  • Exploring the Differences Between PV Panel Mount Connectors and PV Connectors

    The main difference between LMC4 Solar connector and panel-mounted LMC4-BD Solar Connector: LMC4 Solar connectors are mainly used for connections between solar panels or between panels and inverters. This type of connection facilitates maintenance and installation.PV panel mount connectors, on the other hand, are designed to be installed in distribution boxes or combiner boxes. This design allows for direct integration with electrical systems, providing a more stable and centralized connection solution for photovoltaic systems.

  • What Should You Consider When Selecting Solar Connectors?

    Solar connectors are widely used in various solar application scenarios, such as solar street lights, solar water heaters, and photovoltaic power stations.

  • Sichuan Launches 1GW PV Project, Paving Way for High-Quality Development of Global Solar Industry

    On March 26, 2025, the 1GW (gigawatt) Xiangcheng Gongzha Photovoltaic Project in Ganzi Tibetan Autonomous Prefecture officially broke ground. As the largest single PV project invested by a Sichuan provincial state-owned enterprise, it not only marks a key milestone in the local new energy sector but also reflects the distinct trend of China’s national solar industry accelerating toward large-scale, intelligent, and high-efficiency development.

  • What are the usage scenarios of DC combiner boxes?

    The working principle of the combiner box mainly involves the connection and protection of circuits.

  • Efficiency Surpasses 30% & Module Power Exceeds 800W: China's PV Industry Enters the "Tandem Era"

    China's photovoltaic (PV) technological innovation witnessed a "boom period" in 2025: in late October, a joint research team from Nanjing University and the National Innovation Institute of Defense Technology achieved a breakthrough in all-perovskite tandem solar cell efficiency, reaching 30.1% and setting a new global record. Three months later, Trina Solar announced that its 210mm large-size perovskite-silicon tandem module had exceeded 800W in power, officially kicking off the industrialization process. This "dual breakthrough"—from basic scientific research to industrial application—marks China's PV industry is transitioning from "leading in scale" to a new stage of "technological dominance".
