Trina Storage, a leading provider of energy storage solutions, has released independently verified operational data for its Elementa Series Battery Energy Storage System (BESS) from a 150MW utility-scale agrivoltaic project. The performance evaluation, conducted by globally recognized third-party authorities UL Solutions and the China Quality Certification Center (CQC), confirms the system's robust efficiency and durability after more than a year of continuous operation within a solar-plus-storage hybrid renewable energy installation.

Chen Chi, product manager in the Energy and Industrial Automation group at UL Solutions, highlighted the rigorous assessment, stating, “Over the course of more than a year, UL Solutions conducted a rigorous evaluation of the Feicheng project based on strict performance standards. The system has consistently shown optimal efficiency and cycle life, and low auxiliary power consumption throughout the monitoring period. These outcomes indicate a solid level of technical integration and reliable performance under real-world conditions.” This independent validation provides crucial assurance for investors and developers in the rapidly expanding energy storage market.

The Elementa Series, which powers the project, features Trina Storage’s proprietary in-house battery cells and incorporates a smart thermal management system designed to maintain cell temperature variation within a narrow 3°C range. This precise control, combined with an impressively low auxiliary power consumption of 1.8%, contributes to an approximate 30% reduction in energy loss compared to conventional systems. These efficiencies translate into an estimated 200,000 kWh of additional electricity annually, significantly boosting overall project output and economic returns.

Operational results demonstrate the Trina Solar Elementa Series system consistently achieved 95.2% DC-side efficiency and an impressive 87.1% system-level round-trip efficiency, positioning it among the most efficient large-scale energy storage systems currently deployed. Furthermore, after over a year in service, the system retains 98% of its usable capacity, indicating minimal degradation and strong cycle performance. This long-term reliability is projected to support a 15–20% reduction in the Levelized Cost of Storage (LCOS) compared to industry averages, enhancing project bankability and accelerating investment.

Shawn Deng, Head of Global Product & System Integration at Trina Storage, emphasized the company's commitment to transparency and performance. “We’re proud to see our technology delivering real value under field conditions,” Deng stated. “From Cell-to-AC capability to third-party validation, our goal is to build trust through performance. We’ll continue working with global partners to test next-generation systems in diverse environments and provide transparent, data-driven benchmarks for the industry.” This commitment to verifiable performance is critical for de-risking large-scale renewable energy projects and fostering broader market adoption of advanced BESS technologies.
