PROBLEM TO BE SOLVED: To minimize the usage of steel products to be used for a solar panel trestle while securing the strength and rigidity of the trestle.SOLUTION: An inclined panel supporting member 2 on which a solar panel 10 is installed at a predetermined angle, and a supporting column 3 on the inclined upper part side and a supporting column 4 on the inclined lower part side for supporting the panel supporting member 2 constitute a vertical planar frame 5. The pair of planar frames 5 are disposed parallel to each other in spaced relation. The pair of planar frames 5 are connected to each other at the positions of the supporting columns 3 and 4 on the upper and lower part sides with only two crossing braces 7a and 7b diagonally mounted between the right and left supporting columns. The supporting columns on the upper and lower part sided, between which a length Lis a range of 0.387 L-0.714 L, are located almost symmetrically away from the front end sides. These members efficiently bear a load to minimize the usage of steel products while securing the strength and rigidity of the trestle. The cross section of the panel supporting member can be efficiently smaller. |
