Trina Solar 450W SLTSM-450NEG9R.28 Panel

Trina Solar 450W SLTSM-450NEG9R.28 Panel is a modern photovoltaic panel based on advanced N-type i-TOPCon technology, delivering high efficiency and stable energy production in various weather conditions. With a maximum output power of 450 W and efficiency up to 22.5%, this panel is an excellent solution for both residential and commercial solar installations.

High efficiency and stable energy production

The combination of N-type i-TOPCon cells and Multi-Busbar (MBB) technology improves light absorption and reduces energy loss. As a result, the panel delivers stable performance even under diffuse sunlight and partial shading conditions. The positive power tolerance of 0 to +5 W guarantees performance at or above the nominal power rating.

Better performance in high temperatures

The panel features a low temperature coefficient of -0.29%/°C, meaning it loses less efficiency on hot days compared to standard photovoltaic modules. This ensures higher energy yields during summer months when solar systems operate at peak intensity.

Durable glass-glass construction

The dual 1.6 mm tempered glass construction increases resistance to moisture, wind, and mechanical stress. The panel withstands snow loads up to 5400 Pa and wind loads up to 4000 Pa. Anti-reflective glass coating improves light transmission and contributes to higher overall efficiency.

Long-lasting reliability

The panel is designed with low degradation rates — a maximum of 1% during the first year and only 0.4% annually afterward. This ensures stable and predictable energy production over many years. The manufacturer provides a 25-year product warranty and a 30-year performance warranty.

Suitable for various installations

Standard dimensions and optimized electrical parameters make the panel easy to integrate into different photovoltaic systems. Approximately 1100 mm long cables simplify installation and cable routing on rooftops.
