TSEC TS66-CMH-545 H1 545W N-Type TOPCon Monocrystalline Solar Panel
Model TS66-CMH-545 H1 | N-Type TOPCon | 132 Monocrystalline Cells | Monofacial | 1500V System Voltage
Product Overview
The TSEC TS66-CMH-545 H1 N-Type TOPCon monocrystalline solar panel delivers 545 watts of high-density power in a sleek, durable format ideal for commercial rooftops and large ground mount arrays. This advanced module uses 182 mm N-Type TOPCon cells arranged in a 132 cell layout to achieve up to 23 percent efficiency, helping more energy be produced from every square meter of roof or land. A 12 year product warranty and long term linear power warranty are included, ensuring dependable output for decades. The panel is engineered for demanding climates with a 1500 volt system rating, tough mechanical design, and a robust IP68 junction box. With its optimized temperature coefficients and low annual degradation rate, this module is designed to support stable, predictable energy yields and a lower levelized cost of electricity over the system lifetime. Installers and project developers can rely on this panel when high performance and long term bankability are required.
Key Benefits
High power density for limited space: Each module supplies up to 545 watts, allowing system designers to reach target capacity using fewer panels and reduced mounting hardware.
Outstanding efficiency up to 23%: The N-Type TOPCon cell design and optimized 6x22 layout push conversion efficiency above many conventional mono modules, increasing energy harvested from available roof area.
Robust long term performance: A total degradation rate of only 0.42 percent per year supports 91.4 percent output at 20 years and 87.4 percent at 30 years for reliable long term energy production.
Dependable operation in harsh climates: The panel operates between -40 and 85 degrees Celsius, uses an anti salt mist frame, and passes high mechanical load testing, making it suitable for coastal and heavy snow regions.
Installer friendly size and design: A 2093 by 1134 millimeter footprint, 25.5 kilogram weight, and 1500 millimeter factory cables simplify handling, string design, and quick integration with modern mounting systems.
Lower LCOE for projects: Improved low light response, reduced temperature losses, and high efficiency combine to improve annual yield and help drive down system level energy costs over time.
How It Works
This TSEC TS66-CMH-545 H1 solar panel converts sunlight into usable direct current electricity using advanced N-Type TOPCon monocrystalline cells. Each of the 132 cells is interconnected and laminated under tempered glass to protect it from weather while allowing maximum light transmission. When sunlight strikes the 182 millimeter cells, photons are absorbed and free electrons are generated within the silicon structure. The built in electric field within each cell drives these electrons toward the conductors, creating current that flows through the module cables. Under standard test conditions the panel delivers a maximum power of 545 watts at around 40.78 volts DC and 13.37 amps. The module is then wired in series and parallel strings to build higher system voltages, often up to 1500 volts, which are suited to commercial scale inverters. Optimized temperature coefficients and low light behavior help maintain stable output across real world operating conditions, from cold bright days to hot summer afternoons.
N-Type TOPCon cell architecture: The monocrystalline TOPCon cells use a thin tunnel oxide layer and passivated contacts to reduce recombination losses and improve carrier collection. This design increases efficiency and supports additional energy yield compared to many standard P-Type cells under the same irradiance conditions.
Optimized electrical operating point: At maximum power, the module operates at a voltage of 40.78 volts and a current of 13.37 amps, which gives a strong balance between string length and inverter compatibility. Modern inverters track this operating point using maximum power point tracking, ensuring that the array consistently runs at or near its most efficient point during the day.
Durable module construction and safety: The front glass, encapsulant, backsheet, and anti salt mist frame work together to seal the cells from moisture, dust, and mechanical stress while still allowing efficient heat dissipation. An IP68 junction box with three bypass diodes manages current flow and reduces shading losses, while the 1500 volt rating and Class II protection help the panel integrate safely into modern high voltage systems.
