A reliable, long lasting solar battery system capable of collecting and storing long-term data on charge and discharge is provided. The system includes a solar battery having a charge control means, and a storage battery, wherein the charging volume of the storage battery is detected by a charge quantity detecting means. Further, a discharge quantity of the storage battery is detected by a discharge quantity 3c. The detected analog signal is sent through an external interface means to an operation and decision means. An operation and decision means controls a discharge quantity control device, wherein the detected signal, as well as other signals, are processed, together with appropriate various command signals sent by a storage means in accordance with a load or loads, and are outputted to a discharge control means. Further, data on present and past command signals, including the result of past control, are stored in order of time into the storage means. A control signal for controlling the output discharge quantity controls the discharge output means in accordance with the charge quantity of the discharge control means, and the discharge output means supplies the needed electric power to a load.
