the below of the lower frame of every group dual-glass photovoltaic board 111 is provided with a convex mirror 3, and every convex mirror 3 all inclines to set up for the convex mirror 3 of the lower frame of every group dual-glass photovoltaic board 111 faces the back that corresponds dual-glass photovoltaic board 111 among the adjacent one row of dual-glass photovoltaic array 1, is used for reflecting sunshine to this back that corresponds dual-glass photovoltaic board 111, and a side view of this photovoltaic power generation device is shown as figure 2.
Each group of double-glass photovoltaic panels 111 is formed by connecting a plurality of double-glass photovoltaic modules in series and in parallel, and the number of the double-glass photovoltaic modules contained in each group of double-glass photovoltaic panels 111 is determined according to actual conditions; in addition, as is well known to those skilled in the art, the dual glass photovoltaic array 1 is arranged in parallel front and back, and is generally arranged at equal intervals, and the interval between the arrays is selected according to the actual situation of setting the photovoltaic power generation device, so that the shadows of the arrays do not shield each other in a one-day period.
Further, as a common arrangement mode of the photovoltaic power generation device, the inclination angles of each group of double-glass photovoltaic panels 111 are the same, that is, the included angles between the plane where each group of double-glass photovoltaic panels 111 is located and the horizontal plane are the same. And the inclination angle of the double-glass photovoltaic panel 111 is also determined according to actual conditions, and the inclination angle is the corresponding optimal inclination angle when the photovoltaic power generation device generates the maximum power in one year. The optimal tilt angle is related to the geographical latitude of the location where the photovoltaic power generation device is located, and when the latitude is higher, the corresponding optimal tilt angle is also larger. Generally, the inclination angle of each set of dual-glass photovoltaic panel 111 can be set to 33 °, which means that the inclination angle of each set of dual-glass photovoltaic sub-array 11 and each row of dual-glass photovoltaic array 1 is 33 °.

As another alternative fixing manner of the convex mirror, each convex mirror 3 may also be fixed to the fixing surface of the photovoltaic bracket 2 through another mounting component, and when the photovoltaic power generation apparatus is disposed on the ground, the fixing surface of the photovoltaic bracket 2 is the ground, and of course, the fixing surface may also be a roof. If the fixing surface of the photovoltaic bracket 2 is fixed, the fixing surface needs to be treated to a certain degree, so that the fixing is firm.
In addition, no matter which setting mode of the convex mirror 3 is, the used mounting pieces support the convex mirror 3 to rotate and adjust the included angle between the convex mirror 3 and the horizontal plane through the corresponding mounting pieces, so that the angle of the convex mirror 3 can be conveniently adjusted to be the optimal angle according to the actual situation, and the convex mirror 3 can better reflect sunlight to the back of the double-glass photovoltaic panel 111; therefore, the photovoltaic power generation device has stronger universality and can be conveniently applied to wide places.
