The invention discloses a fine angle adjustment device for a solar photovoltaic panel. The fine angle adjustment device comprises an adjustable fixing seat, and an elastic speed regulating mechanism and an angle adjusting mechanism which are arranged on the adjustable fixing seat, wherein a bearing plate is fixedly arranged on the adjustable fixing seat; a solar photovoltaic panel is fixedly arranged on the surface of the bearing plate; the bottom surface of the bearing plate is connected with the top ends of the elastic speed regulating mechanism and the angle adjusting mechanism. Due to matched use of the angle adjusting device and the elastic speed regulating device, the angle of the solar photovoltaic panel can be directly adjusted by a fine adjustment device in the angle adjusting process, the whole device does not need to be moved, the speed adjustment is controllable, fine angle adjustment can be further realized, and the accuracy of the solar photovoltaic panel fixing angle isrealized.
