Trina Solar Panel 450W SLTSM-450NEG9R.28

The Trina Solar Panel 450W is a Vertex S+ series module manufactured with N-type i-TOPCon technology, offering a maximum power of 450W, an efficiency of 22.8%, and a positive power tolerance of 0/+5W. Its double-glass construction (1.6mm front + 1.6mm back) increases durability, while the use of 144 cells and multi-busbar technology translates into stable and efficient operation. The panel measures 1762 x 1134 x 30mm, weighs 21kg, and achieves a very good Pmax temperature coefficient of -0.29%/°C, which reduces power loss at high temperatures.

Higher performance in practice with N-type and MBB technology

The use of N-type cells combined with i-TOPCon technology allows for more efficient solar energy conversion, especially with long-term use. Additionally, multi-busbar technology improves current collection from the cells and increases light absorption, resulting in more stable energy production, even in partial shade. As a result, the panel better utilizes available operating conditions, regardless of the time of day.

Better performance at high temperatures

A power temperature coefficient of -0.29%/°C means the panel loses less efficiency on hot days than standard modules. In practice, this translates into higher energy yields in the summer, when the installation operates most intensively. Additionally, IP68-rated resistance ensures greater operational safety. The panel also features low degradation—a maximum of 1% in the first year and 0.4% annually thereafter. This ensures energy production remains at a predictable level for a long time. The manufacturer provides a 25-year product warranty and a 30-year power yield warranty, confirming the long-term durability of the solution.

Durability thanks to glass-glass construction

1.6mm thick double glass on the front and back increases the module's resistance to external factors. This design improves mechanical strength, confirming resistance to snow loads of up to 5400 Pa and wind loads of up to 4000 Pa. Additionally, the use of anti-reflective glass improves light transmission, which has a direct impact on performance. Thanks to its compact dimensions and standard construction, the panel is suitable for both residential and commercial installations. The dual-glass design in this model is primarily responsible for increased durability and resistance, not for double-sided operation, so it should be considered a monofacial module.

Parameters adapted to the installation

The module operates at an operating voltage of approximately 44.6 V and an operating current of 10.09 A, which allows for its use in standard PV system configurations. The short circuit current is 10.74 A, so it's worth checking their permissible operating ranges when selecting optimizers or other installation components. The panel is equipped with cables approximately 1100 mm long (in vertical orientation), which simplifies roof cabling planning.
