[0050] L-shaped notches 422 are symmetrically provided on both sides of the second limiting member 42 , and the photovoltaic components 2 on both sides can be fixed and limited by the L-shaped notches 422 .

[0051] The connecting assembly 31 is suitable for being crimped onto the second sealing member 41 , so that the first connecting mechanism 3 and the second connecting mechanism 4 cooperate with each other to obtain better waterproof sealing capability, while improving the installation stability and avoiding the warping of the second sealing member 41 .

[0052] The installation steps of the system are as follows:

[0053] (1) First, fix the support member 1 to the main body of the steel structure carport with self-tapping screws.

[0054] (2) Stick a 20x2mm foam pad on the bottom of the photovoltaic module 2 (only the part that contacts the support 1 is needed), and then place the photovoltaic module 2 on the support 1 according to the layout plan diagram.

[0055] (3) Insert the connector 43 from the end into the second seal 41, insert it into the top from the bottom of the horizontal installation gap between the two photovoltaic modules 2, and pull down the connector 43 to ensure that the waterproof edge 411 at the top of the second seal 41 is in place with the photovoltaic module 2.

[0056] (4) Then put the first sealing member 313 and the upper pressing member 312 on the decorative cover 314 and press it on the longitudinal frame of the photovoltaic module 2.

[0065] The upper portion of the upper pressing member 312 is connected to the longitudinal waterproof system to ensure that the waterproof system is compacted tightly. The first connecting groove 3121 at the lower portion of the upper pressing member 312 is converted into a bottom mounting structure by a self-locking bolt.

[0066] The second sealing member 41 can be adjusted up and down by pulling the connector 43 so as to be tightly overlapped with the photovoltaic assembly 2 , and converted into a bottom mounting structure through self-shrinking fit with the second limiting member 42 .

[0067] The barbed structures on both sides of the second sealing member 41 form a multi-layer waterproof system with the frame of the photovoltaic module 2 (the figure shows a three-layer waterproof system, which can be selected and changed according to the thickness of the frame of the photovoltaic module 2). The second limiting member 42 is force-integrated with the connector 43 through the fourth connecting groove 421 to ensure that the second sealing member 41 and the frame of the photovoltaic module 2 are tightly overlapped.
