Sungrow Outlines 10 Key Technological Trends in Solar and Storage Development

Dr. David Zhao, Senior VP of Sungrow, recently highlighted 10 major technological trends driving the solar and storage industry. These trends aim to support energy transition and sustainable economic growth despite challenges in power infrastructure, including supply chain security, clean energy consumption, and cost management.

Here are the 10 key trends identified by Dr. Zhao:

• High Density and High Efficiency
  Inverters are incorporating Silicon Carbide (SiC) and Gallium Nitride (GaN) devices, improving power density and efficiency. Sungrow pioneered the use of SiC in PV inverters with its SG350HX in 2021.
• High-Voltage and High-Power Systems
  Inverter power is increasing, with DC voltage moving toward 2000V. Sungrow's 2000V DC PV system set a new benchmark for cost reduction and efficiency.
• Grid Forming
  Grid-forming technologies are crucial as renewable energy penetration increases. Sungrow has led in this area, offering solutions to support grid stability, with capabilities like flexible inertia support and rapid off-grid debugging.
• Digitalization and AI Empowerment
  AI and digitalization are enhancing the lifecycle of PV plants, improving reliability and efficiency. Sungrow’s AI-driven battery management system tracks parameters for early fault detection and better performance.
• Secure and Reliable Systems
  Systems with a 30-year design lifespan are becoming the norm. Sungrow invests in real-world tests to ensure the safety and reliability of its energy storage systems, setting new industry standards.
• Topology Innovation
  Sungrow developed the world’s first 6MW 35kV Solid State Transformer-based inverter, improving power conversion efficiency and achieving 98.5% efficiency.
• High-Precision Simulation
  Advanced simulations allow for better modeling of solar, wind, and storage systems, reducing development costs and time while improving accuracy in real-world conditions.
• Virtual Power Plants (VPPs)
  VPPs aggregate distributed energy resources to optimize grid dispatch, reduce costs, and improve energy reliability and grid stability.
• Source-Grid-Load-Storage-Carbon Integration
  Integrated management of energy systems can drive clean energy integration and help achieve carbon reduction goals. Sungrow is working on the world's largest multi-energy microgrid project in Saudi Arabia.
• Green Hydrogen, Ammonia, and Methanol
  Green hydrogen is becoming increasingly important, with renewable energy-based electrolysis driving its production. Hydrogen production systems designed for renewable energy fluctuations are key to large-scale hydrogen production.

Sungrow continues to innovate in these areas to tackle challenges and create a sustainable future with industry partners.
