Shandong Rizhao Integrated Solar Storage Project Goes Live

The “Integrated Solar Storage and Charging” project, developed through the collaboration of Trina Solar and Zhongke Huachen, has officially commenced operations at the Yijie Tools park in Wulian County, Rizhao City, Shandong Province. This project features the installation of Trina Solar’s top-tier photovoltaic modules on the rooftops of factory buildings, complemented by the Potentia Blue Ocean system, an efficient commercial energy storage cabinet, and electric vehicle charging facilities. The result is a comprehensive energy system that integrates solar power generation, energy storage regulation, and charging services, promoting efficient energy utilization and low-carbon management within the Yijie Tools park. It is becoming a notable example of low-carbon transformation in the industrial sector.

Rooftop Power Generation Matrix: The Hexagonal Warrior of the Power Generation Field

The continuous generation of green electricity at the Yijie Tools factory is powered by Trina Solar’s family of Supreme series products, particularly the Supreme N-type ultra-high power module, which stands out as the “hexagonal warrior” of the photovoltaic industry. This module offers greater installation flexibility and electrical compatibility, excelling in low irradiance performance and addressing challenges in complex scenarios, while achieving higher power generation capacity per watt and lower cost per kilowatt-hour. When paired with Huawei inverters, a highly efficient and stable power generation system is established.

Energy Storage Synergy: Redefining the New Heights of Solar Storage Integration

The Vertex Supreme N-type components, as flagship products of Trina Solar, enhance system generation gains significantly due to their ultra-high conversion efficiency, low degradation characteristics, and high bifaciality. This is combined with Trina’s self-developed 215kWh energy storage system, which achieves efficient integration and intelligent scheduling across the entire chain, effectively addressing electricity fluctuations in commercial and industrial use, reducing electricity costs, and advancing the park’s goals toward becoming a “zero-carbon factory”. Additionally, Trina Solar’s innovative solar storage synergy management system deeply integrates solar and storage technologies, optimizing energy allocation and scheduling through a smart energy platform, providing Yijie Tools with a closed-loop solution for “generation-storage-charging-load” that meets diverse needs in production, storage, and electric vehicle charging.

Calculating Economic Benefits for a Brighter Future

Since 2023, the gap between peak and valley electricity prices has expanded, further highlighting the economic viability of commercial and industrial energy storage as the pace of electricity market reforms accelerates. The willingness of industrial enterprises, particularly energy-intensive manufacturing sectors, to adopt energy storage systems is continuously increasing. The integration of “solar-storage-charging” organically combines clean energy with application scenarios, achieving mutual coordination and support between photovoltaic systems, energy storage, and charging stations. Yijie Tools has keenly recognized the economic benefits of this integration. The project leader calculated that, as a manufacturing facility, electricity costs represent a significant expense. With the implementation of the solar-storage-charging project, the annual electricity generation exceeds 1.3 million kWh, yielding nearly one million yuan in annual revenue, which is more profitable than traditional investment products.

In terms of brand impact, the project has outstanding energy-saving and emission reduction benefits, equivalent to saving 468 tons of standard coal annually, serving as a “live advertisement” for low-carbon transformation within the industry, and facilitating a reduction in export “carbon tariffs”. Looking ahead, as the carbon trading market matures, the annual reduction of nearly 1,300 tons of CO₂ will become a new “green asset” for enterprises.

Zhongke Huachen, as the project operator, has demonstrated robust capabilities in providing comprehensive services to ensure efficient project implementation. Trina Solar, with its leading technological strength and contextualized solutions, supports enterprises in achieving green and low-carbon development. This dual-driven approach of “technology + service” is key to making the solar-storage-charging project a model for clean energy applications in the region.

Every kilowatt-hour of electricity embodies the fingerprints of sunlight, and every energy conversion is a poetic expression of light and shadow. Together, Yijie Tools, Zhongke Huachen, and Trina Solar are crafting a beautiful green narrative for our time—when factory rooftops begin to harness sunlight, and the pulse of industry synchronizes with the breath of nature, we can hear the ecological rhythm of sustainable development.
