Detailed product description

Area of ​​application & Target audience

The Trina Solar TSM-445 NEG9RC.27 is designed for residential and commercial roofs. Its compact dimensions of 1762 × 1134 mm make it particularly suitable for roofs with limited space where high power density is required. Compatibility with common inverters and optimizers simplifies system integration.

Everyday benefits

The bifacial double-glass construction enables additional energy yields by utilizing reflected light on the back of the module. At the same time, the glass-glass design offers increased resistance to moisture, mechanical stress, and environmental influences.

A positive power tolerance of 0/+5 W ensures a reliable minimum power output.

Technology & equipment

The module is based on 144 monocrystalline N-type i-TOPCon cells. This technology reduces degradation to a maximum of 1% in the first year and 0.4% annually in years 2–30.

The black 30 mm aluminum frame ensures stability and an aesthetically pleasing integration. The junction box is IP68 certified and equipped with three bypass diodes.

Connector system: MC4-EVO2
Photovoltaic cable: 4.0 mm², cable length 1100 mm (+)/1100 mm (−)

Efficiency & Environment

With a module efficiency of 22.3%, the TSM-445 offers a high energy yield per square meter.

Temperature coefficient Pmax: –0.29%/°C
NOCT: 43 °C (±2 °C)

The maximum system voltage is 1500 V DC (IEC), which allows for flexible string configurations.

compatibility & System integration

The module is compatible with standard inverters, power optimizers and mounting systems.

Mechanical load capacity:
5400 Pa snow load (test load)
4000 Pa wind load (test load)

This makes the module suitable for regions with increased snow or wind requirements.
