LONGi’s expansion into storage complements its existing strengths in PV and hydrogen
LONGi has officially entered the energy storage market, unveiling its LONGi Energy Storage One-Stop Solution, marking a major step in its evolution from a global photovoltaic leader to a full-spectrum “Solar-Storage-Hydrogen” energy provider.
At the launch recently, Dennis She, Vice President of LONGi, introduced the company’s “Stability Triangle” framework, integrating solar, energy storage, and hydrogen. “Solar is the creator of clean energy, energy storage is the stabilizer of the power system, and hydrogen is the regulator that balances it all. The synergy of these three will build a truly widespread, highly resilient, and affordable zero-carbon energy system,” She said.
LONGi’s expansion into storage complements its existing strengths in PV and hydrogen, creating a fully integrated value chain across the “Solar-Storage-Hydrogen” ecosystem.
She highlighted the shifting landscape of energy storage competition. “The current development stage of the energy storage industry is very similar to the early days of solar — confidence-driven rapid growth, but also bringing disorderly competition. The future dimension of competition in energy storage has evolved from ‘having the technology’ to ‘value reliability,’” he said.
“Safety, reliability, and stability are the yardsticks for measuring energy storage solutions and are also the cornerstone for winning the long-term trust of the market and customers.”
To reinforce its commitment to “Ultimate Safety,” LONGi is collaborating with PotisEdge, an energy storage safety expert.
Leveraging a three-pillar technical architecture of “intrinsic safety, active defense, and intelligent early warning,” and PotisEdge’s self-developed “5S” energy storage system with unique BMS and iCCS designs, the partnership boasts a decade-long record of zero thermal runaway incidents across over 12 GWh of storage and battery systems.
LONGi also announced its first Solar-Storage Technology Innovation Center in Europe, designed to provide project consulting, technical training, O&M support, and spare parts services for localized, full-lifecycle solutions.
“Europe's urgent need for energy transition and its mature market mechanisms provide an ideal platform for practicing integrated ‘Solar-Storage-Hydrogen’ solutions,” She said. The company plans to roll out its energy storage solution in key markets including the UK, Germany, Italy, and Spain, helping utilities and power companies build smarter, more efficient clean energy systems.
