PROBLEM TO BE SOLVED: To obtain a photovoltatic power generation system which can output AC electric power simply as long as the sunlight is available even in a shelter at a disaster by a method wherein a power conversion device which converts the light energy of the sun and DC electric power into AC electric power is housed in one housing box. SOLUTION: A solar cell 1 is formed to be of a folding type. A power conversion device 2 converts the DC output of the solar cell into an alternating current. A storage battery 3 charges and discharges electric power. A housing box 4 houses the solar cell 1, the power conversion device 2 and the storage battery 3. Thereby, even in a disorder state at a disaster or the like, anybody can set the solar sell simply at an optimum angle. In addition, since the number of interconnections is small, the efficiency of a photovoltatic power generation system can be enhanced, the system can be carried as the power generation device, and the system can be used in any place whenever the sunlight is available. |
