びだすことができる。As described above, according to the present invention, by installing a solar cell panel arranged in a corrugated shape above a flat support plate, the support plate and the solar cell panel can be connected to each other. A heat collector is formed between the heat collectors, and both end faces of the heat collector are closed by a pair of end walls having vent holes, so that an airflow flowing from one vent hole to the other vent hole is formed in the heat collector. Then, the heat in the heat collecting section can be carried out of the heat collecting section by riding this air flow.

陽光エネルギーの利用率を高めることができる。Further, the utilization rate of solar thermal energy can be increased by, for example, guiding the heated air flow carried out from the heat collecting section to indoors for heating. Furthermore, since the solar cell panels are arranged in a corrugated shape, the light receiving area is larger than the installation plane area, and the utilization rate of solar energy per installation plane area can be increased.

太陽熱エネルギーを利用できるようになる。In the present invention, in particular, when a pair of end plates for closing both ends of the heat collecting section are provided and each end plate is formed with a vent, the shape of the vent is circular, square or rectangular. For example, it can be formed in an arbitrary shape corresponding to the cross-sectional shape of a duct that normally conducts gas, and it becomes easy to connect a duct having a blower and forcibly form an airflow in a heat collecting portion. By forcibly forming an airflow in the heat collecting section, the solar cell panel can be cooled more efficiently, and it is possible to prevent overheating of the solar cell panel, a decrease in output due to the overheating, and a reduction in battery life, and further increase the efficiency. The solar thermal energy can be used well.

The configuration is simpler than that of the device, and the number of components can be reduced by omitting components such as connection fittings, thereby achieving cost reduction.
