  In this case, the support frame member that supports the photovoltaic power generation panel is prevented from rising toward the one locking groove in the one locking groove provided on the exterior material and positioned on the upper side. It is desirable that an anti-raising member is further mounted.

  In addition, in a preferred embodiment, at least the upper and lower positions of the support frame member that supports the solar power generation panel have air circulation holes that communicate the space between the solar power generation panel and the exterior material and the outside. Each is formed.

According to the mounting structure of the photovoltaic panel to the exterior material described above, the photovoltaic power panel supported by the support frame member is formed so as to face each other vertically along the surface side of the exterior material. Can be installed using.
In this case, the spring members are respectively attached to the upper and lower sides of the support frame member, and first, the upper frame of the support frame member is inserted into the locking groove on the upper side of the exterior material together with the spring member, and then the exterior material By performing a so-called “raising and dropping” operation in which the lower frame of the support frame member is dropped together with the spring member into the lower locking groove, the photovoltaic panel can be easily applied to the exterior material. Can be attached to.
Further, when replacing the photovoltaic power generation panel, the photovoltaic power generation panel can be easily detached from the exterior material by an operation reverse to that described above.

  Furthermore, since the above-described spring member works to urge the photovoltaic power generation panel in one direction, for example, to urge the photovoltaic power generation panel in a direction away from the exterior material, the power generation attached to the exterior material For example, it is possible to avoid problems such as the panel receiving a wind pressure, rattling and generating noise.
