Selection of Bypass Diodes

The diode in the photovoltaic junction box is used as a bypass diode to prevent the hot spot effect and protect the components. The selection of bypass diodes mainly needs to follow the following principles: 1. The withstand voltage capacity is twice the maximum reverse working voltage; 2. The current capacity is twice the maximum reverse working current; 3. The junction temperature should be higher than

How to choose the model and specification of the junction box

The photovoltaic junction box is a kind of connector of the solar cell module. Its primary function is to export the electric energy generated by the solar cell module through the cable. Due to the particularity of the use of solar cells and their expensive value, photovoltaic junction boxes must be specially designed to meet the use requirements of solar cell modules. In the photovoltaic power generation system, if

Precautions for junction box installation

The junction box should be tested before use. The main items are appearance, sealing, fire resistance level, whether the diode is qualified, etc. The test is as follows: 1. Appearance: size, with or without defects, operate by the incoming inspection work instructions 2. Mechanical properties: the tension between guide and bus bar; clamping force at diode angle; tension between wire and junction box; tension

How to install a solar junction box

The solar junction box is essential because it connects your solar panel to the outside world and protects your connections from outside the solar panel. Its second purpose is to give you an easy way to connect and disconnect solar panels for maintenance or repair or create a series of solar panels (solar arrays) together. Additionally, it adds an overall professional look to the entire panel. Before installation,

Application FAQ

1. Electrical performance The electrical properties of the junction box mainly include parameters such as working voltage, working current, and resistance. Therefore, to measure whether a junction box is qualified. 2. Working voltage When the reverse voltage applied across the diode reaches a specific value, the tube will be broken down, and the unidirectional conductivity will be lost. Therefore, the maximum re

How to test the performance of the solar connector

Solar Connectors are transmitters of energy and carriers of electricity. When power is transmitted, there is bound to be a loss. For connector manufacturers, the biggest test is how to achieve safe and stable transmission with minimal energy loss. The reliability of the connector considers the following factors: 1. Materials for connector product design and product manufacturing; 2. Operating environment; 3.

How to choose the model and specification of the connector

As an integral part of solar cell modules, photovoltaic connectors should be used in harsh environmental climate conditions with significant contrast changes. Although the ecological climate in different parts of the world is different, and the environmental temperature in the same area varies greatly, the impact of the environmental environment on materials and their products. To sum up, there are four significan

Precautions for connector construction

According to the "Review and Analysis of Factors Affecting Photovoltaic Power Generation" report released by the "Solar Bankability" project team of the EU Horizon2020 plan, among the power generation revenue losses caused by the risk of failure of the TOP20 technology in the power station, connector damage and burnout ranked first. 2 digits. How to install photovoltaic connectors correctly is

Application FAQ

The connector is tiny, needs to be used in many links, the cost is small, and many companies produce connectors. For this reason, many people ignore the product of the connector, but it is often easy to cause subsequent power stations because of this inattentiveness. Failures occur frequently. common problem: (1) Contact resistance increases The contact resistance of the connector directly affects the power gene
