[0023] The upper inner arc segment 3 has an upper concave arc groove 3-1 opening toward the inner side of the frame, and the lower inner arc segment 4 has a lower concave arc groove 4-1 opening toward the inner side of the frame; a channel 6 for dissipating heat in summer and keeping warm in winter is formed between the inner wall of the outer arc segment 2 and the outer walls of the upper inner arc segment 3 and the lower inner arc segment 4.

[0024] like Figure 4 As shown, an installation structure of the above-mentioned photovoltaic frame uses fasteners to fasten and connect two adjacent frames installed with photovoltaic laminates 1, and the two ends of the fasteners are respectively clamped and fixed with the upper inner arc segment 3 and the lower inner arc segment 4. A mounting component 7 is provided at the bottom of the fastener, and the fastener is fastened to the mounting component 7. The mounting component 7 fixes the photovoltaic frame installed with the photovoltaic laminate 1 on components such as color steel tiles or beams.

[0025] Specifically, if Figure 3 As shown, the fastener comprises an upper fixing rod 8 and a lower fixing rod 9 which are clamped together, the upper fixing rod 8 has an upper arc-shaped bent rod 8-1 at both ends which is clamped into the upper concave arc groove 3-1, and the lower fixing rod 9 has a lower arc-shaped bent rod 9-1 at both ends which is clamped into the lower concave arc groove 4-1.

[0027] The mounting member 7 is embedded in the lower rectangular groove 9 - 3 of the lower fixing rod 9 , and the upper boss 8 - 2 is fixedly connected to the mounting member 7 by bolts.

[0028] During installation, first, the photovoltaic laminate 1 is correspondingly embedded in the grooves 5 of the four special-shaped frames to form a set of photovoltaic module units, and then the other assembled photovoltaic module unit is placed on the left side, and the upper arc-shaped bent rod 8-1 at the right end of the upper fixing rod 8 is inserted into the upper concave arc groove 3-1 of the upper inner arc segment 3 of the right special-shaped frame, and the lower arc-shaped bent rod 9-1 at the right end of the lower fixing rod 9 is inserted into the lower concave arc groove 4-1 of the lower inner arc segment 4 of the right special-shaped frame.
