Zusammenfassung:PROBLEM TO BE SOLVED: To solve the problem that, in the case where a failure occurs in a photovoltaic power generation system, if it takes time for a requirement to a repairer, a power generation amount during that period may be lost and regarding power generation amount reduction caused by any other factor than the failure, if the failure is left, a loss may be increased by accumulating power generation shortage, thereby making a user unprofitable as a result.SOLUTION: In a power generation amount monitoring system, a power generation data output device which performs measurement of power generation of the photovoltaic power generation system and setting of a standard power generation amount, a power generation data management device for calculating a power generation amount during a predetermined period and comparing the power generation amount with a standard power generation amount, and a service terminal device are connected over a network. The power generation data management device monitors an actual power generation amount of the photovoltaic power generation system and transmits a result of comparison with the standard power generation amount to the service terminal device.SELECTED DRAWING: Figure 3 【課題】太陽光発電システムが故障した際、修理業者への依頼などに時間がかかると、その期間の発電量を損失することになる。また、故障ではない別の原因による発電量低下については放置しておけば発電不足が蓄積されて損失が増え、使用者の不利益に繋がる。【解決手段】 本発明の発電電力量監視システムでは、太陽光発電システムの発電電力の測定と標準発電電力量の設定を行う発電データ出力装置と、所定期間における発電電力量の算出および標準発電電力量との比較を行う発電データ管理装置と、サービス端末装置とをネットワークを介して接続し、発電データ管理装置が太陽光発電システムの実発電電力量を監視して標準発電電力量との比較結果をサービス端末装置に送信するように構成した。【選択図】 図3
