Trina Solar publishes white paper on 210mm n-type i-TOPCon advanced technology
Upgraded Vertex N 605W/695W leads among utilities

Trina Solar published the Trina Solar 210mm Vertex N Product White Paper in January. The newly upgraded Vertex n-type modules of 605W+695W with efficiency up to 22.4% are setting the standard for power station modules in every respect, stepping up the industry's acceleration into the n-type era. Trina Solar is committed to building the 210mm product technology platform with a high degree of compatibility. The white paper serves as a guide for the solar industry in each phase: choosing a technical route, developing product parameters, empirical testing, mass production and delivery.

Powered by Vertex N series, utility-scale solar power plants are upgrading to n-type 600W+

The advanced i-TOPCon cells and 210mm technology have comprehensively upgraded the Vertex N series with improved cell efficiency and higher module power, bringing module efficiency to as high as 22.4%, with power reaching 605W and 695W for C&I PV applications and utility settings, respectively.

With Vertex N products, utilities are fully embracing the era of n-type 600W+, promoting the LCOE-oriented principle with higher efficiency, power, energy yield and reliability that are in line with Trina Solar’s Vertex family gene.

Building n-type ecosystem with full-scenario application

Guided by value, Trina Solar’s n-type full-scenario solutions help customers receive benefits across diverse terrains, including mountains, water surfaces and deserts.

With a power rating up to 605W and an innovative design of size and low voltage, the next generation of Vertex N 605W modules make an ideal partner for tracker systems, creating a perfect fit for a set of 104-meter-long trackers. Six to 12 more modules can be mounted on a tracker, compared with the conventional n-type 72-cell and 78-cell modules. For example, in a 4MW ground-mounted power station in Dubai, Vertex n-type modules and trackers can reduce BOS costs by 2.84% compared with the reference 182mm modules.

The Vertex N 695W modules offer advantages in ultra-low degradation, optimized bifaciality, and ultra-low operating temperature coefficient to reduce CAPEX and LCOE of power stations, with some in the industry calling them the “Star of ground-mounted power stations.” For example, a 100MW ground power station in Brazil using Vertex n-type modules and trackers rather than conventional 182mm n-type 72-cell modules can cut project CAPEX by 2.44% and LCOE by 2.97%.

Five technical strengths and empirical projects that prove Vertex N’s value

Vertex N technology has five major advantages: high conversion efficiency, bifaciality, power, low temperature coefficient and degradation. As the efficiency of p-type PERC technology approaches its upper limit, there is an obvious trend toward n-type tech in the industry.

For many years, Trina Solar has been developing n-type technology and has accumulated a wealth of experience in empirical testing and high-volume delivery. The results of a field test project in Hainan over one year and a floating power station in Changzhou over six years reveal the power degradation rate of Trina Solar's n-type modules is far below the industry average of 1% in the first year, with a 0.4% linear degradation rate year by year that guarantees long-term benefits for customers. In addition, Trina Solar has extensive experience in delivering a total of 500MW n-type i-TOPCon modules for Changzhi, Tongchuan, and other large projects. In December, Trina Solar’s 210mm n-type i-TOPCon cells began rolling off the production line.

Trend: 210mm n-type leads the industry into 700W+ era

TrendForce, an independent agency, has forecast that n-type technology will dominate cell capacity expansion in 2023. With the acceleration of n-type module production, a shift toward 700W is taking place.

In the n-type era, 210mm technology and n type i-TOPCon cell technology will work together by combining strengths to highlight the lower LCOE-oriented principle. Trina Solar will maintain its leadership and meet the increasing market demand for high- performance PV modules.
