PROBLEM TO BE SOLVED: To prevent a solar panel from being scattered, exfoliated and damaged at the time of strong wind, due to its configuration, while allowing suppression of output voltage drop by suppressing temperature rise of the solar panel, with a relatively simple configuration.SOLUTION: On the back side of a solar panel 4, distributors 8 are attached oscillatably, in three stages vertically, to a support frame for supporting the upper part of the solar panel 4. First, second and third electric motors, capable of being driven forward and reversely, are linked and coupled with the distributors 8 of three stages. These electric motors are linked each other and the three distributors 8 are driven synchronously, so that switching is made between the ventilation state where the outside air flows to the back of the solar panel 4, and the security state where the outside air is blocked. When the wind speed measured by an anemometer does not exceed a set wind speed, the distributors 8 are brought into the ventilation state, thus suppressing temperature rise of the solar panel. Meanwhile, when the wind speed measured by the anemometer exceeds the set wind speed, the distributors 8 are switched to the security state.SELECTED DRAWING: Figure 5 |
