The utility model provides a laying dust photovoltaic module is prevented for planar structure's in surface, includes glass and frame, glass's base is stepped structure, and bench height matches withthe thickness of frame for glass with attach in the frame on glass base for the plane. The utility model discloses an it is based on traditional photovoltaic module structural style improvement, lessto photovoltaic module's cost influence. This photovoltaic module surface is the plane, and there is not any structure that blocks water in the photovoltaic module edge, and dust, rain water pollutiondirt descend freely to scatter in the action of gravity and remove, the structural style of photovoltaic module surfacing easily transports the dimension cleanness. 种表面为平面结构的防积尘光伏组件，包括玻璃和边框，所述玻璃的底边为台阶形结构，台阶高度与边框的厚度匹配，使得玻璃与附加于玻璃底边的边框为平面。本实用新型是基于传统的光伏组件结构形式改良，对光伏组件的成本影响较小。该光伏组件表面为平面，光伏组件边上不存在任何阻水的结构，灰尘、雨水污垢在重力作用下能够自由散落排走；光伏组件表面平整的结构形式易于运维清洁。
