18BB66H-710-725w

The SoleHoy 18BB66H series is a next-generation, ultra-high-power solar module engineered for the global utility-scale and large commercial & industrial (C&I) solar energy market. Leveraging 210N large-format N-type TOPCon technology, 18BB busbar design, and dual-glass construction, it delivers exceptional bifacial power gain and industry-leading durability. This module is the ideal solution for large-scale ground-mounted power plants, agrivoltaic systems, and desert projects, providing maximum energy yield and cost-effective clean energy across Southeast Asia, Africa, the Middle East, and beyond.
Key Advantages
Record-Breaking Efficiency & Bifacial Gain: Equipped with 210N N-type monocrystalline half-cut cells, 18BB busbar, and SMBB technology, the module achieves a maximum conversion efficiency of 23.34%. Under BNPI conditions, the advanced bifacial design delivers a staggering equivalent maximum power output of up to 800Wp, significantly boosting electricity production per unit area and maximizing land utilization efficiency.
Uncompromising Rugged Reliability: Certified to ISO 9001, ISO 14001, ISO 45001, and IEC 62941 standards. Featuring a robust dual 2.0mm tempered glass structure, it withstands 25mm hail impacts and extreme mechanical loads. With an IP68 junction box and excellent PID resistance, it performs flawlessly in harsh environments, including high humidity, sandstorms, and extreme temperatures ranging from -40℃ to +85℃.
Optimal Long-Term ROI: The ultra-low temperature coefficient of -0.290%/°C minimizes power loss in scorching high-temperature climates, a critical advantage for tropical and desert installations. The 1500V DC system voltage reduces BOS costs, while the ultra-low degradation rate ensures higher energy retention over the lifespan, delivering superior long-term returns on investment for utility-scale projects.
