Flat solar panel with fine-adjustable inclination angle

The invention discloses a flat solar panel with a fine-adjustable inclination angle. The solar panel is mainly composed of a base, a heat collection plate and a fixed support. The base is a square steel plate fixedly and perpendicularly arranged with a wall, the heat collection plate is fixedly connected with the base through fixed connection holes, fixed adjustment holes are formed in the heat collection plate, and the fixed support is formed by a left triangular support and a right triangular support. One ends of adjusting rods are fixed on the wall, and the other ends of the adjusting rods are connected with the fixed-adjustment holes of the heat collection plate. According to the flat solar panel, the solar height angle in winter is small, and fine adjustments at the outermost ends of the adjusting rods are used to enable the distance from the upper end of the heat collection plate to the rear wall to be largest; and in summer, the solar height angle is large, and fine adjustments at the tail ends of the
