[Problems to be solved by the present disclosure]
When dirt such as sand adheres to the light receiving surface of the concentrating solar power generation device, the power generation efficiency of the concentrating solar power generation device decreases. The concentrating solar power generation device may be placed in a desert area as a place with good sunshine conditions, for example. In a desert area, a sandstorm frequently occurs, and the light-receiving surface of the concentrating solar power generation device is covered with sand due to the sandstorm. When the light receiving surface is covered with sand, the power generation efficiency of the concentrating solar power generation device is significantly reduced.

(4) If it is possible to predict that a sand storm will occur, directing the light-receiving surface downward immediately before the sand storm will prevent sand from adhering to the light-receiving surface. When sand adheres to the light receiving surface, dirt such as sand is removed with the light receiving surface facing downward. In addition to the cleaning of the light-receiving surface, the light-receiving surface may be turned downward for repair, maintenance, and the like of the concentrator photovoltaic power generator.

る と When the light receiving surface (front surface) faces downward, the back surface of the concentrator photovoltaic module faces upward. Cables and connectors for connecting the modules are arranged on the back surface of the concentrating solar power module. For this reason, when the back surface of the concentrating photovoltaic module faces upward, the cables and connectors are exposed to direct sunlight. Since each of the cable and the connector is made of a resin material, the cable and the connector are easily deteriorated by exposure to ultraviolet rays contained in direct sunlight. For this reason, the long-term life of the concentrating solar power generation device is not ensured.

目的 An object of the present disclosure is to provide a concentrator photovoltaic module and a concentrator photovoltaic device that can easily extend the life.

That is, the cables 21a and 21b and the connectors 22a and 22b are sandwiched between the bent portion 1ba of the shielding member 1b and the second surface 1ab of the bottom plate 1a. The cable 21a is electrically connected to the power generating element 3 via the junction box 20. A connector 22a is connected to a distal end of the cable 21a. That is, the cable 21a electrically connects the power generating element 3 and the connector 22a.

The connector 22a is a male connector, for example, and can be connected to the female connector 22b. The connectors 22a and 22b are made of, for example, resin. The connector 22a may be a female type and the connector 22b may be a male type. The cable 22b is connected to the connector 22b. In the drawing, the connector 22a and the connector 22b are shown in a disconnected state.

The connectors 22a and 22b are located outside the housing 4 on the first opening end 4b side with respect to the second opening end 4c of the housing 4. In the present embodiment, the connectors 22a and 22b are arranged on the second surface 1ab of the bottom plate 1a (the side opposite to the housing 4 with respect to the bottom plate 1a). The connectors 22a and 22b are covered with the bent portion 1ba of the shielding member 1b on the side opposite to the second opening end 4c with respect to the connectors 22a and 22b.

At least some of the cables 21a and 21b are also arranged on the second surface 1ab of the bottom plate 1a. At least a portion of the cables 21a and 21b is covered by a bent portion 1ba of the shielding member 1b on a side opposite to the second opening end 4c with respect to at least a portion of the cables 21a and 21b.

The shielding member 1b is arranged so as not to cover the second area on the second surface 1ab located behind the first area on the first surface 1aa of the bottom plate 1a on which the power generating element 3 is arranged. When the plurality of power generating elements 3 are arranged on the first surface 1aa of the bottom plate 1a, the shielding member 1b does not cover the area of the second surface 1ab located behind the area RA where the plurality of power generating elements 3 are densely packed. It is preferable that the openings are formed as follows. The area RA is an area surrounding the plurality of power generation elements 3.

The shielding member 1b may be configured by bending the member 1 integrated with the bottom plate 1a. The shielding member 1b is made of a separate component from the bottom plate 1a, and may be attached to the bottom plate 1a with, for example, an adhesive. The shielding member 1b is made of a separate component from the bottom plate 1a, and may be detachably attached to the bottom plate 1a by, for example, a hook-and-loop fastener.

Next, the operation and effect of the present embodiment will be described.
Conventionally, the second surface 1ab of the bottom plate 1a is not covered with a cover or the like so that heat does not remain on the second surface 1ab (back surface) of the bottom plate 1a of the concentrator photovoltaic module 10, and it is exposed to the outside air. It had been exposed.

However, in this state, if the light receiving surface is turned downward for cleaning the surface (light receiving surface) of the lens member 9 as described above, the back surface of the concentrating solar power generation module 10 (the second surface 1ab of the bottom plate 1a). Face upward, and the cables 21a, 21b and the connectors 22a, 22b are exposed to direct sunlight. As a result, each of the cables 21a and 21b and the connectors 22a and 22b deteriorates, and the long-term life of the concentrator photovoltaic power generator 30 is not ensured.

In this embodiment, as shown in FIGS. 4 to 6, the shielding member 1b covers the connectors 22a and 22b on the opposite side of the connectors 22a and 22b from the second opening end 4c side. . Therefore, when the second opening end 4c to which the lens member 9 is attached faces downward, the upper side of the connectors 22a and 22b is covered by the shielding member 1b. Accordingly, even when the lens member 9 faces downward, the sunlight is blocked by the blocking member 1b, so that the sunlight is not directly applied to the connectors 22a and 22b. Therefore, deterioration of the connectors 22a and 22b due to ultraviolet rays is suppressed, and it becomes easy to extend the life of the concentrating solar power generation module 10.

In the present embodiment, as shown in FIGS. 4 to 6, at least a part of the cables 21a and 21b is a shielding member on the opposite side of the cables 21a and 21b from the second opening end 4c. 1b. Thus, when the second opening end 4c to which the lens member 9 is attached faces downward, the shielding member 1b covers at least a part of the upper side of the cables 21a and 21b. Accordingly, even when the lens member 9 faces downward, the sunlight is blocked by the blocking member 1b, so that at least a part of the cables 21a and 21b is not directly irradiated. Therefore, deterioration of at least a part of the cables 21a and 21b due to ultraviolet rays is also suppressed, and it becomes easier to prolong the life of the concentrating solar power generation module 10.

In the present embodiment, the shielding member 1b shown in FIGS. 4 to 6 may be configured by bending a member integrated with the bottom plate 1a. Thereby, the number of parts can be reduced.

In the present embodiment, the shielding member 1b shown in FIGS. 4 to 6 may be attached to the bottom plate 1a. This increases the degree of freedom of the position of the shielding member 1b with respect to the bottom plate 1a. Also, the pasting process is easy.

In this embodiment, the shielding member 1b shown in FIGS. 4 to 6 may be detachably attached to the bottom plate 1a. This makes it possible to attach the shielding member 1b to the bottom plate 1a only when the connectors 22a and 22b want to avoid irradiation of sunlight.

(4) Even when the shielding member 1b is arranged so as to avoid the back surface side of the arrangement area RA (FIGS. 2 and 5) of the power generation element 3, heat may be trapped between the shielding member 1b and the bottom plate 1a. Further, the shielding member 1b may obstruct the transportation, and it may be difficult to install the connectors 22a and 22b and the cables 21a and 21b.

If the shielding member 1b is detachable from the bottom plate 1a, the shielding member 1b can be detached from the bottom plate 1a except when the lens member 9 faces downward. When the shielding member 1b is detached from the bottom plate 1a, heat does not stay between the shielding member 1b and the bottom plate 1a, and the shielding member 1b becomes an obstacle when the concentrating solar power generation module 10 is transported. Nor.

In addition, in the present embodiment, as shown in FIG. 5, the shielding member 1b is opened so as not to cover the region on the back surface (the second surface 1ab) side of the region where the power generating element 3 is arranged. This prevents heat from being trapped on the back side of the power generating element 3, thereby preventing a decrease in power generation efficiency or deterioration of members of the power generating element 3 due to high temperature.

{Circle around (2)} The shielding member 1b is arranged so as not to cover the region on the back surface (the second surface 1ab) side of the region RA where the plurality of power generating elements 3 are arranged. This further prevents heat from being trapped on the back side of the power generation element 3, thereby preventing a reduction in power generation efficiency or deterioration of members of the power generation element 3 due to high temperature.

Further, in the present embodiment, as shown in FIGS. 4 to 6, the shielding member 1b has a rising portion 1bb rising from the second surface 1ab of the bottom plate 1a and a bent portion 1ba bent from the rising portion 1bb. Have. The bent portion 1ba sandwiches the connectors 22a and 22b between the bent portion 1ba and the bottom plate 1a. By configuring the shielding member 1b in this manner, a gap for sandwiching the connectors 22a and 22b can be easily provided between the bent portion 1ba and the second surface 1ab.

In addition, in the present embodiment, as shown in FIG. 6, the cross-sectional shape of the rising portion 1bb is a linear shape. Thereby, the processing of the rising portion 1bb is easy.

In the present embodiment, as shown in FIG. 1, the concentrating solar power generation device 30 includes a driving device 14, and the driving device 14 allows the concentrating photovoltaic power generation module 10 to move the sun. It can be driven so as to perform a tracking operation and the lens member 9 faces downward. Accordingly, even when the lens member 9 faces downward, the sunlight is blocked by the blocking member 1b, so that the sunlight is not directly applied to the connectors 22a and 22b. Therefore, the deterioration of the connectors 22a and 22b due to ultraviolet rays is suppressed, and the life of the concentrating solar power generation device 30 can be easily extended.
