PURPOSE:To realize easy adjustment and maintenance, capable of safe work, by forming a method for tracking the sum light and besides a method for moving the whole frame of a solar cell up and down. CONSTITUTION:Under usual operational conditions, the first driving method 3, with an axis 2 as center, is used for pursuing an azimuth angle, and the second driving method 5 is used for pursuing an elevation angle. With rack mechanism 7 installed in the vertical direction and a geared motor 8 mounted as the third driving method, a pole brace 6 is moved up and down inside a pit 10 made in a concrete foundation part 9. That is, because the pole brace 6 is being raised during ordinary operation, solar light can be collected without possibly nearby obstacle 11 intercepting light. When the pole brace 6 is moved down to have the solar cell frame 1 positioned horizontally by the second driving method 5, installation and adjustment of the solar cell frame 1 can be easily performed with its maintaining and checking work facilitated thereafter. |
