Example 1:

referring to fig. 1 to 6 and 13, fig. 1 is a schematic structural diagram after installation, and fig. 2 is a schematic structural diagram of the photovoltaic panel bracket; fig. 3 is a schematic structural view of a hanging rod, and fig. 4 is a schematic structural view of a telescopic structure; fig. 5 is a schematic structural view of a second square tube; fig. 6 is a schematic structural view of a first square tube; fig. 13 is a schematic structural view of a balcony.

As shown in fig. 1 and fig. 2, the photovoltaic panel bracket is mainly used for supporting the photovoltaic panel 1, and the application is not particularly limited because the use scene of the photovoltaic panel 1 can be on a balcony or on the ground or on the roof; in this embodiment, taking a balcony as an example, as shown in fig. 13, the balcony is mainly composed of a base 11, a vertical rod 10 and a fixing rod 9, and a photovoltaic panel bracket is generally fixed with the fixing rod 9 and the vertical rod 10. Because the photovoltaic panel 1 is heavy when the photovoltaic panel bracket is hung outside the balcony, the weight is about 30-100 jin; typically 20-30 kg; especially in severe weather conditions such as high winds, the photovoltaic panel support needs to fix the photovoltaic panel 1 stably and reliably outside the balcony in order to avoid falling or shaking of the photovoltaic panel 1.

Further, because the photovoltaic panel support and the photovoltaic panel 1 are synchronously hung outside the balcony, under the limitation of the self strength of the balcony, if the weight of the photovoltaic panel support is too large, the balcony is easy to deform in the long-term use process, and in order to avoid potential safety hazards caused by the overweight of the photovoltaic panel support to the balcony, the self weight of the photovoltaic panel support is not too heavy. Moreover, for the photovoltaic panel 1, the time and intensity of the photovoltaic panel 1 receiving the sun illumination can influence the power generation efficiency, and the power generation efficiency of the photovoltaic panel 1 is highest when the sunlight is directly irradiated, so that when the photovoltaic panel 1 is fixed by using the photovoltaic panel bracket in different areas or at different times, the angle between the photovoltaic panel 1 and a balcony is required to be changed by the photovoltaic panel bracket to adjust the time and the intensity of the photovoltaic panel 1 receiving the sun illumination, thereby improving the power generation efficiency of the photovoltaic panel 1 and the applicability of different areas.

It is therefore very important for the photovoltaic panel support to be suspended outside the balcony for a stable support of the photovoltaic panel 1.
