TSEC TS54-CMH-425 H1 TOPCon Monocrystalline Solar Panel
TS54-CMH-425 H1 | TOPCon | 108 Mono-Crystalline Cells | Monofacial | 1500V System Voltage
Product Overview
The TSEC TS54-CMH-425 H1 TOPCon Monocrystalline Solar Panel delivers exceptional energy performance for modern residential and commercial installations. This high-efficiency module features advanced TOPCon technology with 108 monocrystalline silicon cells arranged in a 6x18 configuration. The panel achieves a maximum power output of 425 Wp with a module efficiency of 21.8%. It is designed to withstand harsh environmental conditions including salt mist, mechanical loads up to 5400 Pa, and extreme temperatures ranging from -40°C to +85°C. The robust construction includes an anti-salt mist frame, IP68-rated junction box, and low water vapor transmission encapsulant. This Taiwan-made solar panel offers superior low-light response and better temperature coefficients compared to standard modules. The TSEC TS54-CMH-425 H1 represents a sustainable investment in green energy with minimal degradation over its 30-year lifespan.
Key Benefits
Advanced TOPCon Technology: Tunnel Oxide Passivated Contact cells reduce electron recombination for higher efficiency and power output.
Superior Environmental Resistance: Certified against the toughest salt mist tests and highest mechanical load standards in the PV industry.
Excellent Low-Light Performance: Better low light response ensures consistent energy generation during dawn, dusk, and cloudy conditions.
Minimal Power Degradation: Zero light-induced degradation with only 0.42% annual degradation rate ensures long-term value retention.
Optimized Temperature Coefficients: Better temperature coefficient (-0.29%/°C) reduces power loss in hot operating environments.
How It Works
The TSEC TS54-CMH-425 H1 TOPCon Monocrystalline Solar Panel converts sunlight into usable electricity through advanced photovoltaic processes. When photons strike the 182mm TOPCon solar cells, they excite electrons within the monocrystalline silicon structure. The tunnel oxide passivation layer minimizes electron recombination at the cell surface, allowing more electrons to flow through the external circuit. This innovative design results in higher voltage and current output compared to conventional solar cells. The panel's 108 cells are electrically connected in series to achieve the optimal 425 Wp power rating. The encapsulant material with low water vapor transmission protects the internal components from moisture damage. The anti-salt mist frame provides structural integrity while preventing corrosion in coastal environments.
Photon Absorption and Electron Excitation: Sunlight photons penetrate the PV-coated glass and strike the TOPCon cells. This energy excites electrons within the silicon lattice, creating free electron-hole pairs. The passivation layer prevents these electrons from recombining prematurely, maximizing current flow.
Electrical Current Generation: The excited electrons flow through the internal circuit of the 108 series-connected cells. This movement generates direct current electricity at 33.01 V and 12.9 A under standard test conditions. The power output reaches 425 Wp with 21.8% efficiency.
Environmental Protection and Durability: The IP68-rated junction box with three bypass diodes protects against moisture and enables current flow during partial shading. The anti-salt mist frame and low WVTR encapsulant ensure decades of reliable operation in harsh climates.
