The invention discloses a mounting bracket for a solar cell panel, which can improve the power generation capacity of a power generation device without increasing the power generation cost. The mounting bracket comprises a mounting base; a bracket and two supporting plates for fixing the solar cell panel are arranged on the mounting base; the two supporting plates are obliquely arranged on the twosides of the support respectively; the lower ends of the supporting platesare fixed on the mounting base through hinge structures; and two ejector rod structures used for supporting the supporting plates are arranged on the bracket. In this way, two solar cell panels can be fixed by one mounting bracket and the two solar cell panels are opposite to each other in direction, so that it is ensured that the power generation device can generate power no matter in the morning or in the afternoon, the continuity of the power generation is ensured and the power generation capacity is improved. Meanwhile, the two solar cell panels are fixed on one mounting bracket, so the number of the mounting brackets is reduced, and the cost is greatly reduced. The mounting bracket is suitable for popularization and application in household solar power generation devices.
