PROBLEM TO BE SOLVED: To provide a trestle for a solar panel, in which an angle between a first extension member extended in the longitudinal direction and a second extension member extended in the lateral direction of a substrate frame for arranging a solar panel can be accurately set.SOLUTION: A substrate frame supported by a bearing member fixed to the ground and used for arranging a solar panel is formed, including: a beam member 4 which is a first extension member extended in the longitudinal direction; and a joist member 5 which is a second extension member extended in the lateral direction. An almost cross-shaped angle defining member 80 is arranged at an intersected portion of the beam member 4 and the joist member 5, and an angle formed by the beam member 4 and the joist member 5 is defined by the angle defining member 80. |
