LONGi and NIO launch integrated PV and charging station as blueprint for green mobility

LONGi and the smart electric vehicle brand NIO have officially launched a joint "PV-Storage-Charging-Swapping" integrated project in Jiaxing. The facility, named the "NIO Power Swap Station - Jiaxing LONGi Global Distributed R&D Center," marks a significant step in the cooperation between the two companies. It introduces an energy solution that combines solar carports, solar walls, and solar noise barriers with an electric vehicle battery swap station. The launch ceremony on 2^nd February 2026 featured the first battery swap performed by a NIO ET9, a high-end, full-size electric executive flagship sedan.

Integrated infrastructure creates closed-loop energy ecosystem and relieves grid pressure

The project combines photovoltaic power generation and energy storage with infrastructure for charging and swapping electric vehicle batteries. It aims to create a closed-loop ecosystem that generates green electricity, stores it safely, and utilizes it efficiently within the transportation sector. The facility incorporates solar panels on the roof of the swap station and parking areas, as well as on surrounding walls and noise barriers. This "roof plus facade" approach ensures a high volume of green power generation. The electricity produced is used directly by the swap station, which helps to alleviate pressure on the local power grid and allows the facility to operate with carbon dioxide emissions approaching zero.

Solar noise barriers offer dual benefits for urban infrastructure development

The project also introduced photovoltaic noise barriers. These structures combine high-efficiency solar modules with road noise reduction technology. While effectively mitigating traffic noise, the barriers continuously generate clean electricity. This application transforms standard public infrastructure into dual-purpose assets that support both environmental protection and energy generation. The approach offers a sustainable model for the upgrade of urban roads and highways, a concept with significant potential for infrastructure projects in densely populated European regions.

LONGi’s Hi-MO X10 and BC technology enable aesthetic and efficient design

The swap station roof utilizes LONGi Hi-MO X10 series modules, which feature Back Contact (BC) technology to ensure high power output. They achieve a conversion efficiency of 24.3%. For the solar walls, the full-black version of the Hi-MO X10 series was selected to maintain an aesthetic, visual appeal that integrates well with the architectural environment. The walls feature a distinctive open design that breaks with traditional construction methods, while the modules offer high resistance to micro-cracking. The solar carports employ a patented clamp-free installation technique with a double-layer waterproof design, ensuring safety during extreme weather conditions while maximizing the use of idle space for energy generation.

Partnership shows potential for decarbonizing transport sector

The collaboration between LONGi and NIO validates the potential of photovoltaics as a sustainable infrastructure element. Lu Yuan, Vice President of LONGi Distributed Business Group and President of the Product and Solution Center, stated that the project represents a practical application of the "Solar for All" concept, integrating green power seamlessly into transportation and architectural scenarios. Qu Yu, President of NIO Energy, noted that the facility serves as a key step in exploring a green transportation energy system where power is generated, stored and used locally. Both companies intend to continue their cooperation to promote the deep integration of "PV+Swapping+Storage" in transportation networks and explore further innovations in grid interaction.
