Description

  The present invention relates to a simplified power supply device, and more particularly, to a simplified solar power supply device that generates power with a solar panel and supplies the generated electricity as a power source to other electrical devices.

  The simple power supply device is a power supply device that is small and light and suitable for use in general homes and can be easily assembled. It is also effective as an emergency power source in the event of a disaster such as an earthquake. For this reason, it is desirable that the simplified power supply device can be used without any trouble even in the situation where it is difficult to procure fuel for power generation. Furthermore, it is desirable that the simplified power supply device is designed in consideration of environmental problems such as air pollution and noise caused by exhaust gas at all uses including disasters. In this regard, a simple solar power supply device that uses power obtained by solar power generation as a power source uses sunlight as an energy source, so even if it is difficult to procure fuel for power generation, etc. It is excellent in that it can be used without hindrance and is environmentally friendly without generating exhaust gas or noise. Furthermore, the simple solar power supply device is excellent from the viewpoint of energy saving measures and global warming countermeasures that have been particularly interested in recent years. Furthermore, although the solar cell itself does not have a charging (power storage) function, it is fully anticipated that an emergency power supply will be required even at night or in the rain, so the simplified solar power supply device has a charging function. It is desirable to be added.

  As a simple solar power supply device, for example, Patent Document 1 includes a solar panel and a battery box for charging electric power generated by the solar panel, a hook hole is provided on the solar panel, and the solar panel A folding foot is provided on the panel so as to be rotatable, the solar panel is mounted on a wall or the like through the hook hole, and the lighting angle of the solar panel is maintained by the folding foot, A simple power supply system is disclosed in which cigarette lighter type socket terminals for power input / output are mounted on the solar panel and the battery box (see Patent Document 1).

JP-A-9-261981

  By the way, recently, the types and number of electronic devices and household electrical appliances are increasing in general households, but these devices may be used alone or in a plurality of devices at the same time. Therefore, even when a simple solar power supply is used as a power supply for these devices, it is desirable that the power supply be compatible with such various usage forms. In addition, when using the power supply as an emergency power source in the event of a disaster, in addition to using it at home, bring it into an evacuation center (or equip it to a gymnasium that is assumed to be an evacuation center in advance) It can also be used as a power source for multiple homes and the entire refugee. Therefore, it is desirable that the power supply apparatus be compatible with various usage patterns even in such a case.

  Also, when using the power charged in the battery of the power supply device at night or in rainy weather, the solar panel is unnecessary, so the battery (more precisely, the control box including the related control unit etc.) ) Can be used as a power supply, which is more desirable because the power supply apparatus can be used in a more space-saving environment.

  However, since the conventional simple solar power supply device is not configured to be able to use only the control box including the battery as a power source, it can be used in a space-saving environment. There was a limit. In addition, there has been no one that can be used by connecting a plurality of simplified solar power supply devices corresponding to the various usage forms as described above. In addition, since there was nothing that was configured so that only the control box can be removed and used as a power source, it is natural that multiple batteries included in the removed control box can be connected and used There was no such thing.

  In addition, when configured to connect and use a plurality of simplified solar power supply devices and a plurality of batteries removed from them, the volume of the member increases as compared with the case of a single unit. It is important to save space, but the conventional simple solar power supply did not assume this type of use in the first place, so the idea was to save more space than a single unit. There was no such thing, and such a simple solar power supply device did not exist.

  Therefore, the problem to be solved by the present invention is a simple solar power supply device with a charging function, which can be used by removing only a control box including a battery and using it as a power source. The object is to provide an apparatus which can be used. Accordingly, it is an object of the present invention to provide a simple solar power supply device that saves more space than a single unit.

  In order to solve the above-described problems, the first invention is a solar panel arranged at an inclination, a mounting table provided in a position hidden behind the inclined solar panel, a battery mounted on the mounting table, and a battery. Provided is a simple solar power supply device including a control circuit, which includes a control panel connected to a solar panel and a detachable power supply circuit. Further, the second invention is based on the first invention, and the control box is a simplified type having a series connection terminal for connecting a plurality of batteries as an integrated power source in series connection with other control boxes. Provide solar power supply. Further, the third invention is based on the first or second invention, and the control box has a parallel connection terminal for connecting a plurality of batteries as an integrated power source by connecting in parallel with another control box. A simplified solar power supply device is provided. The fourth invention is based on the invention described in any one of the first to third, and the solar panel can be connected in series with other solar panels to use a plurality of solar panels as an integrated solar panel. A simple solar power supply device having panel series connection terminals is provided. The fifth invention is based on any one of the first to fourth inventions, and the solar panel is connected in parallel with other solar panels so that a plurality of solar panels can be used as an integrated solar panel. Provided is a simple solar power supply device having a panel parallel connection terminal.

  According to the present invention, there is provided a simplified solar power supply device to which a charging function is added, in which only a control box including a battery can be removed and used as a power source, and a plurality of these can be connected and used. It becomes possible to do. In addition, it is possible to provide a simple solar power supply device that is more space-saving than a single unit.

  <Overview>

  The simplified solar power supply device according to the present embodiment is a simple solar power supply device including a solar panel, a mounting table, and a control box. The solar panel is inclined and the mounting table is hidden behind the solar panel. It is characterized in that it is provided at a position and that the control box is connected to the solar panel by a detachable power circuit. The former feature is for reducing the space of the apparatus, and the latter feature is for enabling the apparatus to be used according to various situations.

  <Configuration>

    (General)

  FIG. 1 is a diagram showing an example of the appearance of a simplified solar power supply device of the present invention. As shown in the figure, the simplified solar power supply device 0100 of the present invention includes a solar panel 0110, a mounting table 0120, and a control box 0130. It is desirable that the size of the simple solar power supply is such that it can be easily assembled and installed in a general household room or a veranda. As an example of such a suitable dimension, the surface (front side of the solar panel) viewed from the direction of arrow A in this figure is the front, the front width is about 640 mm, the side width (depth) is about 500 mm, and the height is about 1260 mm. Is mentioned.

    (solar panel)

  A “solar panel” is a member for performing solar power generation, and a plurality of cells (solar cells) are connected in series and parallel so that necessary voltages and currents can be obtained. The entire solar panel is protected by a frame made of, for example, resin, metal glass, or metal. There are generally silicon-based and compound-based cell types, but the cell type used in the solar panel of the present invention is not particularly limited. Therefore, the material of the solar panel is not particularly limited. As an example of suitable dimensions of the solar panel, when the simplified solar power supply device has a front width of about 640 mm, a side width (depth) of about 500 mm, and a height of about 1260 mm, the front width of about 640 mm, Examples include a side width (depth) of about 35 mm and a height of about 1235 mm.

  The feature of the “solar panel” of the present invention is that it is configured to be inclined. The purpose of the arrangement so as to be inclined is to save space in combination with the point that the mounting table is provided in a position hidden behind the solar panel.

  As a configuration for placing the solar panel at an inclination, for example, if this apparatus is provided with a stand leg for supporting the solar panel, and the solar panel is leaned on this and fixed with screws or the like, it is installed. Good. In the example shown in FIG. 1 as well, two stand legs 0140 made of a metal-like rod-like member having a substantially right triangle shape are provided above the mounting table 0120 of this apparatus, and a solar panel 0110 is leaned against the hypotenuse 0140a of the stand legs. An example of fixing with a screw (not shown in this figure) is shown.

  Alternatively, the solar panel may be simply placed on a stand leg or the like without being fixed to the apparatus. Such a configuration can be particularly suitable for connecting a plurality of solar panels as will be described later as another embodiment.

    (Mounting table)

  The “mounting table” 0120 is for mounting the control box. Here, “to place” typically means an operation of simply placing without being fixed with a screw or the like. The purpose of simply placing the control box in this way is to facilitate handling during installation and removal of the control box and further movement of the entire apparatus. Particularly, as will be described later as another embodiment, such a configuration is suitable when a plurality of control boxes are connected. However, as long as it does not violate the above purpose, it is fixed to such an extent that it can be easily installed and removed (for example, a groove provided on the bottom surface of the control box and a rail provided on the mounting table are engaged with each other). Etc.) are not excluded.

  The feature of the mounting table in the simplified solar power supply device of the present invention is that it is configured to be provided at a position hidden behind the solar panel. The purpose is to save space of the simple solar power supply device in combination with the above-described configuration in which the solar panel is inclined. Another object is to prevent deterioration of the device included in the control box by preventing the direct sunlight from being blocked by the solar panel and hitting the control box on the mounting table. Also, it is to prevent the deterioration of the device included in the control box by preventing rain from being blocked by the solar panel and hitting the control box on the mounting table. Furthermore, the above purpose of preventing rain from hitting the control box can be suitably realized by allowing the vinyl sheet or the like to be easily covered from above using a solar panel and stand legs in the rain. It is in.

  Next, the specific meaning of “the mounting table is provided at a position hidden behind the solar panel” will be described. Here, "the mounting table is provided at a position hidden behind the solar panel" means that in the present invention, all or a part of the mounting table is disposed at a position overlapping the lower side of the solar panel (in other words, When viewed in plan, all or part of the mounting table is hidden behind the solar panel and cannot be seen).

  FIG. 2 is a conceptual diagram for explaining the specific meaning that the mounting table is provided at a position hidden behind the solar panel. Among these, (a) shows an example of the state in which the mounting table is provided at a position hidden behind the solar panel. In this figure, the entire mounting table 0220 is accommodated between two broken lines that descend vertically from both the left and right ends of the solar panel 0210. Although not shown in the figure, the mounting table is perpendicular to both the left end and the right end of the solar panel when viewed from the front with the surface viewed from the direction of arrow A (the surface on which the cells of the solar panel are arranged) as the front. Everything fits in between the two lines that get off at. This means that “the entire mounting table is disposed at a position overlapping the lower side of the solar panel”, which is a typical case “the mounting table is provided at a position hidden behind the solar panel”. In this case, the control box 0230 mounted on the mounting table is also preferably mounted so that its plane area is smaller than the area of the mounting table and does not protrude at all from the mounting table. All will be placed in a position that overlaps the lower side of the solar panel.

  FIG. 2B also shows an example of a state where the mounting table is provided at a position hidden behind the solar panel. In this figure, a part of the mounting table 0220 is accommodated between two broken lines vertically descending from both the left end and the right end of the solar panel 0210. Although not shown in the drawings, when the front view is the front view as viewed from the direction of arrow A, the mounting table is entirely within the two lines descending vertically from both the left and right ends of the solar panel. ing. This is an example of the case where “a part of the mounting table is disposed at a position overlapping the lower side of the solar panel”, and this is also included in the case where “the mounting table is provided at a position hidden behind the solar panel”. As another example of such a case, for example, when viewed from the right side as shown in FIG. 2 (a), the mounting table is between two lines vertically descending from the left end and the right end of the solar panel. All are contained, but when viewed from the front view, the mounting table is only partially contained between the two lines descending vertically from the left and right ends of the solar panel, In the case of 2 (b), even when viewed from the front view, there are cases where the mounting table is only partially between the two lines descending vertically from the left and right ends of the solar panel. Can be mentioned.

  On the other hand, FIG.2 (c) shows an example of the state in which the mounting base is not provided in the position hidden behind a solar panel. In this figure, the mounting table 0220 is completely removed from between the two broken lines vertically descending from both the left and right ends of the solar panel 0210, and a part of the mounting table 0220 has not been accommodated. Regardless of what the relationship is, it is not in a state where “a part of the mounting table is disposed at a position overlapping the lower side of the solar panel”. As another example of such a case, for example, when viewed from the right side as shown in FIG. 2 (a), the mounting table is between two lines vertically descending from the left end and the right end of the solar panel. However, when viewed from the front, the mounting table is completely removed from the two lines descending vertically from both the left and right ends of the solar panel, or FIG. In such a case, there is a case where the mounting table is completely removed from between the two lines descending vertically from both the left and right ends of the solar panel when viewed from the front view.

  Thus, in the present invention, the reason why the mounting table is configured to be provided at a position hidden behind the solar panel is as follows. That is, when the solar panel is disposed at an inclination, a space occupied by the simplified solar power supply device is generated even if nothing is disposed below the solar panel. Therefore, if the mounting table is arranged on the lower side, it is possible to save the need to secure a new space for this purpose. Further, such a configuration is also desirable because it is not necessary to secure a new space for the control box placed on the placing table. From this point of view, when the entire mounting table is arranged at a position overlapping the lower side of the solar panel, there is no need to secure new space for the mounting table and the control box. It can be said that this is a suitable case. In addition, in light of the purpose of preventing direct sunlight from hitting the control box as described above and the purpose of preventing rain from hitting the control box when it rains, the entire mounting table (and therefore the control box) It is most preferable that all of the above are arranged at a position overlapping the lower side of the solar panel. Furthermore, with this arrangement, as is clear from FIG. 2A, the control box is completely covered by covering the vinyl sheet from the top to the bottom using the solar panel and the stand legs in the rain. Therefore, the purpose of preventing rain from hitting the control box can be realized easily and suitably.

    (Control box)

  Returning to FIG. 1, the “control box” 0130 is placed on the “mounting table” 0120, includes a battery and a charge control circuit, and is connected to the “solar panel” 0110 by a detachable power supply circuit. That is, the control box is a member made up of a casing (box) for housing the battery and the charge control circuit, and the battery and charge control circuit housed therein. There is no particular limitation on the material of the housing of the control box, but a resin is preferably used. The dimensions of the control box are preferably such that they do not protrude from the mounting table, and the specific dimensions are regulated by the relative relationship with the entire simplified solar power supply and the mounting table. In addition, as mentioned below, the control box may include members other than the battery and the charge control circuit.

  The purpose of storing the “battery” is to charge the electricity generated by the solar panel so that the power supply can be used even at night or in the rain. In this case, the number of batteries stored in the control box may be one or two or more. In addition, a battery control unit for controlling input from the solar panel to the battery and output from the battery may be housed in the control box.

  FIG. 3 is a conceptual diagram showing an example of a power supply circuit including a control box in the present embodiment. This figure shows an example in which the batteries to be stored are two batteries 0331 and 0332 connected in series. In the figure, a battery control unit 0333 housed in the control box is also shown. This figure is a conceptual diagram, and only the battery and the battery control unit are shown in the control box. However, the positional relationship of these batteries and the battery control unit within the housing (not shown) is roughly the same as the positional relationship shown in this figure. Become.

  As will be described later, the control box is connected to the solar panel by a detachable power circuit. In the case of this example, the output cord 0352 extending from the solar panel 0310 is connected to the battery control unit via a connector or the like. Is done. The two batteries are connected in series to the battery control unit. The electricity charged in the battery is converted into an alternating current by an inverter (not shown), and is configured to be connectable from the battery control unit to another electrical device or the like via an output outlet 0353. In the drawing, a fuse 0361 appears at the left end of the battery control unit, and a ground wire 0362 extends below the battery control unit.

  In addition, this apparatus is not restricted to what is AC-converted and connected to an electric equipment etc. like the above example, You may connect to an electric equipment etc. with a direct current | flow. As an example of the latter case, it may be used for charging a battery-powered electronic device, a mobile phone or an electric razor, etc., such as an electric device that takes power from a cigar socket. In addition, the control box may be provided with a switching device for switching between AC output and DC output according to the usage form of the electric device or the like, and the switching may be controlled by a computer.

  As described above, the control box is configured to be connected to the solar panel with a detachable power supply circuit, so it is possible to remove only the control box (including the battery) from the simplified solar power supply and use it as the power source. (The same applies to other embodiments).

  Next, the “charge control circuit” is a circuit for controlling the charging of the battery, and when the battery voltage reaches a predetermined voltage (for example, 28.8 V), the output of the solar panel is set in an open state (disconnected state), Thereafter, when the battery voltage drops to a predetermined voltage (for example, 26V), charging is started again, and thereafter, the same ON / OFF is repeated.

  In addition, it is desirable that an overdischarge control circuit is provided along with the charge control circuit. The overdischarge control circuit turns off the inverter to prevent overdischarge when the battery voltage drops to a predetermined voltage (for example, 22V), and the battery voltage is set to a predetermined voltage (for example, by natural recovery of the battery and charging from the solar panel). 24V), the inverter is operated again.

  The control box in the present invention is placed on the mounting table as described above. The purpose of this is to save space for the present apparatus by saving a new space for arranging the control box. The specific meaning is as described above together with the mounting table.

  The control box is connected to the solar panel with a detachable power circuit.

  FIG. 4 is a diagram showing an example of a state in which the control box is connected to the solar panel by a detachable power supply circuit, and is a view of the simplified solar power supply device 0400 as seen from the back side. In the example of this figure, the input cord 0451 is connected to the control box 0430, the output cord 0453 is connected to the solar panel 0410, the connector 0453 attached to the tip of the input cord, and the tip attached to the tip of the output cord. A state where the control box and the solar panel are connected to each other by the power supply circuit is realized by connecting the connectors 0454 having shapes that can be freely fitted to each other. Or, unlike the example in this figure, the connector attached to the tip of the cord connected to the control box may be connected to the connector attached to the back of the solar panel, and conversely to the solar panel A connector attached to the tip of the connected cord may be connected to a connector attached to the control box.

  The purpose of configuring the control box so as to be connected to the solar panel by a detachable power supply circuit is to allow only the control box including the battery to be detached from the solar panel and used. In addition, by allowing only the control box including the battery to be removed from the solar panel in this way, it is possible to save space when connecting and using a plurality of batteries.

  As described in the following embodiments, the simplified solar power supply device according to the present invention (1) makes it possible to use a plurality of batteries as an integrated power source by connecting a control box in series with another control box. (2) The control box has a parallel connection terminal for allowing a plurality of batteries to be used as an integrated power source by connecting the control box in parallel with another control box. May be. In addition, (3) the solar panel may have a panel series connection terminal for connecting a plurality of solar panels as an integral solar panel by connecting in series with other solar panels, or (4) The solar panel may have a panel parallel connection terminal for connecting a plurality of solar panels as an integral solar panel by connecting in parallel with other solar panels. Here, the structure concerning these (1)-(4) is not restricted to an alternative thing. That is, the simple solar power supply device according to the present invention may have any configuration among them.

  <Effect>

  According to the invention of the present embodiment, a simple solar power supply device to which a charging function is added can be used by removing only a battery (or a box for storing the battery) and using it as a power source. It is possible to provide an apparatus which can be used. In addition, it is possible to provide a simple solar power supply device that is more space-saving than a single unit.

  <Overview>

  The simple solar power supply device of this embodiment is basically the same as the simple solar power supply device of the first embodiment, but a control box can be connected in series with other control boxes and a plurality of batteries can be used as an integrated power source. It is characterized in that it has a series connection terminal.

  <Configuration>

    (General)

  Similar to the apparatus of the first embodiment, the simplified solar power supply apparatus of the present embodiment also includes a solar panel, a mounting table, and a control box. However, in the simplified solar power supply device of the present embodiment, the control box has a series connection terminal for connecting in series with another control box so that a plurality of batteries can be used as an integrated power source.

    (Control box: Series connection terminal)

  FIG. 5 is a conceptual diagram showing an example of a power supply circuit including a control box in the present embodiment. Also in this figure, like FIG. 3, only the battery and the battery control unit in the control box are shown. Among them, the batteries 0531 and 0532 and the battery control unit 0533 shown on the left are included in the (one) control box 0530, and the batteries 0534 and 0535 and the battery control unit 0539 shown on the right are included in the other control box 0538. It is what The battery control unit 0533 of the control box 0530 is provided with a series connection terminal 0536. This series connection terminal is for connecting in series with another control box so that a plurality of batteries can be used as an integral power source. In the example of this figure, a cord 0555 attached to the terminal is connected to another control box. The battery control unit 0539 of the control box 0538 is connected. For this reason, other control boxes are also provided with a serial connection terminal 0537 for connection to the control box via a cord. The direct current from the plurality of batteries by connecting the plurality of control boxes in series in this manner is converted into an alternating current by an inverter (not shown) included in the control box. For example, an outlet 0553 included in another control box is connected to the control box. Thus, power can be supplied to the electrical equipment 0570.

  FIG. 6 is a diagram showing an example of a power supply circuit including a control box in the present embodiment, and shows an actual flow of electricity between the control boxes. That is, in FIG. 5, since it is a conceptual diagram, it is drawn in a simplified manner, but actually the flow of electricity between the control boxes is as shown in FIG. 6 (note that the description of the battery is omitted).

  In FIG. 6, the current flows from the positive pole of the battery control unit included in the (one) control box to the negative pole of the battery control unit included in the other control box and from the battery included in the other control box. The flow proceeds from the positive pole of the control unit toward the negative pole of the battery control unit included in the (one) control box. Then, after AC conversion, for example, power can be supplied to the electrical equipment 0670 via an outlet 0653 included in another control box.

  In this embodiment, “a plurality of batteries” refers to batteries included in different control boxes. In the simplest example, one battery is included in the (one) control box, and one battery is included in the other control boxes. Is included. In the case of the example of FIG. 5, the number of batteries included in each control box is two. However, in such a case, two or more batteries included in one control box are “multiple batteries”. It is not considered (the same applies to the following examples).

  In this way, the purpose of the control box having a series connection terminal for connecting a plurality of batteries as an integrated power source in series connection with other control boxes is the electrical equipment, etc. described at the beginning. This is to make it possible to cope with various usage forms. Particularly, in this embodiment, since the control box is connected in series with another control box, the maximum output of the battery can be increased. Therefore, it is possible to cope with a usage pattern in which the power consumption is relatively large as in the case where a plurality of electric devices are used simultaneously.

  <Effect>

  The simplified solar power supply device of this embodiment makes it possible to cope with various usage forms such as electrical equipment, and in particular, the maximum output of the battery can be increased, so that the power consumption becomes relatively large. It can respond to such usage patterns.

  <Overview>

  The simplified solar power supply device of the present embodiment is basically the same as the simplified solar power supply device of the first or second embodiment, but a control box is connected in parallel with other control boxes and a plurality of batteries are used as an integrated power source. It is characterized in that it has a parallel connection terminal for enabling use.

  <Configuration>

    (General)

  Similar to the apparatus of the first embodiment, the simplified solar power supply apparatus of the present embodiment also includes a solar panel, a mounting table, and a control box. However, in the simplified solar power supply device of the present embodiment, the control box has a parallel connection terminal for connecting in parallel with another control box so that a plurality of batteries can be used as an integrated power source.

    (Control box: Parallel connection terminal)

  FIG. 7 is a conceptual diagram showing an example of a power supply circuit including a control box in the present embodiment. In the figure, the batteries 0731 and 0732 and the battery control unit 0733 shown on the upper side are included in the (one) control box 0730, and the batteries 0734 and 0735 and the battery control unit 0739 shown on the lower side are the other control boxes. 0738. The control box 0730 is provided with a parallel connection terminal 0736. The other control box 0738 is provided with a parallel connection terminal 0737. This parallel connection terminal is for connecting the control box in parallel with another control box so that a plurality of batteries can be used as an integrated power source. In the example of this figure, the cord attached to the terminal is Although not directly connected to other control boxes, in this embodiment, the control boxes are not directly connected via the connection terminals in this way. That is, in the present embodiment, “the control box has a parallel connection terminal for connecting a plurality of batteries as a single power source by connecting in parallel with another control box” means that “the control box has a parallel connection terminal. And the purpose of the parallel connection terminal is “to allow the control box to be connected in parallel to another control box so that a plurality of batteries can be used as an integrated power source”. Note that FIG. 7 is also a conceptual diagram, so it is simplified and the actual flow of electricity between the control boxes is omitted, but parallel to that shown in FIG. 6 for FIG. It becomes.

  In this way, the control box has a parallel connection terminal for connecting a plurality of batteries as a single power source by connecting them in parallel with other control boxes. This is to make it possible to cope with various usage forms. In particular, in this embodiment, since the control box is connected in parallel with other control boxes, the duration of the battery can be increased. Therefore, it is possible to cope with a usage pattern in which the usage time becomes relatively long as in the case of continuously using an electric device or the like for a long time.

    (Control box: Connection procedure between control boxes)

  When connecting a control box to another control box, it is desirable to be able to easily connect the control boxes and save as much space as possible.

  FIG. 8 is a diagram illustrating an example of a connection procedure between control boxes. As shown in this figure (a), the control box of this example (in this case, only the main body excluding the lid) 0830 has an upper end (portion covering the lid) from the outer wall of the control box, like a heavy box. A wall-shaped protrusion 0830a that is slightly smaller is formed. This protrusion may be formed, for example, by fitting an outer box and an inner box, or may be formed in such a shape from the beginning by integral molding. FIG. 8B shows an example of the connection procedure between the control boxes shown in FIG. 8A, in which another control box 0838 shown in the upper side is stacked on the (one) control box 0830 shown in the lower side. Connects the control boxes with each other. In this case, concave portions 0830b and 0838b having dimensions and shapes so that the control box protrusions 0830a and 0838a exactly fit together are formed on the bottom surface of each control box, just like a heavy box. Therefore, in the example of this figure, the other control box 0838 can be stacked on the control box 0830 by fitting the recesses 0838b of the other control box 0838 to the protrusions 0830a of the control box 0830. Contrary to the example of this figure, a recess (formed by making the upper end surface of the inner box a little lower than the upper end surface of the inner box) is provided on the upper end side of the control box body, and this is provided on the bottom side. You may make it provide the convex part which fits (for example, it is formed by making the bottom part into the base-like part which protruded slightly from the horizontal cross section of the whole control box to the lower side of the outer wall lower part).

  In this case, the cover of the control box may be placed only on the control box main body arranged at the top. The same procedure can be used when stacking three or more control boxes.

  According to such a connection procedure, the control boxes can be easily connected to each other, and space can be saved.

  The above connection procedure is common when the control box as in this embodiment has a parallel connection terminal and when the control box as in the previous embodiment has a series connection terminal. In this case, illustration is omitted in this drawing so that electrical connection between the control boxes can be performed more easily, but the connection terminals appear on the same side surface of each control box, for example. It is desirable to be arranged.

  FIG. 12 is a diagram illustrating an example of a connection procedure between solar panels. As shown to this figure (a), the solar panel 1210 of this example forms the three substantially hemispherical recessed part (dent) 1210a in the side surface. Although not shown in the figure, a convex portion (projection) having a size and a shape that fits the concave portion is formed on the opposite side surface of the solar panel. FIG.12 (b) is the figure which looked at the solar panel shown to (a) from the front side. This figure shows a state in which three concave portions 1210a are formed on the right side surface of the (one) solar panel 1210 and three convex portions 1210b are formed on the left side surface. Similarly, a state in which three concave portions 1215a are formed on the right side surface of another solar panel 1215 and three convex portions 1215b are formed on the left side surface is shown. Therefore, in the example of this figure, the other solar panel 1215 can be connected to the solar panel 1210 by fitting the convex portion 1215b of the other solar panel 1215 to the concave portion 1210a of the solar panel 1210. In addition, the shape of the recessed part and convex part of this figure is an example to the last, and if it is the shape which both fits mutually closely, other shapes may be sufficient (for example, a convex part is substantially cone shape, substantially cylindrical shape, etc. Can be considered). In this case, the solar panel may be connected to a solar panel attached to another simple solar power supply device while being attached to the simple solar power supply device 1200 (a plurality of simple solar power supply devices are arranged side by side in appearance. The solar panels may be connected to each other with at least one solar panel removed from the original simplified solar power supply. In the latter case, for example, the long side of the substantially rectangular solar panel is oriented to form the upper and lower sides (in a flat state, the solar panel of FIG. 12 is rotated 90 degrees so that it is horizontally long) May be stacked vertically on the hypotenuse of the stand leg of one simple solar power unit.

  Furthermore, in order to make these connections easier, the solar panel may be simply placed on the oblique side of the stand leg rather than being fixed to the stand leg with screws or the like. In this case, in order to facilitate mounting, for example, a protrusion for holding the solar panel may be provided near the lower end of the oblique side of the stand leg. FIG. 12A shows such a protrusion 1221 provided near the lower end of the hypotenuse 1240a of the stand leg 1240. FIG.
