SOLAR POWER GENERATION SYSTEM AND CONTROL METHOD

A solar power generation system includes a solar power generation device, a load device, and a control device. The control device includes a switching control unit for executing switching control for starting power supply to the load device when electric energy generated by the solar power generation device is equal to or larger than a starting threshold value and stopping the power supply to the load device when the electric energy becomes equal to or smaller than a stopping threshold value, a number-of-times acquiring unit for acquiring the number of times of execution of the switching control, and a threshold setting unit for increasing or reducing at least one of the staring threshold value and the stopping threshold value based on whether the number of times of execution acquired by the number-of-times acquiring unit within a first predetermined period has reached a predetermined first upper limit number of times.
