Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, and more particularly to an automatic drainage device for photovoltaic modules. Background Art

[0002] After the existing photovoltaic modules are installed, in order to obtain long-term illumination and achieve the maximum power generation benefit, the modules are installed at a certain inclination angle. When there is precipitation outdoors, water will flow from high to low along the glass surface. Since there are aluminum frames around the modules, rainwater will accumulate on the glass side of the aluminum frame at the lowest point and cannot be drained in time. The rainwater can only evaporate by the sun, which will cause soil residues to be generated on the glass surface for a long time. These residues will block the solar cells and cause the hot spot effect, seriously affecting the power generation efficiency. Summary of the Utility Model
