Key points for improvement of junction box quality: As a supporting product of photovoltaic modules, solar junction box the cost of photovoltaic junction boxes is less than one-tenth of the cost of batteries, but it is an important component that determines whether photovoltaic modules can eventually work normally. Therefore, solar junction box the quality of the junction box should be improved from the following aspects:
The box body and the box cover are separated, and the design is sealed by a sealing ring, solar junction box and the box body and the box cover are crimped into an integrated sealing process to strengthen the sealing and sealing strength of the entire junction box structure. According to the current needs of component certification, manufacturing, solar junction box and use, it is recommended to reserve an expansion connector in the junction box; the maximum working current of the junction box can be changed at any time by assembling diodes of different specifications;solar junction box the sealant and sealant should be kept in the junction box assembly according to the component production process. Two installation methods of potting glue.
Consider setting up an air guide valve on the cover of the junction box to dissipate the heat inside the box, solar junction box or use thin metal terminals inside the junction box to add heat sinks to achieve the effect of cooling. Through a series of tests, we will study the compatibility of different types of silica gel and different backplane materials, solar junction box and provide photovoltaic module manufacturers with a complete set of solutions for the installation, solar junction box use and matching of junction boxes.
The development direction of the junction box: The junction box plays a very important role in the solar cell module. With the application of the entire photovoltaic market, solar junction box the major junction box manufacturers are working hard in the direction of providing higher quality junction boxes, solar junction box such as designing high-quality junction boxes. Junction box with rated current, high water resistance, excellent heat dissipation, low resistance, solar junction box etc.
At the same time, with the continuous development of photovoltaic intelligent monitoring, solar junction box smart junction boxes are also the general trend of the future development of junction boxes. This intelligent junction box can monitor the operating status of each component at any time, solar junction box and has the function of tracking the maximum output point of the component, solar junction box which can maximize the power generation and meet the requirements of component-level monitoring.
