<p>PROBLEM TO BE SOLVED: To prevent generated power by a photovoltaic power generation from exceeding a load power of a load device.SOLUTION: A photovoltaic power generation control device 30 is connected to a photovoltaic power generation device 10 and a DC power supply system 20 for consuming or accumulating a DC power. The photovoltaic power generation device 30 includes: a circuit 100 for inputting generated power by a photovoltaic power generation from the photovoltaic power generation device 10 and outputting the input generated power to the DC power supply system 20; and a micro-computer 32. The micro-computer 32 includes an output voltage detection part 33 for detecting a voltage of an output side of the power in the circuit 100; a comparison part 34 for comparing the voltage and a threshold value of the detected output side; and an operation voltage control part 36 for controlling the operation voltage of the photovoltaic generation in such a manner to separate from the optimum operation voltage in which the generated power by the photovoltaic generation becomes the maximum when it is determined that the voltage of the output side is larger than the threshold value.</p> |
