There are two main types of solar junction boxes: ordinary and potting. Ordinary solar junction boxes,solar junction box ordinary junction boxes are sealed with silicone seals,solar junction box and glued junction boxes are filled with two-component silicone for potting. Common junction boxes are used earlier and simple to operate, but the seals are easy to age when they are used for a long time.
The operation of potting the solar junction box is more complicated (two-component silica gel needs to be filled and cured), but the sealing effect is good,solar junction box and it is resistant to aging, which can ensure the long-term effective sealing of the junction box,solar junction box and the price is slightly cheaper. Encapsulated junction boxes were generally used for thin-film modules before, but some manufacturers are also applying them to crystalline silicon modules. In addition to the above two types,solar junction box the other classifications of junction boxes are classified by power and connector,solar junction box and classified by diode operating current.
