In addition, it may further include a power inverting device for collecting the generated power received from the at least one photovoltaic module 100, specifically, the generated voltage or current, and inverting the generated voltage or current into a DC/AC voltage.

At least one photovoltaic module 100 is configured such that a plurality of solar cells are arranged in a rectangular or curved frame in an n×m shape, and generated power is generated using each of the solar cells. Here, n and m are natural numbers that are the same as or different from each other except 0. Through each of the solar cells arranged in this way, it is possible to generate a DC or AC voltage and generate a current. The generated DC or AC voltage and current are collectively transmitted to the power inverting device as generated power.
