Zusammenfassung:PROBLEM TO BE SOLVED: To provide a solar energy utilization system capable of suppressing a secondary battery capacity.SOLUTION: Provided is a system 1 including a power generation unit 10 that can generate electric power using sunlight; and a heat collection unit that can collect heat from the power generation unit 10, capable of generating the electric power using the sunlight, and capable of using the heat obtained as the power generation unit 10 generates the electric power. The system comprises: a secondary battery 80 that can be charged with the electric power; a heat collection pump 40, a hot water pump 60, and a control circuit 90 used for the system 1 to operate; a first circuit that supplies the electric power generated by the power generation unit 10 to the hot water pump 60 and the control circuit 90 that are part of the load from the secondary battery 80 after the secondary battery 80 is charged with the electric power; and a second circuit that supplies the electric power generated by the power generation unit 10 to the heat collection pump 40 that is part of the load and that differs from the first load without charging the secondary battery 80 with the electric power. The system 1 can operate autonomously. 【課題】蓄電池容量を抑制することができる太陽エネルギー利用システムを提供する。【解決手段】太陽光を利用して発電可能な発電部10と、発電部10の熱を集熱可能な集熱部と、を具備し、太陽光を利用して発電可能であると共に発電に伴って得られる熱を利用可能なシステム1であって、電力を充電することが可能な蓄電池80と、システム1を運転するために使用される集熱ポンプ40、出湯ポンプ60及び制御回路90と、発電部10において発電された電力を、蓄電池80に充電した後に、当該蓄電池80から前記負荷の一部である出湯ポンプ60及び制御回路90に供給する第一系統と、発電部10において発電された電力を、蓄電池80に充電することなく、前記負荷の一部であり前記第一負荷とは異なる集熱ポンプ40に供給する第二系統と、を具備し、自立運転が可能である。【選択図】図2
