[0002] Photovoltaic panels, also known as solar photovoltaic panels or solar panels, are key devices for converting sunlight into electricity. They are composed of multiple photovoltaic cells, typically made of silicon. The working principle of photovoltaic panels is based on the photovoltaic effect. When sunlight strikes a panel, the energy from photons is absorbed and excites electrons, generating an electric current.

[0003] Rooftop photovoltaic supports are the supporting structures used to mount solar photovoltaic panels on roofs. Their design and installation need to take into account the type, size, slope and tilt angle of the roof to ensure that the photovoltaic panels can be mounted firmly and obtain the best solar energy output.

[0004] In the related art, the installation of photovoltaic panels is generally performed by, but in order to more accurately determine the installation position of the photovoltaic panels, two people are usually required to operate, that is, one person is required to hold the photovoltaic panel by hand to keep it in the correct installation position, and then the other person drives fixing bolts into the four corners of the photovoltaic panel to fix it to the photovoltaic panel bracket. As a result, the manpower required for the installation of the photovoltaic panels is relatively high, which affects the convenience of installation of the photovoltaic panels. Utility Model Content

The limit channel steel 5 is arranged in a concave shape and is arranged parallel to the inclined beam 3. The side wall of the limit channel steel 5 abuts against the photovoltaic panel.

[0033] A locking channel steel 6 is provided on the crossbeam 4 near the rear leg 2 of the two crossbeams 4. The locking channel steel 6 is arranged parallel to the inclined beam 3 and is limited by the limiting channel steel 5. A locking mechanism 7 is provided between the locking channel steel 6 and the crossbeam 4 for pressing the locking channel steel 6 against the limiting channel steel 5 to tighten the photovoltaic panel.

[0034] The locking mechanism 7 includes two first locking blocks 71, each located at the end of the locking channel steel 6. The first locking block 71 is fixedly connected to the crossbeam 4 near the side of the rear leg 2. The first locking block 71 abuts against the end of the locking channel steel 6.

[0035] The locking mechanism 7 also includes an adjustment assembly 72 for adjusting the distance between the locking channel steel 6 and the first locking block 71. The adjustment assembly 72 includes a screw 721, one end of which is fixedly connected to the first locking block 71, and the axis of the screw 721 is parallel to the length direction of the crossbeam 4. The screw 721 passes through the end of the locking channel steel 6 and is slidably connected to the locking channel steel 6. A locking nut 722 is threadedly connected to the screw 721, and the locking nut 722 presses the locking channel steel 6 against the first locking block 71. In this way, the locking channel steel 6 and the first locking block 71 are fixed to each other, and the locking channel steel 6 is fixed to this photovoltaic bracket.
