Charge control device, charge control method, and photovoltaic power generation system

摘要

In order to charge a battery more efficiently, a solar power generation system (11) comprises solar power generation panels (12), a battery (13), and a power controller (14). A control unit (25) of the power controller (14) starts charging the battery (13) with power generated by the solar power generation panels (12) when it is has been predicted that there will be an increase in solar insolation reaching the solar power generation panels (12) on the basis of information for predicting the weather acquired by a communication unit (24) via a network. The present invention can be applied to solar generation systems having solar power generation panels and batteries, for example.
