According to the China Popular Science Network, we learned that Class A fire-resistant photovoltaic modules refer to photovoltaic modules that can meet the requirements of relevant national fire protection standards. Here are some common Class A fire-resistant photovoltaic modules:
1. High temperature solar cell modules: These photovoltaic modules can exhibit good flame retardant performance in high temperature environments and generally use high temperatures. backsheet materials and flame-retardant type packaging materials.
2. Fire-resistant solar glass: Solar glass with flame-retardant properties can effectively isolate fire and prevent fire from spreading, thereby reducing the risk of fire.
3. Flame-retardant encapsulant: This type of encapsulant can withstand high temperatures, be flame-retardant and flame-retardant, and has good proelectrical insulation properties to ensure that the photovoltaic modules are within the safe operating range.
4. Flame-retardant backsheet material: Photovoltaic modules made of flame-retardant backsheet materials can effectively prevent fires and reduce fire damage to battery components. It is important to note that there are many different brands and models of products on the market, and each manufacturer may use different technologies and materials to provide fire protection properties. Therefore, when selecting Class A fire-resistant photovoltaic modules, it is recommended to refer to the product description and relevant certification standards to ensure that they comply with national fire protection requirements. 'fire.
In general, conversion efficiency, fill factorwise and the appearance of class A is better than those of class B.
The cells are generally divided into monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cells are currently the most rapidly developed type of solar cell. Its structure and production process have been finalized, and its products have been finalized. Widely used in space and ground. This type of solar cell uses high purity monocrystalline silicon rods as raw material.
In order to reduce production costs, solar cells for ground applications now use solar-grade monocrystalline silicon rods, and the material performance indicators have been relaxed. Some can also use the scraps and waste of single crystal silicon materials from semiconductor device processing and then redesign them into timonocrystalline silicon ges specifically for solar cells.
