Abstract:
1. A solar cell system comprising: a solar cell; a load controller configured to be connected to the solar cell, the load controller being capable of controlling a load applied to the solar cell; an output measuring unit configured to measure a power generation output of the solar cell; an output predicting unit configured to predict a value to be reached by the output on a basis of transient response of the output measured by the output measuring unit, wherein the solar cell system has a function of controlling the load controller so as to maximize the value to be reached; and a power generation control system, wherein the power generation control system performs a process of dividing a load range from a minimum load condition to a maximum load condition of the load controller into n parts (n≧3), performing output prediction under each of n load conditions in the output predicting unit, and outputting the load condition providing a largest output value from n predicted output values obtained, the power generation control system performs a process of further dividing a load range including the output load condition into n parts, performing output prediction under each of n load conditions, and outputting the load condition providing a largest output value from n predicted output values obtained, and the power generation control system detects and outputs a load condition maximizing the output value by repeating the process while gradually narrowing a width of the load range including the output load condition.
