36 Trina Solar 445W Vertex S+ dual-glass N-type TopCon solar modules

The Trina Solar Vertex S+ (MPN: TSM-NEG9R.28) is an efficient solar panel with an output of 445W that uses monocrystalline TOPCon cells and dual-glass technology. Thanks to multi-busbar technology, it offers improved absorption, low series resistance, improved current dissipation, and reliability. It is certified for extreme wind and snow loads of 5400 - 4000 Pa and features highly transparent, 1.6 mm thick glass with anti-reflective coating. The frame is made of 30 mm wide, anodized aluminum alloy

N-TOPCon cell technology

Advanced TOPCon technology (Tunnel Oxide Passivated Contact) is a further development of PERC technology and aims to increase the efficiency of solar cells. The solar modules are coated with an ultra-thin oxide layer followed by a conductive layer, resulting in what is known as a passivated contact. As a result, the performance of the solar cell is improved in low light conditions, leading to higher annual energy production.

Dual glass design

The solar module is equipped with improved dual 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

Multi-busbar technology

Each PV module has busbars that serve as conductor rails and are firmly connected to each solar cell. They collect the direct current generated and feed 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.

Universal solution for residential and C&I roofs

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