How to repair bright spots on the surface of coated glass after photovoltaic module lamination

Coated glass is precious, I don't know if yours is an automatic line or a manual line.

The manual line is easy to operate, just pay attention to protection, and pad paper protection before lamination; Clean up the weekly loading and cleaning of the car, and pay attention to the lifting and placing of components;

The automatic line is difficult, is it rolling or belted? Exclusion station don't do anything, see if it is generated, and protect if you can do it.

Spot removal is a difficult one, you can find some cleaning agents to try, but in most cases it will hurt the membrane.

Repair method of coated glass:

Method 1: Wipe the scratches with hydrofluoric acid. (Hydrofluoric acid is extremely corrosive, strongly corrosive to metals, glass, and silicon-containing objects.) ）

Method 2: Use the polishing wheel of wool felt and polishing powder to polish the scratched place. (The felt polishing wheel is referred to as the felt wheel, which is divided into two types: roll wool wheel and pure wool wheel.) Specially designed for polishing or repairing abrasions in different materials such as glass, metal, plastic, stone and jewelry. ）

Reflective glass is also known as reflective glass. Coated glass is the coating of one or more layers of metal, alloy or metal compound film on the surface of glass to change the optical properties of the glass to meet a specific requirement. Coated glass can be divided into the following categories according to the different characteristics of the product:

Heat-reflective glass, low-e glass (Low-E), conductive film glass, etc.

The coated glass of photovoltaic modules is seriously reflective, which may affect the efficiency of photovoltaic power generation. In this case, there are several workarounds to consider:

1.Installation of reflector reducer: This kind of equipment is a special material that can form a thin film on the surface of glass, which can effectively reduce reflection and scattering and improve the efficiency of photovoltaic power generation.

2.Replace anti-reflective glass: In view of serious reflection, you can consider replacing anti-reflective glass, which can effectively reduce reflection and scattering, and improve the efficiency of photovoltaic power generation.

3.Cleaning the surface of the coated glass: If the reflection is serious due to dirt or dust on the glass surface, you can consider cleaning the surface of the coated glass reed, which can reduce the reflection and scattering of the liquid and improve the efficiency of photovoltaic power generation.

It should be noted that for the serious problem of reflective glass of photovoltaic module coating, you should find a professional to detect and deal with it. At the same time, regular cleaning and maintenance should also be carried out in daily maintenance to ensure the normal operation of photovoltaic modules.

Glass reflection in photovoltaic modules has a great impact on the efficiency of solar power systems. The severe reflection of the coated glass will cause the module to absorb less solar energy, reducing the power generation capacity of the whole system, which in turn affects its economic and environmental benefits. In order to improve the problem of glass reflection, anti-reflection treatment can be carried out on the glass surface to improve its reflectivity and reduce the reflective intensity, so as to improve the solar energy absorption rate and power generation efficiency.

In addition, the scientific position and angle of the module installation are also important factors affecting the power generation capacity of the system.
