The support portion 12 has a cavity 120 extending along the length direction of the frame. A filler 2 is disposed in the cavity 120. The bottom of the support portion 12 has a connecting portion 13 extending towards one side of the frame. An L-shaped reinforcing member 3 is provided on the inner side of the support portion 12 and the connecting portion 13 and / or on the outer side of the support portion 12 and the connecting portion 13.

[0028] By arranging a filler 2 inside the cavity 100 of the frame and setting an L-shaped reinforcing member 3 on the inner side of the bearing portion 12 and the connecting portion 13 and / or on the outer side of the bearing portion 12 and the connecting portion 13, the load-bearing capacity, bending resistance and mechanical strength of the frame can be enhanced, making the photovoltaic module less susceptible to the influence of the external environment after installation and more durable.

[0029] In a preferred embodiment, L-shaped reinforcing members 3 are provided on the inner side of the support portion 12 and the connecting portion 13 and on the outer side of the support portion 12 and the connecting portion 13.

[0030] In some embodiments, an L-shaped groove is provided on the inner side of the support portion 12 and the connecting portion 13 and / or on the outer side of the support portion 12 and the connecting portion 13. The L-shaped groove extends from the top of the support portion 12 to the end of the connecting portion 13. The depth of the groove is 0.1 mm to 0.3 mm. The L-shaped reinforcing member 3 is disposed in the L-shaped groove.

[0031] In some embodiments, the L-shaped reinforcing member 3 is disposed in the L-shaped groove by hot rolling composite, explosive composite, or friction stir welding composite. Preferably, during the extrusion of the aluminum profile, the L-shaped reinforcing member 3 is composited with the bearing portion 13 and the connecting portion 13.

[0032] In some embodiments, the connecting part 13 and the L-shaped reinforcing member 3 are provided with multiple mounting holes along the length direction, and the frame is fixed to a fixed object such as a wall or roof by connecting members such as bolts passing through the mounting holes.

[0033] In some embodiments, the filler 2 is a rectangular structure composed of a first filler 21 and a second filler 22, and the first filler 21 and the second filler 22 are L-shaped plates.

[0034] In some embodiments, the support portion 12 is made of aluminum alloy because aluminum alloy has advantages such as strong corrosion resistance, low density, high strength, good heat dissipation, easy processing, and good recyclability. Furthermore, the filler 2 and the L-shaped reinforcement 3 are made of steel, aluminum alloy, or polymer, etc.

[0035] Preferably, the first filler 21, the second filler 22, and the L-shaped reinforcing member 3 are all made of L-shaped steel sheets with a thickness of 0.1 mm to 0.3 mm.

[0036] In some embodiments, the top wall thickness of the support portion 12 is 0.7mm to 0.9mm, and the side wall thickness of the support portion 12 is 0.7mm to 0.9mm. Compared with traditional photovoltaic frames, since the support portion 12 of this invention is made of aluminum profile, and the filler 2 and L-shaped reinforcing member 3 are both L-shaped steel sheets, the total thickness of the filler 2, support portion 12, and L-shaped reinforcing member 3 of this invention is reduced to 0.8mm to 1.2mm, thereby reducing the material consumption of photovoltaic modules and lowering costs.

[0037] In some embodiments, the top and bottom of the filler 21 are provided with a plurality of protrusions 23.

[0038] In some embodiments, the frame also includes a mounting portion for encapsulating the laminate. The mounting portion includes an extension 110 that extends upward from the outer top of the support portion 12 and along the length of the support portion 12.

The edge of the laminate is fixed to the mounting platform by adhesive.

[0039] In some embodiments, the mounting part has an overflow groove 112 on the surface of the mounting platform 111. When the frame is assembled, the adhesive is squeezed by the laminate and overflows into the overflow groove 112, thereby forming a uniform adhesive layer between the frame and the laminate.
