaic power generators. The present invention relates to a simple solar power generation device.

  Up to now, many solar power generation devices have been installed on the roof or roof of a structure such as a house, a building or a factory, or on a large site, with the establishment of a national power purchase system. A large number of photovoltaic power generators installed on such structures and sites support a photovoltaic power generator (photovoltaic power generation panel, etc.) in which a module consisting of multiple cells is arranged in a predetermined area while being tilted by a gantry. Most are done. On the other hand, some of the above-mentioned photovoltaic power generation devices have been used as a power source for calculators in recent years, or recently used as batteries for charging home electric appliances such as mobile phones.

  By the way, in the above-described solar power generation device installed on the structure or site, the solar power generation device is fixed to the structure or the like and is not portable. The power generator is small in size and therefore suitable for carrying, but the power obtained is small. In other words, it can be carried in places where there is no environment where commercial power can be obtained, or where power facilities have become unusable due to natural disasters such as an earthquake, and the required power generation can be secured. There is a demand for a simple solar power generation device.

  In view of the above, various types of solar power generation devices having the above-described functions have been proposed in the following. For example, a rigid panel with a photovoltaic film fixed to the upper surface is connected to each other in a specific direction by a hinge, and at a position where each hinge is fixed, a foldable structure is formed by repeating mountain folds and valley folds. In the folded state, a photovoltaic film is vertically layered, and in the unfolded state, the front faces of the plurality of photovoltaic films are horizontal (see Patent Document 1). I have. In addition, a plurality of photovoltaic panels are fixed on the upper surface of the flexible substrate, and the flexible substrate is folded between the plurality of photovoltaic panels and the photovoltaic panel. What has been made possible (Patent Document 2) has been proposed.

JP 2012-134462 A Japanese Utility Model Registration No. 3177813

  By the way, in each of the photovoltaic power generation devices disclosed in Patent Documents 1 and 2, each photovoltaic power generation body such as a photovoltaic power generation film and a photovoltaic power generation panel has a positive The terminals on the negative side and the terminals on the negative side are electrically connected by wiring, respectively, and are connected to a positive side cable and a negative side cable for external output, respectively. The positive cable and the negative cable are connected to electronic devices such as a storage battery and an inverter (power conditioner).

  Therefore, in the photovoltaic power generation devices disclosed in Patent Documents 1 and 2 described above, the length of the wiring connecting each of the photovoltaic power generators arranged side by side in a specific direction is extremely long. Not only the resistance is increased, but also as the number of photovoltaic power generators is increased, the folding operation is also increased, and there is a high risk that the wiring is disconnected in the middle.

  On the other hand, the amount of power generation desired by the user differs depending on the purpose of use, time of use, or place of use of the solar power generation device. In other words, when a large amount of power generation is desired, a solar power generator having a large area should be used, but when the area of each solar power generator is predetermined as a predetermined area. However, if a relatively large number of photovoltaic generators are to be used as components, a relatively small number of photovoltaic This is sufficient, and the number of photovoltaic power generators often differs from time to time. When a large number of photovoltaic power generators are used as components, the weight of the entire photovoltaic power generator increases, whereas when the number is small, the weight of the entire photovoltaic power generator increases. Decreases relatively.

  Therefore, the present invention has been proposed in order to solve the above-mentioned problems of the conventional solar power generation device, and not only is it foldable and excellent in portability, but also reduces the length of wiring. Not only can reduce the risk of disconnection of the wiring in the middle of the wiring, but also reduce the risk of individual solar power generators depending on the purpose and time of use of the user. It is an object of the present invention to provide a novel solar power generation device whose number can be appropriately changed.

  The present invention has been proposed in order to solve the above-mentioned problems, and a first invention (the invention according to claim 1) includes a plurality of base materials formed in a square shape, and a plurality of base materials. A relay substrate fixed to the front or back surface of a specific substrate that is one of the above, and a photovoltaic power generator disposed on another substrate other than the specific substrate, comprising: The other substrate on which the power generator is disposed may be a cloth or resin sheet fixed to the other substrate in the vertical direction and / or the left-right direction in plan view of the specific substrate to which the relay substrate is fixed. And the other foldable sheet body such as a cloth or resin sheet fixed to the specific base material is connected to the specific base material via a connecting means. Connected to the specific substrate so that the other substrate can be removed from the In each of the other base material, a minus cable and a plus cable on the power generator side whose base end is connected to the solar power generator are provided in a pair, and the specific base material is The base end is provided in a state in which a plurality of pairs of a minus side cable and a plus side cable on the relay board side connected to the relay board are provided in pairs, and the minus side cable on the power generator side and the minus cable on the relay board side are provided.

In other words, the specific substrate to which the relay substrate is fixed is present at a position sandwiched by a plurality of other substrates on which the photovoltaic power generators are arranged. Therefore, in the photovoltaic power generator according to the first invention, the sum of the lengths of the cables connecting the individual photovoltaic power generators and the relay board is different from that of the conventional photovoltaic power generator. This is shorter than the sum of the cable lengths when the bodies are arranged side by side in one direction. As a result, not only the electric resistance can be largely suppressed, but also the danger of disconnection of the cable or the like due to repeated folding operations described later can be remarkably improved.

  Further, in the first invention, the specific substrate and the other substrate are one foldable sheet body such as a cloth or a resin sheet fixed to the other substrate, and The other foldable sheet body such as a cloth or a resin sheet fixed to a specific base material is connected so that another base material can be detached from the specific base material via a connecting means. Therefore, each of the other substrates can be folded on the specific substrate or under the specific substrate, and the other substrates can be removed from the specific substrate. . Therefore, according to the photovoltaic power generator according to the first invention, the number of individual photovoltaic power generators can be appropriately changed according to the purpose of use, the usage time, and the like of the user. In addition, the specific base material and the other base material are engaged with each other by the slider operation of the slider, and a large number of elements fixed to one and the other fastener tapes having flexibility fixed to the respective base materials are engaged with each other.

It may be configured as In addition, this solar power generator is of a type (single-crystal silicon solar cell, crystalline silicon solar cell) using an individual single-crystal or polycrystalline silicon substrate, or a thin-film on a glass or metal substrate. An amorphous silicon solar cell formed of amorphous silicon described above, or a compound semiconductor solar cell using a plurality of elements as main raw materials (single-crystal compound semiconductor solar cell, polycrystalline compound semiconductor solar cell) may be used. In addition, the number of photovoltaic generators that make up a single group of photovoltaic generators (as a whole) formed in a square shape depends on the size of individual Depending on the relationship with the space on the base material to be made, for example, those arranged side by side so that the long sides of the photovoltaic film as two photovoltaic bodies formed in a rectangular shape are parallel to each other It may be.

  The connecting means constituting the present invention may be any means capable of detachably connecting the one sheet member and the other sheet member to each other. For example, one hook half may be connected to the one sheet member. The body may be fixed, the other hook half may be fixed to the other sheet body, and the one hook half and the other hook half may be connected to each other. In addition, one fastener tape is fixed to the one sheet body, the other fastener tape is fixed to the other sheet body, and a number of elements fixed to each of the one and other fastener tapes are operated by a slider operation.
