[0003] Common photovoltaic tiles all have aluminum alloy profile frames. Due to the material and coloring reasons, they cannot have the same color as the photovoltaic glass. This problem is particularly obvious, especially in the case of reflection. Designers and users have higher and higher requirements for the building appearance. Now, photovoltaic tiles are not only limited to functional requirements, but also need to be further improved in appearance design. Summary of the Invention

The vertical rib edge wrapping is arranged in a fitting manner with the side surface of the photovoltaic tile. A folding surface is arranged on the vertical rib edge wrapping at the top. The folding surface, the vertical rib edge wrapping, and the upper surface of the main body part form a C-shaped frame body for clamping the photovoltaic tile. A water guide groove is arranged on the hidden frame on the left side. When the left and right photovoltaic tiles are installed, the main body part of the hidden frame on the right side is installed in the water guide groove to cover the hidden frame on the left side. The utility model adopts the vertical rib edge wrapping, which not only protects the tempered glass but also helps prevent the double-layer laminated glass from cracking. The hidden frame on the left side is provided with a water guide groove. After the photovoltaic tiles are installed, the hidden frame on the left side is covered, taking into account the overall appearance while the photovoltaic tiles have excellent drainage function. The hidden frame at the top adopts a C-shaped frame body to clamp the double glass up and down to prevent glue opening.

[0009] Further, a water stop rubber strip is arranged on the bottom surface of the hidden frame at the lower side to prevent the upper photovoltaic tile from pressing and breaking the lower photovoltaic tile, and at the same time prevent water from turning up.

[0010] Further, the water-stop rubber strip is shorter than the hidden border at the lower side, and there is a gap at the hidden border on the right side. There is a 20-mm break at the right end of the lower border for draining water from the border of the right photovoltaic tile.

[0011] Further, the hidden borders on the left side, right side, and lower side are bonded to the photovoltaic tiles with silicone sealant, and at the same time, the borders are designed with a wider width to increase the bonding area.
