In the embodiment of the present application, since the mounting groove 103 of the metal roof panel 10 is provided with the first fastening portion 104 only on one side, the intermediate support 11 is correspondingly provided with the second fastening portion 111 only on one side. Consequently, at the in-process of installing metal roof boarding 10 to intermediate support 11, only need with the mounting groove 103 lock joint of roof boarding on intermediate support 11 to with first buckling part 104 from the unilateral lock joint to second buckling part 111 can, the installation degree of difficulty is lower, can also avoid causing damage or deformation to metal roof boarding 10 and intermediate support 11, in order to reduce photovoltaic roofing system's infiltration risk improves photovoltaic roofing system's anti-wind uncovering ability.

Therefore, the installation and construction efficiency of the photovoltaic modules 12 is high, the power generation efficiency is high, the abutted seams among the photovoltaic modules 12 are small, the installation efficiency is high, and the overall power generation capacity of the photovoltaic roofing system is correspondingly high.
As shown in fig. 3, the number of the mounting grooves 103 may be at least two, and the first buckling parts 104 of two adjacent mounting grooves 103 are symmetrically arranged with respect to the bottom plate part 101 therebetween; the quantity of middle support 11 equals with the quantity of mounting groove 103, and a middle support 11 inlays and locates in a mounting groove 103 to, the second buckling parts 111 on the middle support 11 is connected rather than the first buckling parts 104 lock connection in the mounting groove 103 that corresponds.
In a specific application, under the condition that the first buckling parts 104 of two adjacent mounting grooves 103 are symmetrically arranged relative to the bottom plate part 101 therebetween, the buckling directions of two middle supporting seats 11 on two sides of the same bottom plate part 101 can be opposite, and the connection mode is simpler. Therefore, the types of parts used for connecting the intermediate support 11 in the photovoltaic roofing system can be reduced, the parts can be conveniently subjected to standardized management, the stress of the mounting grooves 103 on two sides of the bottom plate part 101 can be uniform, the metal roof panel 10 is further prevented from being damaged, and the connection reliability of the metal roof panel 10 and the intermediate support 11 is improved.
Illustratively, as shown in fig. 3, the first fastening portions 104 of the mounting grooves 103 on the left side of the middle bottom plate 101 are disposed on the left side, and the first fastening portions 104 of the mounting grooves 103 on the right side of the middle bottom plate 101 are disposed on the right side, i.e., the first fastening portions 104 on both sides of the middle bottom plate 101 are symmetrically disposed with respect to the bottom plate 101.

Specifically, under the condition that the first buckling part 104 and the second buckling part 111 both protrude in the first direction and the protruding directions are opposite, the first buckling part 104 and the second buckling part 111 can be buckled by moving or adjusting the metal roof panel 10 and/or the middle support 11 in the first direction, and the buckling manner is simple and easy to implement.
It should be noted that, in practical applications, the protruding directions of the first fastening portion 104 and the second fastening portion 111 may also be set to form a predetermined included angle with the first direction. For example, the preset included angle may be 30 degrees, 50 degrees, 65 degrees, or the like, and the protruding directions of the first fastening portion 104 and the second fastening portion 111 are not particularly limited in the embodiments of the present application.

Because second buckling part 111 sets up on first curb plate 114 or second curb plate 115, can be convenient for second buckling part 111 from the unilateral lock on first buckling part 104, avoid causing damage or deformation to metal roofing board 10 and intermediate support 11, in order to reduce photovoltaic roofing system's infiltration risk improves photovoltaic roofing system's anti-wind ability of taking off.
