Advanced N-Type SMBB Bifacial Solar Technology
Mak Tek Engineering supplies the cutting-edge Cosmos N-type Bifacial Monocrystalline PV Module series (Model HS 210R-132 TC-D) across Bangladesh. Engineered for industrial factory rooftops, commercial enterprises, and high-yield ground-mounted solar power plants, these modules leverage high-density 132 half-cell (210R) architecture and Super Multi-Busbar (SMBB) interconnects to deliver an impressive peak power output of 620W to 640W with up to 23.7% module efficiency.
Key Engineering Advantages & Performance Benefits
- N-Type SMBB Half-Cell Architecture: Super Multi-Busbar (SMBB) technology delivers a significantly more uniform current distribution across internal cells, cutting resistive heat losses and substantially mitigating micro-crack propagation risks.
- High Bifacial Energy Yield (80 ± 5%): Symmetrical dual-glass construction captures albedo reflection from rooftop and ground surfaces, boosting total system energy generation up to 704W (BNPI) and lowering Levelized Cost of Energy (LCOE).
- Superior Low-Light & Temperature Performance: Exceptional spectral response under low-light, cloudy, or overcast dawn/dusk conditions with an industry-leading temperature coefficient of Pmax at -0.28%/°C, ensuring stable performance during extreme South Asian summer heat.
- Negligible LID / Anti-PID Immunity: Zero Boron-Oxygen light-induced degradation (LID) and negligible Light-and-elevated Temperature-Induced Degradation (LeTID), paired with strict anti-Potential Induced Degradation (PID) cell passivation.
- Rigorous Industrial Environment Adaptability: Tested and certified against severe salt spray corrosion, ammonia gas exposure, blowing sand, and industrial atmospheric chemical contaminants.
- Robust Dual-Glass Mechanical Integrity: Built with 2.0mm + 2.0mm anti-reflective (AR) coated heat-strengthened front and rear glass, framed in anodized aluminum alloy, engineered to withstand 5400 Pa front mechanical snow/wind loading and 2400 Pa rear wind suction.
