Abstract

PURPOSE:To make it possible to effectively use power generated by a solar battery by arranging a solar battery for monitoring which has a characteristic similar to a solar battery near the solar battery and detecting the short-circuit current of the solar battery for monitoring. CONSTITUTION:The power produced by the generation of a solar battery 1 is charged in a battery 3 and supplied to each illumination lamp 2a-2n through switches 4a-4n. And a detecting means 6 detects the short circuit current of a solar battery 5 for monitoring, making it output signal 20 through a smoothing circuit 7. This output signal 20 is compared with each standard level 23a-23n by comparison circuits 9a-9n. And each switch 4a-4n is controlled to open or close according to the level of the output signal 20 so as to light the specified illuminating lamps 2a-2n. At this time, the solar battery for monitoring is an independent circuit system, so it is not affected by the large level of the battery. Accordingly, when there is much quantity of solar radiation, the short circuit current also becomes much and the output signal 20 also becomes more as compared with the short-circuit current.
