Superior Low-Light Performance
N-Type 210mm half-cut cells sustain up to 97% output under 200 W/m², outperforming most Tier-1 modules in cloudy or low-irradiance conditions. TOPCon technology is built on an N-type silicon substrate with an ultra-thin passivation oxide layer. TOPCon's passivated contact structure minimizes electron recombination and energy loss, enabling module conversion efficiencies at the top of the industry, ranging from 22% to 24.8%.
Ultra-Low Annual Degradation
Advanced anti-PID monocrystalline cells ensure only 0.40% annual loss, retaining over 87% power after 30 years, exceeding Tongwei and Trina benchmarks. N-type TOPCon cells exhibit virtually no light-induced degradation during the initial light-soaking period. Combined with Sunpal's anti-PID monocrystalline cell design, the module maintains an industry-leading annual degradation rate of just 0.40%, retaining over 87% of rated power after 30 years. This anti-PID, anti-LID TOPCon solar module significantly outperforms conventional P-type mono modules.
Exceptional Mechanical Strength
Double-tempered glass and anodized aluminum frame withstand 5400 Pa front / 2400 Pa rear loads, ensuring durability under wind, snow, or environmental stress.
Max Energy Yield & Lowest LCOE
SMBB technology and bifacial design deliver up to 25% rear-side gain, achieving a massive 893.8W output. By capturing ground-reflected sunlight (albedo), bifacial TOPCon panels can deliver an additional 2% to 4% annual energy yield in real-world ground-mount solar farm deployments. Compared with conventional P-type PERC modules, N-type TOPCon technology provides a 1.5% to 2% higher baseline efficiency and higher power density, helping reduce racking, mounting, and overall BOS costs. Although TOPCon modules typically carry a 5% to 10% higher upfront procurement cost, their improved energy yield and lower BOS requirements can help optimize LCOE and support faster ROI for TOPCon solar panels for utility-scale solar farms.
