High Efficiency & Power Output

With a panel efficiency of 23% and a maximum power output of 620W, this module optimizes energy generation even in limited space459.

Utilizes N-type TOPCon cells and bifacial technology, enabling power generation from both sides and increasing energy yield by up to 30% in reflective environments (e.g., snow, sand, or light-colored surfaces)211.

 

Robust Dual-Glass Construction

Features 2.0+2.0mm tempered double glass for enhanced durability, weather resistance, and a lifespan exceeding 30 years45.

The frameless or anodized aluminum alloy frame design ensures resistance to corrosion, PID (Potential Induced Degradation), and low LID (Light-Induced Degradation)511.

 

Advanced Technology Integration

Incorporates half-cut cell design and multi-busbar (MBB) technology to minimize energy loss and improve shading tolerance49.

Operates efficiently across a wide temperature range (-40°C to 85°C) and performs well under low-light conditions5.

 

Certifications & Warranty

Certified to international standards (TÜV, CE, ISO, IEC) and equipped with an IP68-rated junction box for waterproof and dustproof reliability911.

Backed by a 30-year linear power warranty, ensuring long-term performance stability45.

 

Versatile Applications

Suitable for large-scale solar farms, commercial rooftops, and industrial projects. Its 144-cell configuration and compatibility with DC1500V systems support seamless integration into high-voltage setups.
