Therefore, the temperature rise of the photovoltaic power generation panel 3 can be effectively suppressed, and the decrease in power generation efficiency of the photovoltaic power generation panel 3 can be suppressed.

  Furthermore, in the mounting structure according to the first to fourth embodiments of the present invention, the air guide plate 4 (5) has the protruding piece 400 (50) extended in the eaves-ridge direction D1, and the protruding piece 400 (50). Is connected to the support 9 (11).

  According to the mounting structure of each embodiment, the wind guide plate 4 (5) is placed at an appropriate location in the air layer 7 by using the support 9 (11) that supports the photovoltaic power generation panel 3 on the inclined roof 1. Can be installed. Therefore, it is possible to install the air guide plate 4 (5) without the need to separately process the inclined roof 1 such as drilling.

  Furthermore, in the attachment structure of 4th Embodiment of this invention, the ventilation mechanism 8 which forcibly sends out the air in the air layer 7 toward the building side of the eaves building direction D1 is further provided.

  According to the mounting structure of the fourth embodiment, the air flow F1 guided by the air guide plate 4 (5) and passing through the upper region can be generated in the air layer 7 with a forced air volume. Therefore, the temperature rise of the photovoltaic power generation panel 3 can be further effectively suppressed, and the decrease in power generation efficiency of the photovoltaic power generation panel 3 can be further suppressed.

  Furthermore, in the mounting structure of the first embodiment of the present invention, the inclined roof 1 is an uneven roof having alternating convex portions 121 that open downward and concave portions 120 that open upward. Therefore, in addition to the space formed between the convex portion 121 and the photovoltaic power generation panel 3, air easily flows in the eaves-ridge direction D1 through the space formed between the concave portion 120 and the photovoltaic power generation panel 3. It has a structure.

  As mentioned above, although this invention was demonstrated based on embodiment shown to an accompanying drawing, this invention is not limited to the structure of each above-described embodiment. Within the range intended by the present invention, it is possible to make appropriate design changes to the embodiments and to combine the configurations of the embodiments.
