Tempered glass has very good light transmittance and high hardness. It can adapt to large temperature differences between day and night or bad environments. It is covered on top of the battery to protect the battery.
EVA: Is a hot melt adhesive. The cells are very fragile, so the photovoltaic glass cannot be directly attached to it, and the EVA film is required to play an adhesive role in the middle. EVA film light transmittance is also very well, but after contact with the air it will become yellow and affect the efficiency of power generation.Therefore the technical requirements are very high in the packaging, it is recommended that you find a large enterprise with excellent technology and reliability to install photovoltaic power plants.
Conductive copper strip is made of oxygen-free copper shear straightening, all external surfaces have a hot-plated coating. Electrodes for solar cells used in the production of solar photovoltaic modules are ejected and connected to the cells. It is required to have high welding operability, firmness and flexibility.
Backplane: The backplane also plays a role in protecting the battery, and the backplane must be sealed, insulated, waterproof and resistant to aging. It is used to enhance the aging resistance and corrosion resistance of photovoltaic modules and extend the service life of photovoltaic modules.
TPT: The outer layer is a T film, the middle layer is P film, T and P are bonded with glue. Among them, the T layer is the main layer used as a solar cell packaging material, and its role is weather resistance, UV resistance, aging resistance, no light sensitivity, etc.; The main functions of P-layer are water vapor barrier, electrical insulation, dimensional stability, ease of processing and tear resistance. The middle layer is a polyurethane film with good insulating properties.
Aluminum frame: The solar frame is made of aluminum alloy. Its strength and corrosion resistance are very good. It can play a role in supporting and protecting the entire panel.
Junction box, protect the power generation system of the entire panel, seal and waterproof the line led by the light volt module, and protect the safety of the photovoltaic module system when running. It is equivalent to a current transfer station, and when there is a short circuit in the battery, the junction box will automatically disconnect the short-circuited battery string.
Cells: Solar photovoltaic cells are the core materials of solar photovoltaic modules. It is used to seal the edges of panels and solar frames and junction boxes. The spill groove designed like the solar frame slot is designed to prevent silicone from spilling.
