kolhis High Diffuse Reflectance Water Base Coating for Solar Glass

Based on the recent development of renewable energy utilization technology, in addition to centralized photovoltaic power plants, distributed photovoltaic power generation systems represented by building-integrated photo- voltaic systems ( BIPV ) are frequently employed for power supply. Therefore, in the architectural design, the double-glass photovoltaic module used in the integrated photovoltaic building system puts forward a higher load-bearing capa- city requirement and the corresponding simplified method of carrying capacity check.

BIPV systems are an important part of photovoltaic applications . Photovoltaic modules are designed to be combined with buildings as building components to reduce the cost of building materials while providing additional power for buildings. Therefore, BIPV systems can meet the requirements for green building energy savings, emission reduction, and economic savings and are important development goals for photovoltaic applications.

In the BIPV system, photovoltaic modules with different packaging materials can be used for different applications. For example, ordinary single-glass photovoltaic modules are usually used on opaque roofs . However, in actual engineering, the photovoltaic modules used in BIPV systems must not only provide electricity for building use but also meet lighting and safety requirements .

Therefore, BIPV systems often use photovoltaic modules called double-glass photovoltaic modules . Compared with traditional single-glass photovoltaic modules used in centralized photovoltaic power stations, double-glazed photovoltaic modules have better light transmittance. However, BIPV systems can use double-sided double-glazed photovoltaic modules, which will provide more electricity than single-sided double-glazed photovoltaic modules.

As the name suggests, it refers to a photovoltaic cell module formed by two pieces of glass and solar cells composed of a composite layer, and the cells are connected in series and connected in parallel to the lead ends. In recent years, double sided glass solar panels are like riding on a rocket, and their popularity is soaring. Why are they so popular?

Advantages of double sided solar panels:

It has a higher life cycle power generation, which is 21% higher than ordinary components.

The abrasion resistance of the glass is very good, which also solves the problem of wind and sand resistance of the components in the field. Where there is heavy wind and sand, the wear resistance of double-glass components is obvious.

The warranty for ordinary solar panels is 25 years, and the warranty for a double-glass photovoltaic solar panel is 30 years.

The insulation of the glass is better than that of the backplane, which enables the double-glass module to meet higher system voltage, so as to save the system cost of the entire power station.

The attenuation of traditional solar panels is about 0.7%, and the attenuation of double-glass solar panels is 0.5%.

The high diffuse reflective coating, which is a water-based high reflective coating applied to the back plate of a photovoltaic double glass module, is characterized by its toughened glass coating. This coating is created through instant tempering at high temperatures of 650 °C – 720 °C, followed by instant cooling to meld the glass pigment and the glass together, ensuring color adhesion and durability. The glass structure, fortified with good coloration, exhibits high strength, robust resistance to atmospheric corrosion, and excellent coverage.

With a reflectivity exceeding 83% = 1%, the high reflective coating significantly enhances the reflectivity of the adhesive film and the back panel. Consequently, this improves the power generation efficiency of the solar cell module, potentially achieving a module conversion efficiency of up to 3%.

The glaze layer demonstrates outstanding reflectivity performance. The product has obtained various performance certifications from the National Testing Center, SGS environmental protection certification, and general cargo transportation certification. This environmentally friendly, pollution-free product boasts superior comprehensive performance, remarkable low shrinkage, and high reflectivity, all of which contribute effectively to the increased power generation efficiency of the component.
