Trina 460Wp TSM-NEG9R.28-460 N-type Mono black frame solar panel

Trina Solar NEG9R.28-460W Black Frame N-type Mono DG

The SOL-TRIS-NEG9R.28-460-BF is a 460 W nominal power, N-type i-TOPCon technology-based, dual-glass solar module that operates with an efficiency of up to 23.0%. Thanks to modern cell technology, low annual degradation, and outstanding mechanical resistance, it is an ideal choice for residential and small-scale commercial rooftop systems where long-term stability is a key consideration.

460 W power output and 23% efficiency – more energy in a smaller footprint

The 460 W maximum power output and 0/+5 W positive power tolerance ensure that the system operates at or above the rated value. The 23.0% module efficiency is outstanding in this size category, allowing for greater installed capacity even on smaller roof areas.

The advantage of N-type i-TOPCon cell technology is lower first-year degradation (only 1%) and a subsequent annual power decline of no more than 0.4%. This results in higher energy production and a better return on investment over the long term compared to conventional technologies, particularly for projects where a 20–30-year operational lifespan is a realistic expectation.

Dual-glass design – enhanced reliability and lifespan

The dual-glass construction increases the module’s mechanical stability and resistance to environmental impacts. Snow loads of 5,400 Pa and wind loads of 4,000 Pa enable safe installation even in regions with higher stress levels.

The maximum system voltage of 1,500 V DC supports the creation of longer strings, which optimizes system design and can reduce specific installation costs. The IP68-rated junction box and the robust, 30 mm black aluminum frame ensure stable, reliable operation over the long term.

Optimized size for residential and C&I roofs

The dimensions of 1762 × 1134 × 30 mm and a weight of approximately 21 kg enable easy handling and efficient transport. The 144-cell design, multi-busbar technology, and high current collection efficiency collectively contribute to better light utilization and stable performance.

The module is compatible with the major inverters, optimizers, and mounting systems available on the market, allowing for flexible integration into both new and existing systems. It offers a reliable, universal solution for residential single-family homes, larger residential properties, and small industrial roofs.

25- and 30-year warranties – a long-term investment

The product comes with a 25-year manufacturer’s warranty and a 30-year performance warranty. The favorable degradation curve ensures that the module will generate stable yields for decades, which is particularly important for investments planned from a financial perspective.

The combination of the long warranty period and N-type technology means that the system will deliver competitive performance not only today but also 20–30 years from now.

SOLARKIT Reviews

The SOL-TRIS-NEG9R.28-460-BF is an exceptionally strong choice for those seeking a high-efficiency, long-lasting, and reliable dual-glass solar module for residential or small-scale commercial projects. The combination of 460 W power output, N-type i-TOPCon technology, and low annual degradation ensures stable, predictable energy production.

It is particularly advantageous in rooftop systems where available space is limited but expectations are high. It is highly recommended for quality investments designed for the long term.
