Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a photovoltaic bracket structure suitable for complex terrains. Background Art

[0002] When installing photovoltaic panels, in addition to directly fitting them close to the roof, some consumers often use photovoltaic brackets to prop up the roof surface and photovoltaic panels in order to make the roof surface passable after the photovoltaic panels are installed. Existing photovoltaic brackets are usually composed of square tubes or U-shaped brackets.

[0003] Since most of the self-built houses in rural areas are not inhabited on the roof, in order to save trouble, people usually do not choose to lay tiles or use fine mortar to level the ground, so that the roof surface will not be too flat. When installing photovoltaic panels on such a roof surface, in order to make the photovoltaic bracket able to support the photovoltaic panels more stably to avoid shaking due to uneven ground, the prior art often uses multiple cement square bricks that are locked together with the photovoltaic bracket by bolts to replace the photovoltaic bracket contacting the roof surface. While reducing the contact area, it also increases the stability of the photovoltaic bracket after the photovoltaic panel is installed by increasing the overall weight of the photovoltaic bracket.

[0004] However, after the actual installation, it was found that since the cement square bricks are only used to level the roof surface they are in contact with, when multiple cement square bricks are used together, the several leveling surfaces may not be in the same plane, resulting in the photovoltaic bracket being placed at an angle that is not straight after being locked with the cement square bricks.

[0005] In view of the above problems, a photovoltaic panel support structure suitable for complex terrain is proposed. Utility Model Content
