Compared with the traditional photovoltaic junction box and the silicone-sealed compact photovoltaic junction box, both have their own characteristics, solar junction box but the silicone-sealed compact junction box has more advantages. The main features of the traditional photovoltaic junction box are: the outer shell has strong anti-aging and ultraviolet resistance; it is suitable for use in harsh outdoor environments; solar junction box the PV-JB003-6 junction box is specially designed for solar modules; the internal wiring seat is a circuit board and Two kinds of materials are plastic;solar junction box the power of the junction box can be changed by the welding type of the cable and the assembly of different diodes.
The characteristics of the sealed and compact photovoltaic junction box: It has excellent high and low temperature resistance, fire resistance, solar junction box anti-aging and ultraviolet resistance performance, solar junction box and can meet the long-term use requirements under harsh outdoor environmental conditions;solar junction box excellent waterproof and dustproof effects, using glue filling method Sealed; small shape, ultra-thin design, simple and practical structure, solar junction box and suitable for 90W crystalline silicon photovoltaic modules or thin film photovoltaic modules; the connection of the bus bar and the cable adopts welding and crimping methods, solar junction box and the electrical performance is safe and reliable.
There is no good or bad choice when choosing a junction box, solar junction box you should choose according to your actual needs, which not only meets the needs, solar junction box but also saves resources.
