“Looking ahead, for the energy storage business, the company will uniformly use the ‘LONGi’ brand externally, no longer retaining the ‘Jingkun’ label. In addition, the company will continue to increase investment in R&D innovation, expand advanced capacity such as PCS and system integration, and strengthen digital operations management.” Recently, during the 14th International Energy Storage Summit and Exhibition (ESIE2026), Yu Haifeng, Vice President of LONGi Green Energy (601012.SH), said to reporters from “China Business News” when responding to the coordinated plans following the acquisition of Jingkun Energy.

In November 2025, the Shaanxi Provincial Administration for Market Regulation publicized the equity acquisition case of LONGi Green Energy for Jingkun Energy. In January to February this year, LONGi Green Energy clearly stated in investor interactions that it has completed the acquisition of Jingkun Energy.

As a global leader in photovoltaic modules, LONGi Green Energy ranked first in global module shipments in 2025. Jingkun Energy was established in 2015. It has more than a decade of experience in the energy storage industry. Its cumulative grid-connected capacity exceeds 12GWh, placing it among the top ranks globally on the DC side of energy storage systems and in domestic industrial and commercial energy storage systems.

The deep integration between the two companies is a snapshot of the times when, in the energy storage-and-photovoltaics integration, the industry is moving from concept to reality, and from assembling devices to native integration.

According to Yu Haifeng, in the past two years, customers have frequently asked “When will LONGi deploy energy storage?” In his view, PV-storage integration has become an irreversible mainstream trend in the industry. PV investment and operation customers generally have a rigid need to build energy storage power stations in parallel. Meanwhile, the earlier energy storage market “grew in a rough-and-tumble way,” and system integration was mostly simple patchwork, with prominent pain points. With more than 20 years of accumulated brand trust, LONGi Green Energy hopes to address customers’ core pain points in areas such as technical integration, project delivery, and operations management.

PV and energy storage naturally share the same origin, and the terminal user base overlaps highly. Yu Haifeng said LONGi Green Energy will prioritize serving its existing PV customer group. These users, who highly recognize the LONGi brand, are the most core customer base for its energy storage business. He predicts that in the future, more than 60% of demand in the energy storage market will be deeply integrated with PV application scenarios.

Yu Haifeng revealed that LONGi Green Energy’s founder and Director of the Central Research Institute, Li Zhenqiu, has already driven internally to establish a PV-storage integration technology research institute. The core goal is to achieve deep coupling between PV and storage and pursue the “1+1>2” technical synergy effect. At present, the related technical solutions have been completed; a new PV-storage integration product will be released within the next quarter.

At this exhibition, LONGi Green Energy officially launched its “Full-Stack LONGi LONGi ONE” PV-storage integration strategy. It proposes to build a “sunshine power machine” with both global top-tier efficiency and safety by using an originally integrated fusion technology developed across the full stack. The aim is to completely break the “island effect” that has long existed in PV-storage systems.

In terms of scenario deployment, LONGi Green Energy focuses on two main tracks: large-scale ground energy storage and industrial and commercial energy storage. At this exhibition, it released the large-scale flagship energy storage product OneBank 2.0, the industrial and commercial “Smart Green Electricity” solution Hi‑MO One+ EnergyOne, and the station-level modular flexible deployment product OneMatrix 2.0.

With more than a decade of energy storage technology accumulation from Jingkun Energy as support, LONGi Green Energy has already built a “5S” highly integrated R&D system grounded on five core technologies: iCCS, BMS, PCS, EMS, and TMS, providing technical support for solutions covering the entire domain of green electricity.

“Overall, LONGi hopes to provide terminal users with a complete energy system, information system, and control system, but will not engage in cell manufacturing. We will form deep partnerships with leading cell companies and jointly define the technology direction for cells,” Yu Haifeng emphasized. LONGi Green Energy does not make cells, but will be responsible for the entire chain of the energy storage system.

At this exhibition, LONGi Green Energy first proposed the industry concept of a “single responsible entity.” From PV modules to energy storage systems, from hardware delivery to whole-life-cycle operations and maintenance, customers only need to interface with one entity—LONGi Green Energy—to obtain full-process assurance for power generation, power storage, and power usage. By unifying technical standards, unifying service systems, and unifying the responsible entity, it is possible to clearly trace and efficiently respond to issues across all system links, thereby completely eliminating the shifting of responsibility and management blind spots among manufacturers.

The PV-storage industry has a global nature, and overseas markets are also a key component of LONGi Green Energy’s energy storage strategy.

Yu Haifeng introduced that, relying on the PV marketing and service network covering 120 countries worldwide, as well as Jingkun Energy’s 13GWh global project delivery experience, LONGi Green Energy has launched its “2830 plan”: that is, by the end of 2028, it will set up 30 full-capability localized service centers in major PV-storage integration markets around the world.

“Compared with peers, this global layout will significantly improve efficiency in whole-life-cycle management and speed of service response,” Yu Haifeng said.
