Description

  The present invention relates to a photovoltaic power generation panel diagnostic apparatus for diagnosing the power generation state of a photovoltaic power generation panel. The present invention also relates to a sound insulating wall used as ancillary equipment for a traveling path on which a vehicle such as an automobile or a train travels, and particularly relates to a sound insulating wall including a sound insulating panel integrated with a solar power generation panel. The present invention further relates to a window glass for buildings or a window glass for vehicles integrated with a photovoltaic power generation panel.

  Noise barriers may be installed as ancillary equipment on traveling roads on which vehicles such as automobiles and trains run, especially on expressways and automobile roads. The sound insulation wall is installed along the side portion of the traveling path, and suppresses noise generated by traveling of the vehicle from reaching the vicinity. Such a sound insulation wall is constructed by stacking and holding a plurality of sound insulation panels between pillars installed at predetermined intervals along the end of the traveling path.

  In recent years, attempts have been made on solar power generation using sound insulation walls from the viewpoint of protecting the global environment through energy saving. For example, Patent Document 1 describes an invention in which a part of a sound insulation panel forming a sound insulation wall is cut out and a photovoltaic power generation panel is fitted in the cut out part. According to the description in Patent Document 1, the photovoltaic power generation panel is assumed to have transparency (see paragraph 0024). When one solar cell is attached, the transparency is maintained from the periphery of the solar cell, and when a plurality of solar cells are attached, the solar cells are arranged at intervals that do not impair the transparency. (See paragraph 0031).

  Patent Document 2 discloses a more sophisticated structure as a solar power generation panel having translucency. That is, Patent Document 2 discloses a photovoltaic power generation panel in which spherical solar cells connected between a pair of transparent plates are sealed.

  The amount of power generated by a solar power generation panel decreases due to aging or failure. In particular, a sudden drop in power generation due to a failure is a serious problem. For this reason, it is necessary to periodically diagnose the power generation state of the photovoltaic power generation panel in equipment or the like where the photovoltaic power generation panel is installed. In this case, if there are several or several tens of photovoltaic power generation panels, there is no complication even if the power generation state is diagnosed one by one. However, for example, when a solar power generation panel is installed in each of the sound insulation panels constituting the sound insulation wall of the expressway, a huge number of solar power generation panels are provided. Therefore, it is virtually impossible to diagnose the power generation state one by one. For this reason, we would like to be able to easily diagnose the power generation state of the photovoltaic power generation panel with some reasonable method.

  In particular, when the photovoltaic power generation panel is provided with translucency, fine wiring for connecting a plurality of solar cells exists in the photovoltaic power generation panel. For this reason, when the solar power generation panel which has translucency is used for the sound insulation wall exposed to the influence of vibration, there is a concern about a rapid decrease in the amount of power generation due to the failure of the solar power generation panel. Thus, when such a light-transmitting photovoltaic power generation panel is used as a sound insulation wall, the demand for the diagnosis is expected to increase further.

  FIG. 1 is a rear view showing a sound insulation wall. The sound insulation wall 101 is constructed by stacking and holding a plurality of sound insulation panels 103 between a plurality of support columns 102 installed at predetermined intervals along a traveling path (not shown) on which the vehicle travels. .

A photovoltaic power generation module 108 is configured by collecting a plurality of photovoltaic power generation panels 104 in a matrix arrangement in the vertical and horizontal directions. The photovoltaic power generation module 108 is divided into a plurality of systems 109 that are a set of photovoltaic power generation panels 104 arranged in a horizontal row. The photovoltaic power generation module 108 is a unit associated with one power conditioner 105, and the system 109 is a unit associated with one connection box 107.

  In one system 109, individual photovoltaic power generation panels 104 are connected in series. The connection box 107 connects the individual systems 109 to the power conditioner 105 in series.

  The photovoltaic power generation panel 104 and the connection box 107 are provided with a failure detection unit 201 and a failure detection unit 301 that form part of the diagnostic device A for the photovoltaic power generation panel 104, respectively.

  The failure detection unit 201 of the photovoltaic power generation panel 104 individually feeds power to the pair of LED lamps 202 from the two adjacent photovoltaic power generation panels 104. When the power supply amount is the same, the pair of LED lamps 202 is equivalent. A light emitting circuit 203 that emits light is included. The light emitting circuit 203 includes two circuits C1 and C2 that connect the input end and the output end of the photovoltaic power generation panel 104 and directly connect the resistor R and the LED lamp 202. In the light emitting circuit 203, the LED lamp 202 included in one circuit C <b> 1 is disposed in the own photovoltaic power generation panel 104, and the LED lamp 202 included in the other circuit C <b> 2 is disposed in the adjacent photovoltaic power generation panel 104. Such an arrangement of the LED lamps 202 will be described later.

  The failure detection unit 301 of the connection box 107 individually supplies power to the pair of LED lamps 302 from two adjacent systems 109 formed by a plurality of photovoltaic power generation panels. The light emitting circuit 303 that emits the LED lamp 302 equivalently emits light equivalently. The light emitting circuit 303 connects the input end and the output end of each system 109 formed by a plurality of photovoltaic power generation panels, and directly connects the resistor R and the LED lamp 302.

  FIG. 3 is a block diagram showing a system configuration of the solar power generation system 11. The solar power generation system 11 includes a plurality of sets of solar power generation modules 108 each of which includes one power conditioner 105 and a connection box 107, and these solar power generation modules 108 are directly connected to the distribution board 110. The distribution board 110 drives the load 111 with a part of the power supplied from the plurality of solar power generation modules 108 and provides the other part to the commercial power system 112.

  The unit of such a distribution board 110 is a small system, and this small system generates about 10 kW of electric power to drive the load 111 and provide electric power to the commercial power system 112.

  FIG. 4 is a block diagram showing in detail the portion of the power conditioner 105.

In addition, a voltage / failure display unit 105b is provided in one power conditioner 105 constituting the photovoltaic power generation system 11 which is a small system. The failure display unit 105b takes in the voltage detected by the voltage detection circuit 105a in each power conditioner 105, and displays the voltage state and the presence / absence of a failure in each photovoltaic module 108.

  FIG. 5 is a block diagram illustrating another example of the failure detection unit 201 of the photovoltaic power generation panel 104. As described above, the failure detection unit 201 illustrated in FIG. 2 individually supplies power to the pair of LED lamps 202 from the two adjacent photovoltaic power generation panels 104, and when the power supply amount is the same, the pair of LED lights The circuit structure is mainly composed of a light emitting circuit 203 that emits light equivalently to 202. That is, although the details will be described later, the light emission states of the pair of LED lamps 202 associated with the two adjacent photovoltaic panels 104 are compared, and a malfunction of one photovoltaic panel 104 is diagnosed by human judgment. This is the configuration. For convenience of explanation, such a failure detection unit 201 illustrated in FIG. 2 is referred to as a failure detection unit 201 of the first example.

  In contrast, when a failure occurs in one of the photovoltaic power generation panels 104, the failure detection unit 201 illustrated in FIG. 5 uses the LED lamp 202 associated with the photovoltaic power generation panel 104 in which the failure has occurred. The failure detection circuit 204 to be lit is mainly configured. For convenience of explanation, the failure detection unit 201 of this example illustrated in FIG. 5 is referred to as a failure detection unit 201 of the second example.

  FIG. 6 is a circuit diagram showing details of the failure detection circuit 204 of the photovoltaic power generation panel 104. The failure detection circuit 204 of this example is connected in parallel to a pair of LED lamps 202 that are connected in parallel with the rectifying direction reversed with respect to the power supply line PSL of two adjacent photovoltaic power generation panels 104. . A Zener diode TD is interposed on the anode side of each of the pair of LED lamps 202.

  Therefore, when the power generation amounts of the two photovoltaic power generation panels 104 are equal, no current flows through each of the pair of LED lamps 202, and therefore there is a potential difference between the input side and the output side of each LED lamp 202. It does not occur and the pair of LED lights 202 are not lit. On the other hand, when the power generation amount of one photovoltaic power generation panel 104 decreases, one LED lamp 202 is turned on. The LED lamp 202 that is lit is the LED lamp 202 that connects the anode side to the output side of the photovoltaic power generation panel 104 on which the power generation amount has not decreased. Therefore, if each of the photovoltaic power generation panels 104 and the LED lamp 202 having the cathode side connected to the output side thereof are associated with each other as a set, the LED lamp 202 corresponding to the photovoltaic power generation panel 104 having a reduced power generation amount. Can be turned on.

  Moreover, in the failure detection circuit 204 of this example, a Zener diode TD is interposed on the anode side of the LED lamp 202. Thereby, when the power generation amount of one photovoltaic power generation panel 104 decreases, the LED lamp 202 can be lit only when the voltage decreases to the Zener voltage of the Zener diode TD. Accordingly, it is possible to avoid the inconvenience that the corresponding LED lamp 202 is suddenly turned on when the power generation amount of one of the solar power generation panels 104 is slightly reduced.

Figure 7 is a schematic diagram showing an example of a LED lamp arrangement unit及 beauty indicia. Diagnostic device A photovoltaic panel 104 of this embodiment also has an LED lamp arrangement unit及 beauty indicia. More specifically, the failure detection unit 201 (see FIG. 2) of the first example uses the LED lamp arrangement unit as an essential component, whereas the failure detection unit 201 (see FIG. 5) of the second example The LED lamp arrangement part is not an essential component. Here, it says the LED lamp arrangement unit is a structure disposed adjacent the pair of LED lamps 202. As described above, the failure detection unit 201 of the first example compares the light emission states of the pair of LED lamps 202 associated with the two adjacent solar power generation panels 104 and determines one of the solar power generations based on human judgment. Diagnose a failure of the panel 104. Therefore, the condition of adjacent arrangement is required for the pair of LED lamps 202. In the example shown in FIG. 7, a pair of LED lamps 202 are arranged adjacent to each other in a vertical row in the frame portion of each photovoltaic power generation panel 104, thereby forming an LED lamp arrangement unit .

On the other hand, both the failure detection unit 201 of the first example (see FIG. 2) and the failure detection unit 201 of the second example (see FIG. 5) both require the labeling unit. And Say the indicia is indicative symbolizes the correspondence between the pair of LED lamps 202 and two solar panels 104. Here, “symbolization” refers to giving meaning contents to symbols such as colors, characters, and arrangements, here, meaning contents of which photovoltaic power generation panel 104. In the example illustrated in FIG. 7, different colors between the pair of LED lamps 202 are used as symbols. For example, the upper LED lamp 202 is blue, and the lower LED lamp 202 is red. In this case, it is preferable to cover the pair of LED lamps 202 with blue and red light-transmitting covers, instead of color-coding according to the emission colors of the LEDs themselves constituting the LED lamp 202. As an example, the LED lamp 202 pointing to the photovoltaic power generation panel 104 on which the pair of LED lamps 202 is arranged corresponds to blue, and the LED lamp 202 pointing to the photovoltaic power generation panel 104 adjacent to the left side thereof corresponds to red. .

That is, the marking unit illustrated in FIG. 7 gives the meaning content that the photovoltaic power generation panel 104 in which the pair of LED lamps 202 is arranged is associated with the blue LED lamp 202, and the red LED lamp The meaning content that the adjacent photovoltaic power generation panel 104 is associated with 202 is assigned to 202. Therefore, the marking part sets artificial rules.

  Therefore, when the failure detection unit 201 (see FIG. 2) of the first example is adopted, if the light emission intensity of the red LED lamp 202 is lower than that of the blue LED lamp 202, a pair of LED lamps 202 is arranged. It can be seen that the amount of power generated by the photovoltaic power generation panel 104 adjacent to the left side of the photovoltaic power generation panel 104 being reduced is reduced. On the contrary, if the emission intensity of the blue LED lamp 202 is lower than that of the red LED lamp 202, the amount of power generated by the photovoltaic power generation panel 104 in which the pair of LED lamps 202 is disposed is reduced. I understand. In this way, it is possible to easily diagnose a decrease in the amount of power generation in any one of the photovoltaic power generation panels 104.

  On the other hand, when the failure detection unit 201 (see FIG. 5) of the second example is adopted, the solar power generation panel 104 adjacent to the left side of the solar power generation panel 104 in which the pair of LED lamps 202 is arranged. If the power generation amount decreases, the failure detection circuit 204 turns on the red LED lamp 202. On the other hand, if the power generation amount of the solar power generation panel 104 in which the pair of LED lamps 202 is disposed decreases, the failure detection circuit 204 turns on the blue LED lamp 202. In this way, it is possible to easily diagnose a decrease in the amount of power generation in any one of the photovoltaic power generation panels 104.

Figure 8 is a schematic view showing another example of a LED lamp arrangement unit及 beauty indicia. FIG. 9 is an enlarged front view showing the marking portion . The sign part illustrated in FIG.8 and FIG.9 distinguishes a pair of LED lamp 202 with the symbol of a character, without color-coding. That is, of the pair of LED lamps 202 arranged adjacent to each other in a vertical row, an English letter “LEFT” is written under the LED lamp 202 positioned below. The symbol of the letter “LEFT” indicates that the LED lamp 202 located below corresponds to the photovoltaic panel 104 adjacent to the left side of the photovoltaic panel 104 where the pair of LED lamps 202 is arranged. The meaning content of the lamp 202 is generated. As a reflective effect, the English letter symbol “LEFT” means that the LED lamp 202 located above is an LED lamp 202 corresponding to the photovoltaic power generation panel 104 in which the pair of LED lamps 202 is disposed. It also gives rise to content. That is, the English letter “LEFT” clearly indicates that the LED lamp 202 positioned below corresponds to the photovoltaic panel 104 adjacent to the left side of the photovoltaic panel 104 where the pair of LED lamps 202 is arranged. This implies that the LED lamp 202 positioned above corresponds to the photovoltaic power generation panel 104 on which the pair of LED lamps 202 are arranged.

  Therefore, when the failure detection unit 201 (see FIG. 2) of the first example is employed, if the light emission intensity of the lower LED lamp 202 is lower than the upper LED lamp 202, the pair of LED lamps 202 is used. The decrease in the amount of power generated by the photovoltaic power generation panel 104 adjacent to the left side of the photovoltaic power generation panel 104 in which the is placed can be clearly shown to the observer. On the other hand, if the emission intensity of the LED lamp 202 at the upper position is lower than the LED lamp 202 at the lower position, the decrease in the amount of power generated by the photovoltaic power generation panel 104 in which the pair of LED lamps 202 is arranged is observed. Can imply it. In this way, it is possible to easily diagnose a decrease in the amount of power generation in any one of the photovoltaic power generation panels 104.

  In addition to this, when the failure detection unit 201 (see FIG. 2) of the first example is employed, it is preferable that the pair of LED lamps 202 is formed of a plurality of LEDs each having a different emission color. . As is well known, the difference in the emission color is caused by the difference in the material constituting the LED, and therefore the voltage sufficient to emit light differs depending on the color. Therefore, if the LED lamp 202 is formed by a plurality of LEDs having different emission colors, the emission color of the corresponding LED lamp 202 changes according to the decrease in the amount of power generated by the photovoltaic power generation panel 104. Therefore, it is possible to indicate to the observer how the power generation amount of the photovoltaic power generation panel 104 is reduced by the emission color of the LED lamp 202.

  On the other hand, when the failure detection unit 201 (see FIG. 5) of the second example is adopted, the solar power generation panel 104 adjacent to the left side of the solar power generation panel 104 in which the pair of LED lamps 202 is arranged. If the power generation amount decreases, the failure detection circuit 204 turns on the LED lamp 202 at the lower position. At this time, the symbol of the letter “LEFT” clearly indicates to the observer that the power generation amount of the photovoltaic power generation panel 104 is reduced. On the other hand, if the power generation amount of the photovoltaic power generation panel 104 in which the pair of LED lamps 202 is disposed decreases, the failure detection circuit 204 turns on the LED lamp 202 at the upper position. At this time, the symbol of the letter “LEFT” implies to the observer that the power generation amount of the photovoltaic power generation panel 104 is reduced. In this way, it is possible to easily diagnose a decrease in the amount of power generation in any one of the photovoltaic power generation panels 104.

Figure 10 is a schematic diagram illustrating yet another example of a LED lamp arrangement unit及 beauty indicia. The sign part illustrated in FIG. 10 symbolizes the correspondence between the pair of LED lamps 202 and the two photovoltaic power generation panels 104 according to the arrangement positions of the individual LED lamps 202. That is, in FIG. 10, the LED lamp 202 disposed on the left shoulder of the solar power generation panel 104 located in the center is associated with the solar power generation panel 104. The LED lamp 202 disposed on the right shoulder of the photovoltaic power generation panel 104 adjacent to the left side of the photovoltaic power generation panel 104 is associated with the photovoltaic power generation panel 104. And the LED lamp 202 located on the left shoulder of the photovoltaic power generation panel 104 located in the center and the LED lamp 202 arranged on the right shoulder of the photovoltaic power generation panel 104 adjacent to the left side thereof are arranged adjacent to each other. ing. As a result, these LED lamps 202 constitute a pair of LED lamps 202 respectively corresponding to the photovoltaic power generation panel 104 located in the center thereof and the photovoltaic power generation panel 104 adjacent to the left side thereof. It is shown.

  Therefore, when the failure detection unit 201 (see FIG. 2) of the first example is adopted, the photovoltaic panel 104 adjacent to the left side of the LED lamp 202 on the left shoulder of the photovoltaic panel 104 located in the center is adjacent. If the light emission intensity of the LED lamp 202 on the right shoulder is reduced, it can be shown to the observer that the power generation amount of the photovoltaic power generation panel 104 adjacent to the left is reduced. On the other hand, if the LED light 202 on the left shoulder of the photovoltaic panel 104 located in the center is more than the emission intensity of the LED lamp 202 on the right shoulder of the photovoltaic panel 104 adjacent to the left next to the center. If the light emission intensity decreases, it is possible to indicate to the observer a decrease in the amount of power generated by the photovoltaic power generation panel 104 located in the center. In this way, it is possible to easily diagnose a decrease in the amount of power generation in any one of the photovoltaic power generation panels 104.

  In addition to this, when the failure detection unit 201 (see FIG. 2) of the first example is employed, it is preferable that the pair of LED lamps 202 is formed of a plurality of LEDs each having a different emission color. . As is well known, the difference in the emission color is caused by the difference in the material constituting the LED, and therefore the voltage sufficient to emit light differs depending on the color. Therefore, if the LED lamp 202 is formed by a plurality of LEDs having different emission colors, the emission color of the corresponding LED lamp 202 changes according to the decrease in the amount of power generated by the photovoltaic power generation panel 104. Therefore, it is possible to indicate to the observer how the power generation amount of the photovoltaic power generation panel 104 is reduced by the emission color of the LED lamp 202.

  On the other hand, when the failure detection unit 201 (see FIG. 5) of the second example is adopted, if the power generation amount of the photovoltaic power generation panel 104 adjacent to the left of the center portion decreases, the failure detection circuit 204 The LED lamp 202 on the right shoulder is turned on. On the contrary, if the power generation amount of the photovoltaic power generation panel 104 located in the center portion is reduced, the failure detection circuit 204 turns on the LED lamp 202 on the left shoulder. In this way, it is possible to easily diagnose a decrease in the amount of power generation in any one of the photovoltaic power generation panels 104.

The failure detection unit 201 included in the solar power generation panel 104 has been described above based on FIGS. On the other hand, the failure detection unit 301 included in the connection box 107 can employ a configuration similar to that of the failure detection unit 201. In other words, the light emitting circuit 303 included in the failure detection unit 301 arranges the LED lamps 302 associated with the individual systems 109, for example, as an example. The individual LED lamps 302 can be associated with each system 109 by applying symbolization such as color coding, characters, and arrangement, in other words, by adopting a configuration equivalent to the marking unit . Thus, by comparing the light emission states of the individual LED lamps 302, the observer can diagnose the state of the power generation amount of the solar power generation panel 104 with each system 109 as a unit.
