en.Wedoany.com Reported - On June 3, during the 19th International Solar Photovoltaic and Smart Energy (Shanghai) Conference & Exhibition (2026 SNEC), LONGi fully demonstrated the implementation path and core products of its "Full-Stack LONGi ONE" strategy for the first time, proposing a deliverable, verifiable, and responsibility-closed solar-storage integration solution. Li Zhenguo, founder and Chief Technology Officer of LONGi Green Energy, stated: "Cheap electricity, if it cannot be stably fed into the grid and flexibly used, has a ceiling on its value. This is not a technical detail, but a hurdle that the energy transition must overcome." The Full-Stack LONGi solution aims to drive the industry from a multi-supplier patchwork model toward native integration.

At this exhibition, LONGi launched a series of solutions for GWh-level power stations and industrial-commercial areas, including OneBank 2.0, OneMatrix 2.0, Hi-MO ONE, OneNexus, OneSync, and OneOS. According to reports, the round-trip efficiency of the OneBank 2.0 and OneMatrix 2.0 systems reaches 93%, approximately 4 percentage points higher than discrete solutions. The Full-Stack LONGi solution adopts a single-responsibility service model, supporting 99% system online rate. Li Zhenguo interpreted this capability building as "capability extension," emphasizing that LONGi's move into solar-storage is not to build a closed ecosystem, "quite the opposite, it is to better open up."

In terms of technological foundation, LONGi expects cumulative global shipments of BC modules to approach 100GW by the end of 2026. Jiang Dongyu, Vice President of LONGi Green Energy, stated that BC technology achieves a front-side without metal shading through a full back-contact electrode structure, and can serve as a platform technology to overlay with HJT, TOPCon, and other routes. The implementation of the Full-Stack LONGi strategy is accelerating, with LONGi planning to build 30 all-around local service centers in major global solar-storage integration markets by 2028. The first overseas service center has already been established in Madrid, Spain.
