Attach while performing wiring and piping connection between adjacent modules. The piping is connected by rubber hoses (not shown) between both header tubes 29 (described later), and both ends of the hoses are fixed by hose bands (not shown) so that the heat medium does not leak. If necessary, a spacer 13 or the like may be attached to the lower frame 11 so that the header tube 29 does not come into contact therewith. These wirings and pipes are drawn into the building unit A from the through holes 39 formed in the eaves frame 8 as shown in FIG.

After all the solar energy utilization device main bodies 4 are set, the upper frame 12 is placed on the solar energy utilization device main body 4

[Modification] As a first modification of the first embodiment, as shown in FIG. 8, a solar energy utilization device main body 4 such as a solar cell module 40 can be used.

The solar cell module 40 uses PVF instead of the heat collecting plate 19 of the solar / heat hybrid module 3.
It is provided with a back film such as a metal sheet coated on both sides with (vinyl fluoride resin). Since the solar cell module 40 does not need to be provided with the heat collecting plate 19, it can be made thinner than the solar / heat hybrid module 3. Therefore, the material and the like of the urethane resin portion excluding the heat collecting plate 19 can be suppressed as compared with the solar / heat hybrid module 3. This manufacturing process is substantially the same as that of the solar-heat hybrid module 3 except for the process of forming the heat insulating layer 21.

As described above, according to the first aspect of the present invention, the risk of being buried by snow can be reduced by mounting the solar energy utilization device body on the side of the eaves of the flat roof. The installation workability is improved, and the work time can be shortened. In addition, because the angle of inclination of the solar energy utilization device body is large, it can be installed almost perpendicular to the incident angle of sunlight, and since it is not buried even during snowfall, it can collect heat and generate electricity. It is possible to use solar energy without waste throughout the year. Therefore, the solar energy utilization device main body can be further spread.

According to the second aspect of the present invention, by attaching the lower frame to the eaves frame, it is possible to exhibit a practically useful effect that the mounting strength can be increased.
