Trina Solar has officially commissioned its integrated photovoltaic (PV)-storage-charging-discharging microgrid demonstration station at its headquarters campus. This project integrates core modules—including PV power generation, energy storage for peak shaving, and bidirectional charging/discharging—via an in-house-developed intelligent microgrid control system, creating a smart clean energy ecosystem. It marks the company’s achievement of full-stack technological innovation in integrated energy services.
Centered on multi-energy coordination, the project enables efficient use of clean energy and intelligent grid interaction. The PV system has a total installed capacity of 196kW, with 184kW repurposed from components that have operated for over 15 years, maintaining a stable efficiency above 87%. A 12kW building-integrated PV curtain wall system further merges power generation with architectural aesthetics. The energy storage system, equipped with a 125kW/261kWh unit, employs a three-tier fire protection system and intelligent temperature control to maintain cell temperature differentials within 2.1°C, ensuring system efficiency above 90% and providing flexible support for dynamic power dispatch.
Trina Solar’s PV-storage-charging solution relies on an in-house intelligent control system, establishing a three-tier dispatch architecture of “sensing-decision-execution” to achieve efficient coordination among PV, storage, and charging equipment. Through a source-grid-load-storage collaborative optimization mechanism, the system enhances both PV self-consumption rates and charging efficiency, creating a safe, efficient, and bidirectional smart energy ecosystem. On the grid side, the solution integrates PV power generation, energy storage peak shaving, and vehicle-to-grid (V2G) technologies to form a closed-loop “generation-storage-utilization-regulation” system. V2G technology enables intelligent electricity feedback from electric vehicles (EVs) to the grid, boosting grid flexibility.
As EV adoption and grid interaction demands grow, this solution is transitioning rapidly from technical validation to large-scale deployment. The demonstration project validates the core value of system integration and intelligent dispatch. Future efforts will focus on optimizing energy conversion efficiency and dispatch algorithms to enhance clean energy consumption in industrial and commercial scenarios. By providing a replicable technical pathway for building new power systems, the solution supports low-carbon transformation across the entire energy value chain.
