PROBLEM TO BE SOLVED: To obtain a solar battery unit which ensures easy maintenance work by installing it on a roof material and external panel and then supplying power generated by solar power generation method. SOLUTION: In a solar battery unit 1, a solar battery module 2 having a predetermined capability of solar power generation is fixed to a frame 3, a reverse current preventing circuit, a secondary battery and/or electric double- layered battery and a local controller accommodating a box 4 which accommodates a power controller, adding an over-charging control circuit and over-discharge control circuit as required are mounted at the rear side of the solar battery module and a lead wire 5 is also provided. Then this solar battery unit 1 is installed on a roof material and to an external panel, and the solar battery units are mutually connected to form a stricture so as to ensure the supply of solar power generation power and easy maintenance through easy disassembling and moving. |
