Trina Solar 450W Solar Panel
Trina Solar 450W SLTSM-450NEG9R.28 is a high-efficiency photovoltaic module from the Vertex S+ series using N-type i-TOPCon technology. It delivers up to 450 W output with 22.8% efficiency and a +0/+5 W power tolerance. The 144-cell multi-busbar design improves current collection and stability, while double-glass construction enhances durability. With low degradation and strong temperature performance, it is suited for long-term residential and commercial solar installations.
The panel delivers a maximum power output of 450 W with an efficiency rating of 22.8% and a positive power tolerance of 0/+5 W, ensuring consistent real-world performance. It uses 144 half-cut cells combined with multi-busbar (MBB) technology, which improves current collection, reduces resistive losses, and enhances energy output stability under varying irradiance conditions, including partial shading.
A key feature is its N-type cell architecture with i-TOPCon technology, which improves electron transport and reduces degradation over time. This supports higher long-term energy yield compared to conventional P-type modules, particularly during extended operational lifespans.
The module is built with a double-glass structure consisting of 1.6 mm tempered glass on both the front and rear sides. This increases mechanical strength and environmental resistance, while also improving protection against moisture, UV exposure, and microcracks. It is rated to withstand snow loads up to 5,400 Pa and wind loads up to 4,000 Pa.
Temperature performance is optimized through a low power temperature coefficient of -0.29%/°C, reducing efficiency loss in high-temperature conditions and improving summer energy production. The panel also features low degradation rates, with approximately 1% loss in the first year and around 0.4% annually thereafter, supporting stable long-term output. Manufacturer warranties typically extend to 25 years for the product and 30 years for power output.
Electrical characteristics include an operating voltage of approximately 44.6 V and operating current of 10.09 A, with a short-circuit current of 10.74 A. Cable length is approximately 1100 mm in vertical configuration, allowing flexible installation planning within PV systems.
Overall, the panel is designed as a durable, high-efficiency solution for stable long-term solar energy generation in a wide range of installation environments.
