It is determined whether it is within the display range of the quantity display button image. When it determines with power generation amount display operation not being performed (step S14: NO), the control part 41 returns a process to step S11, and continues the display of an operation condition image. When it is determined that the power generation amount display operation has been performed (step S14: YES), the control unit 41 displays the past power generation amount (step S15). That is, the control part 41 performs the process which displays the graph display of the past power generation amount by the photovoltaic power generation system 1 and the power consumption amount in the household load 3 in a year, a month, or a day. This will be specifically described below.
