Model SS470M10GH-20/UH | N-Type TOPCon | 120 Half-Cut Cells | Bifacial | 1500V System Voltage
The Smart Solar Technologies SS470M10GH-20/UH N-Type TOPCon bifacial solar panel delivers efficient 470W power in a sleek full black design. This advanced module combines 120 half-cut N-type cells with state-of-the-art SMBB technology for higher energy yield. The bifacial glass-glass structure captures sunlight from both sides to increase total system output. Its robust 1500V DC rating supports modern high-voltage string designs for residential, commercial, and industrial projects. Optimized light trapping and current collection help reduce levelized cost of energy over the module lifetime. Strong mechanical performance and excellent PID resistance support reliable operation in harsh climates. This panel offers a high-efficiency solution for installers seeking premium aesthetics with proven durability. It is engineered for rooftops, carports, ground mounts, and utility-scale arrays that demand long-term performance.
High 470W output for compact arrays: Each module delivers up to 470W, enabling powerful systems even in limited roof space. Installers can design smaller arrays while meeting demanding production targets.
N-Type TOPCon with SMBB technology: N-type cells with SMBB design improve light capture and current collection. This architecture boosts efficiency and supports stable energy generation over time.
Bifacial glass-glass construction: The bifacial design increases total energy harvest by using reflected light on the rear side. Glass-glass lamination also enhances durability and environmental resistance.
Strong mechanical load resistance: The panel is engineered for 5400Pa front load and 2400Pa rear load. It is suitable for regions with heavy snow, strong wind, or challenging mounting conditions.
Long-term performance warranties: A 12-year product warranty and 30-year linear power warranty support investment security. Power degradation is tightly controlled to ensure dependable output.
The Smart Solar Technologies SS470M10GH-20/UH solar panel converts sunlight into clean DC electricity using advanced N-type TOPCon cells. When light strikes the 120 half-cut mono cells, photons excite electrons and create an electric current. SMBB busbar architecture collects this current efficiently and routes it through the cell strings. The bifacial glass-glass module captures irradiance on both the front and rear sides for higher yield. An integrated junction box with IP68 protection safely combines the output and connects to system cabling. The module operates within a wide temperature range while maintaining stable power thanks to optimized coefficients. Once wired into an inverter, the DC power is converted to AC for building loads or grid export. This process runs continuously during daylight, reducing energy costs and carbon emissions over the panel lifetime.
N-Type TOPCon cell conversion: N-type TOPCon cells provide improved carrier lifetime and lower degradation. They maintain higher efficiency under varied temperatures and operating conditions, supporting reliable daily energy production.
Bifacial energy harvesting: The transparent rear glass allows light from ground reflection or nearby surfaces to reach the rear cells. This bifacial effect can increase total module energy by around 5–25 percent depending on site conditions.
Electrical integration and protection: The IP68 junction box protects connections against moisture and dust ingress. Integrated bypass diodes help reduce the impact of shading, while the 1500V system rating supports efficient string design and reduced balance-of-system costs.
