PROBLEM TO BE SOLVED: To provide a solar battery system practically using spectator's seat backrest parts of stand seats having a large area and a large upper space in a stadium as a photovoltaic power generation area.SOLUTION: Many spectator's seats 1 become vacant a day except dates for big events using wide stand seats overall of annual management of a stadium, and this large area and large upper space become an area capable of being practically used for new photovoltaic power generation. Solar battery modules 2 are connected and fixed to spectator's seat backrest parts of the stand seats in which the wide upper space occurs by fixtures 3, output circuits of the solar battery modules 2 of the solar battery module-equipped spectator's seat are arranged into one in a unit of the stand seat to be set as a stand seat-classified solar battery array, and output circuits of the solar battery arrays of the respective stand seats are arranged into one to configure a solar battery system supplying power by the photovoltaic power generation. |
