  By the way, in a solar power generation device, in order to obtain more electric energy by each solar cell panel, the solar cell panels are usually arranged closely in parallel along the upper surface of the foundation. Thus, a larger number of solar cell panels are juxtaposed in a limited area on the ground. For this reason, the space between the upper surface of the foundation and each solar cell panel tends to be a tightly closed space, that is, tends to be a poorly ventilated space.

  Therefore, in the solar power generation device having the above-described configuration, heat radiation from around each solar cell panel toward the atmosphere becomes insufficient, and the ambient temperature around each solar cell panel may become high. And when it becomes high temperature in this way, there exists a possibility that the energy conversion performance from the light energy in each said solar cell panel to an electrical energy may be inhibited, or a lifetime may fall.

  The present invention has been made paying attention to the above-described circumstances, and the object of the present invention is to provide a plurality of solar battery panels when a plurality of solar battery panels are supported on a concrete base installed on the ground. The energy conversion performance from light energy to electrical energy is maintained satisfactorily, and the lifetime of these solar cell panels can be improved.
