Junction box protects the electrical connections of the solar panel from environmental conditions. Wire leads connecting the panel to the string and bypass diodes are located inside the junction box. The leads make the panel easy to connect in the string during the system's installation process.
Mainly used for connecting solar panels and inverters
Adopting high-quality tinned pure copper: The copper core adopts surface tinning technology, which has characteristics such as oxidation resistance, rust resistance, and good conductivity. The internal use of 99.98% pure copper has low resistance and can reduce the power loss during current conduction.
Environmentally friendly flame-retardant insulation material: the cable adopts radiation cross-linked Low smoke zero halogen flame-retardant environment-friendly polyolefin (XLPO), which is flame retardant, high and low temperature resistant, ultraviolet resistant, corrosion resistant, and has a long service life.
What is solar EVA film?
EVA is ethylene vinyl acetate, a material that has good radiation transmission and low degradability to sunlight. This is a thermoplastic polymer, which is used in solar modules as an encapsulating agent since, by applying heat to the assembly, it forms a sealing and insulating film around the solar cells.
Aluminum frame is one of the important auxiliary materials of photovoltaic modules. It is used to protect the glass edge, strengthen the sealing performance of photovoltaic modules and improve the overall mechanical strength of photovoltaic modules, which is convenient for the installation and transportation of photovoltaic modules. Photovoltaic module frames are generally made of 6063 or 6005 aluminum profiles, which have the characteristics of light weight, strong corrosion resistance, easy molding, high strength, easy cutting and processing, and recyclability. Currently, the market share of aluminum frames is 96%.
