The aluminum alloy protective laminate plays a certain role in sealing and supporting. The junction box protects the entire power generation system and acts as a current transfer station. If the component is short-circuited, solar panel the junction box automatically disconnects the short-circuit battery string to prevent the entire system from burning. The most important thing in the junction box is the selection of diodes. Depending on the type of cell in the assembly, solar panel the corresponding diodes are also different. Silicone sealing function is used to seal the junction between the component and the aluminum alloy frame, solar panel and the component and the junction box. Some companies use double-sided tape and foam instead of silica gel. Silicone is widely used in China. The process is simple, convenient, easy to operate, solar panel and the cost is very low.
At present, crystalline silicon materials (including polycrystalline silicon and monocrystalline silicon) are the most important photovoltaic materials, solar panel with a market share of more than 90%, solar panel and will remain the mainstream materials for solar cells for a long period of time in the future. The production technology of polysilicon materials has long been in the hands of 10 factories in 7 companies in 3 countries, including the United States, Japan, solar panel and Germany, forming a technology blockade and market monopoly.
