36 Trina Solar 450W Vertex S+ dual-glass N-type TopCon solar modules

The Vertex S+ from Trina Solar (MPN: TSM-450 NEG9R.28) is a 450W double-glass solar module that delivers the best possible yield using a range of modern technologies. The high-density cell connection minimizes cell spacing, while multi-busbar and N-type i-TOPCon technology increase light yield, reduce series resistance, and improve current conduction. This allows you to achieve an efficiency of 22.5% and stable yields even in diffuse light conditions, such as cloud cover or hours of shade. The robust double-glass construction ensures excellent resistance to fire and environmental influences and is certified for test loads of 5,400 Pa snow load and 4,000 Pa wind load. Thanks to a positive power tolerance of 0/+5 W, the panel delivers at least the rated power during operation. Aging is extremely low, with 1% degradation in the first year and only 0.4% in years 2 to 30, ensuring high energy yields in the long term. In addition, the module is widely compatible with common inverters and offers flexible installation options, allowing you to easily integrate it into new or existing systems.

TOPCon cell technology

N-type i-TOPCon is a modern cell technology with passivated contacts (tunnel oxide + polysilicon) that greatly reduces losses at the cell surface. This gives you more power per area, better performance in heat, and stable yields even in indirect light. Degradation is very low: approx. 1% in the first year, then around 0.4% per year. In combination with multi-busbar and double glass, reliability is increased and the module can be easily integrated with standard inverters.

High-density cell connection technology

This reduces the gaps between the solar cells to a minimum. As a result, the module uses more active surface area, captures more light, and converts it into electricity more efficiently. This increases the output per module and reduces electrical losses. In combination with the multi-busbar connection, the current flows more evenly – for stable, reliable yields.

Multi-Busbar Technology

Each PV module has busbars that serve as power rails and are permanently connected to each solar cell. They collect the generated direct current and forward it to the busbars. Trina Solar uses a larger number of busbars to reduce shadow effects, shorten transport distances, and minimize resistance in the modules.

Double glass design

The solar module is equipped with improved double glass, which makes it less susceptible to microcracks and scratches on the back during installation. This gives it increased mechanical resistance and strength. It is particularly suitable for use in coastal areas, in high temperatures and high humidity, and in demanding environments. Other great features:

• Outstanding fire resistance
• Weather resistance
• Resistance to salt spray, sand dust, or ammonia

Universal solution for residential and commercial/industrial roofs

The module has been designed to be easily integrated into existing inverters and various mounting systems. In addition, it is optimally dimensioned and lightweight, which facilitates handling and installation. This makes the panel the ideal solution for roofs with limited load-bearing capacity.

Degradation explained

This means that the performance of the 450W module decreases only slightly over the years. In the first year, it decreases by a maximum of 1%, from 450W to around 445.5W. From year 2 to 30, the decrease is a maximum of 0.4% per year. The bottom line is that after 30 years, the module still delivers around 87.4% of its initial output – that's about 394 W – ensuring you stable long-term yields.
