CNBM SKT445M10 445W PERC Monocrystalline Solar Panel
SKT445M10 | PERC Technology | 120 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The CNBM SKT445M10 445W PERC Monocrystalline Solar Panel delivers exceptional energy performance for residential and commercial installations. This high-efficiency module features advanced PERC technology to maximize power output even in low-light conditions. Its robust design ensures reliable operation across diverse environmental challenges. The panel utilizes 120 half-cut monocrystalline cells arranged in a compact 1909x1134mm frame. With a module efficiency of 20.4%, it converts sunlight into electricity more effectively than standard panels. The positive power tolerance of 0 to +1% guarantees you receive at least the rated 445W output. This CNBM solar panel is engineered for longevity with a 25-year power warranty and a 12-year product warranty. Its anodized aluminum frame provides structural integrity against wind and snow loads up to 5400Pa. The anti-reflective coated tempered glass enhances light absorption while protecting internal cells. Ideal for large-scale solar farms or rooftop systems, it supports a maximum system voltage of 1500V. The IP68 junction box ensures complete protection against dust and water ingress. This reliable solution from China National Building Material International Corporation offers sustainable energy generation for decades.
Key Benefits
High Energy Efficiency: Achieves 20.4% module efficiency to maximize energy generation per square meter.
Advanced PERC Technology: Uses Passivated Emitter and Rear Cell design to boost output in low-light scenarios.
Superior Durability: Built with 3.2mm tempered glass and anodized aluminum to withstand 5400Pa mechanical loads.
Long-Term Warranty: Includes a 25-year linear power warranty and a 12-year product warranty for peace of mind.
Low-Light Performance: Optimized cell structure ensures consistent power generation during early morning or cloudy days.
How It Works
The CNBM SKT445M10 solar panel converts sunlight into usable electricity through a sophisticated photovoltaic process. Sunlight photons strike the 182mm monocrystalline silicon cells, exciting electrons to create an electric current. The PERC technology adds a passivation layer on the rear side to capture more light and reduce energy loss. Half-cut cell design divides each cell into two parts, reducing internal resistance and improving overall efficiency. This configuration minimizes power loss caused by shading or cell defects. The anti-reflective coating on the glass surface allows maximum light penetration into the cells. The anodized aluminum frame provides structural support while protecting edges from environmental stress. Electrical connections are safely routed through the IP68-rated junction box to prevent moisture damage. The output cables deliver the generated current to your inverter for conversion into AC power. This efficient system ensures reliable energy production for your home or business needs.
Photovoltaic Conversion: Sunlight photons excite electrons in the silicon cells to generate direct current electricity. This fundamental process creates the initial power output for the system.
PERC Enhancement: The rear passivation layer captures reflected light that standard cells would lose. This increases the total energy harvested from the same sunlight input.
Half-Cut Efficiency: Dividing cells into two halves reduces internal resistance and voltage drop. This design minimizes power loss even when parts of the panel are shaded.
