Hard core measurement! How big is the domestic photovoltaic connector market?
2023/09/20
After nearly ten years of development, China's photovoltaic industry has become a high-quality strategic emerging industry. CPIA said that at present, China's photovoltaic industry is in the forefront of the world in terms of manufacturing scale, industrialization technology level, application market expansion and industrial system construction.
Of course, China's photovoltaic industry not only has a strong momentum of development at home, but also occupies a place in the overseas new energy market. CPIA said that in 2022, the export amount of only silicon wafers, cells and modules in China's photovoltaic products has reached about US $51.25 billion, an increase of 80.3 percent over the same period last year.
So, as one of the major terminal application markets of the connector, how much market possibility can the connector bring?
Photovoltaic trapped, who will break the game?
2023/09/06
Recently [Photovoltaic Information] WeChat Public Number (PV-info) learned, "It is estimated that the new installed capacity of photovoltaic in the world will be around 350GW this year, and the cumulative installed capacity next year is likely to exceed that of hydropower, will exceed that of natural gas in 2026, and will surpass that of coal as the largest energy source in 2027." On May 23, at the 16th (2023) International Solar Photovoltaic and Smart Energy (Shanghai) Conference of SNEC, Zhu Gongshan, Chairman of GCL Group, made this prediction in his keynote speech.
Analysis of Common Faults of Photovoltaic Module Junction Box
2023/05/29
The junction box has two functions of connection and protection. The connection function is to lead the current generated by the photovoltaic module through the cable and the connector and lead it into the electrical equipment. In order to reduce the loss of the junction box itself, the resistance of the conductive material itself and the contact resistance are required to be as small as possible.
Photovoltaic connector-energy transmitter

Solar energy is an inexhaustible, inexhaustible clean energy, is recognized as an excellent alternative energy, therefore, the development and utilization of solar energy has become a strategic decision for the sustainable development of energy around the world. Among them, solar power generation is an important means of large-scale economic use of solar energy, especially in recent years, solar power generation has been rapid development, but also led to the research, design and manufacture of solar cell modules and related devices in various countries. In order to meet the needs of practical applications, it is necessary to form a solar cell array with multiple solar panels through photovoltaic connectors to obtain the required voltage and current. As one of the components, the photovoltaic connector is also affected by the use environment, use safety, service life and other factors, so the connector is required to have high reliability.
Junction boxes for photovoltaic auxiliary materials: functional and technical requirements
2022/08/09
The main function of the junction box is to connect the internal solar cell circuit of the component with the external circuit through the positive and negative cables of the junction box to transmit the electric energy. The junction box is glued to the back plate of the component through silicone.
Bypass diodes are provided in the junction box to protect the battery string. Junction box design requirements are very high, involving electrical design, mechanical design and materials science and other fields of technology.
Photovoltaic junction box: product iteration continues, fast-growing high-business track.
2021/11/12
As a connecting device, the photovoltaic junction box is one of the key auxiliary materials for the production of photovoltaic modules. It mainly has two functions: one is to connect, connect the photovoltaic module and the load, and draw the current generated by the module and generate power; the other is to protect, When the hot spot effect occurs in the component, it plays an automatic protection role.
