In addition, since one of the right frame 12 and the left frame 11, and one of the upper frame and the lower frame is provided with an extension edge 5, the extension edge 5 is used to cover the rubber strip 4 between the adjacent photovoltaic modules 1 to protect the rubber strip 4, slow down the aging of the rubber strip 4, and prevent the rubber strip 4 from falling out due to thermal expansion and contraction. The extension edge 5 can also reduce the amount of water entering the gap between the photovoltaic modules 1. The device makes a minor improvement to the frame of the photovoltaic module 1, so that the frame is combined with the rubber strip 4, so as to achieve the purpose of reliable waterproofing of the photovoltaic sun room while being easy to install and maintain.

[0044] In summary, the photovoltaic sun room waterproof structure provided by the utility model can make the waterproof performance of the photovoltaic sun room more reliable, and at the same time make the photovoltaic sun room easy to install and maintain.

[0045] In one embodiment, the adhesive strip 4 is attached to the left side of the left frame 11, the right side of the right frame 12, the upper side of the upper frame, and the lower side of the lower frame. That is, the adhesive strip 4 can be attached to the frame of the photovoltaic module 1 to achieve preliminary positioning of the adhesive strip 4.
