PURPOSE:To select the connections between arbitrary terminals in correspondence with desired outputs, by dividing all solar battery elements into at least four series-connected unit structures, and collecting the positive and negative output terminals, which are taken out of both ends, into a terminal box, which is provided at the back surface of a light receiving surface. CONSTITUTION:For example, 36 solar battery elements 2, 2... are arranged in an attaching frame 1, with a light receiving surfaces facing sunlight, and sealed by weather resisting sealing agent in an airtight manner. Of the 36 elements, 9 elements are grouped into one unit, and the elements are connected in series by using inner connecting wires 3. Thus a unit series-connected structure is formed. From both ends of each of the four unit series-connected structures S1, S2, S3 and S4, positive and negative output terminals 1P and 1N, 2P and 2N, 3P and 3N, and 4P and 4N are taken out and collected in a terminal box 4, which is provided at the back surface of the light receiving surface. The required output voltage can be obtained only by changing the connections of bus bars. Matching with the required voltage can be obtained under the nominal output voltage of the solar battery module. Therefore, the solar battery module, in which applicable voltage is broad and the selection and change of the voltages are easy, can be obtained without sacrificing the area efficiency. |
