<P>PROBLEM TO BE SOLVED: To provide a ventilation facility in which high power generation efficiency of a photovoltaic power generation system is obtained while regulating ventilation volume in accordance with seasons. <P>SOLUTION: A ventilation facility includes a ventilation port 21 formed on a roof surface, a cover part 23 opening/closing the ventilation port 21, a photovoltaic power generation array 24 provided in the cover part 23, an actuator 25 which adjusts an aperture of the cover part 23, and a control device 26. The control device 26 sets a tilting angle of the cover part 23 for each season with an angle to a horizontal surface as a tilting angle. According to the present invention, since the tilting angle of the cover part 23 is adjusted for each season by driving the actuator 25, power generation efficiency of photovoltaic power generation can be improved while regulating ventilation volume in accordance with seasons. <P>COPYRIGHT: (C)2012,JPO&INPIT |
