PROBLEM TO BE SOLVED: To optimize the number of lead battery cells and the number of amorphous solar battery cells. SOLUTION: A solar power system has a solar battery 1 which is composed of S solar battery cells 11, 12,...1S Which are connected in series to each other and have photoelectric conversion layers which are composed of layered three photoelectric conversion layers respectively, a battery 3 composed of B lead single battery cells 31, 32,...3B which are connected in series to each other and a charge controller 2 which has a reverse current blocking means. The ratio S/B of the number S of the solar battery cells to the number B of the lead battery cells is to be 10/6-12/6. |
