Trina Solar 445w Vertex s+ dual glass N-Type TopCon solar module

The Trina solar Vertex s+ (mpn: tsm-neg9r.28) is an effective solar module with an output of 445w that uses monocrystalline TOPCon cells and dual-glass technology. Thanks to the 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 has highly transparent, 1.6 mm thick glass with anti-reflective coating. The frame is made of a 30 mm wide, anodized aluminium alloy.

N-TOPCon cell technology

The 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 provided with an ultra-thin oxide layer and a subsequent conductive layer, which leads to a so-called 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 an improved dual glass, which makes it less susceptible to micro-cracks 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
• Resistance to weathering
• Resistance to salt spray, sand dust or ammonia

Multi-busbar technology

Each PV module has busbars that act as busbars and are permanently connected to each solar cell. they collect the generated direct current and transmit 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 CundI roofs

The module has been designed so that it can be easily integrated into existing inverters and various mounting systems. It is also optimally dimensioned and lightweight, which makes it easier to handle and install. For this reason, the Vertex s is the ideal solution for roofs with limited load-bearing capacity.
