SMTE 550W Monocrystalline N-Type Half-Cell Solar Panel

Power your home, business, or industrial facility with our 550W Monocrystalline N-Type Half-Cell Solar Panel. Engineered with 144 Grade-A monocrystalline half-cells and cutting-edge N-Type technology, this high-performance module delivers exceptional power density, minimized internal resistance, and maximum energy generation—even in low-light and harsh weather conditions.

Key Features & Benefits

550W High-Density Power Output: Delivers maximum energy yield per square meter for residential, commercial, and utility installations.

Next-Gen N-Type Cell Technology: Significantly reduces Light-Induced Degradation (LID) and LeTID attenuation to ensure long-term energy retention.

Outstanding Low-Light Performance: Captures and converts sunlight efficiently during overcast days, early mornings, and late afternoons.

144 Half-Cell Layout: Lowers internal resistive losses and mitigates power drops caused by partial shading or debris.

High System Voltage Compatible: Certified for up to 1500V DC systems, enabling longer string designs and lower balance-of-system (BOS) costs.

Heavy-Duty Weatherproof Build: Features a 30 mm silver anodized aluminum frame, Grade-A black cells, and a durable white backsheet built to handle extreme temperatures (-40°C to +85°C).
