Patent number: 10326281Abstract: A power conditioner (12) includes a detector (15) and a controller (19). The detector (15) detects electrical output of each of a plurality of photovoltaic cell modules (11). The controller (19) compares a change over time in the electrical output detected by the detector (15) with a threshold. When the change over time exceeds the threshold for a plurality of photovoltaic cell modules (11) and the photovoltaic cell modules (11) are in a predetermined positional relationship, the controller (19) causes the photovoltaic cell modules (11) to perform a maximum power point search.Type: GrantFiled: March 7, 2014Date of Patent: June 18, 2019Assignee: KYOCERA CorporationInventor: Masanori Nishimori
