The first "Lighthouse + Zero Carbon" factory in the photovoltaic industry

LONGi's Jiaxing Production Base was recognized by the World Economic Forum (WEF) as the photovoltaic industry's first global "Lighthouse Factory," through its advanced applications of automation, Industrial Internet of Things (IIoT), digitalization, big data analytics, and 5th-generation mobile communication technology (5G), demonstrating its leadership in smart manufacturing and digitalization at the pinnacle of global PV industry standards.Building upon its "Lighthouse Factory" intelligent manufacturing framework, LONGi's Jiaxing Production Base further advanced its zero-carbon transformation in 2024. This culminated in its designation as the industry's first "Dual Benchmark" production base certified under the ISO 14068 carbon neutrality standard.

Promoting Carbon Neutrality in 'Lighthouse Factories'

In 2024, the Jiaxing base successfully became LONGi's first zero-carbon factory, adhering to ISO 14068 standards, and is currently the first "Lighthouse + Zero Carbon" factory in the photovoltaic industry.

Lighthouse Factory Enhances Energy Efficiency

A smart energy management system has been deployed, along with the introduction of globally leading intelligent production equipment, including fully automated string welding machines, automated production lines, AI string traceability, and other advanced smart devices and processes. In 2024, the unit product energy consumption at Jiaxing LONGi Solar decreased by 24.6% compared to the previous year.

Promotion of Energy-Saving Renovation Projects

Jiaxing LONGi has conducted transformer energy efficiency upgrades, electrochemical energy storage projects, intelligent control systems for efficient cooling rooms, and EMS system iterations, saving significant amounts of energy consumption for the company. A total of 26 energy-saving projects were implemented in 2024, resulting in an annual energy savings of approximately 13 GWh, equivalent to a reduction of 7,600 tons of carbon emissions.

Accelerating Energy Structure Upgrade

A 17.03 MW photovoltaic power station was built on the roof of the Jiaxing LONGi factory, consuming approximately 16 GWh of electricity in 2024, which accounts for 10.2% of the total electricity consumption and corresponds to a reduction of 9,558 tons of carbon emissions. Additionally, LONGi's first electrochemical energy storage project—the 13.4 MWh electrochemical energy storage demonstration project at Jiaxing LONGi—was successfully connected to the grid in July 2024. Since connecting to the grid, the project has repeatedly responded to the orderly electricity usage requirements of the local energy bureau and grid, receiving high praise from the local government.
