PROBLEM TO BE SOLVED: To provide a construction method for a multistage solar cell panel whose power generation efficiency does not depend upon light collection conditions of sunlight.SOLUTION: A supporting column A(1) is provided with metal fittings A(2), metal fittings B(3) and metal fittings C(4). A supporting column B(5) is provided with metal fittings D(6), metal fittings E(7) and metal fittings F(8). Solar panels A(9), B(10) and C(11) are attached to the metal fittings A(2) and D(6). Solar panels D(12), E(13) and F(14) are attached to the metal fittings B(3) and E(7). Solar panels G(15), H(16) and I(17) are attached to the metal fittings C(4) and F(8). A reflecting plate 18 is set on a back of each solar cell panel. A reflecting sheet 19 is set on earth surface portion around the columns A(1) and B(5). |
