A photovoltaic module waterproof mounting structure

The invention relates to the field of waterproof installation of photovoltaic modules, A photovoltaic module waterproof mounting structure is disclosed, comprises a photovoltaic module, a long-side guide rail and a short-side guide rail for installing the photovoltaic module, wherein the long-side guide rail is installed on a housing bracket, a first water guide groove is arranged on the long-sideguide rail, a plurality of notches are symmetrically arranged along the length direction of the long-side guide rail, and the short-side guide rail is installed at the notches. The water guide grooveis arranged on the guide rail, and after the photovoltaic module is spliced with sealant, the water guide groove is also arranged at the bottom of the sealant, which can play the role of multiple waterproofing. Therefore, the dependency on the construction process quality can be reduced, and at the same time, water leakage caused by aging and poor quality of the sealant can be avoided. 本发明涉及光伏组件防水安装领域，公开了种光伏组件防水安装结构，包括光伏组
