DNV GL, an independent testing and certification organization for the energy industry, has published a report disclosing that Trina Solar’s Vertex 210mm 545W mono-facial modules can reduce the balance of system (BOS) cost by up to 6.3% and levelized cost of energy (LCOE) by 5.8% as compared to 182mm 535W mono-facial modules.

The DNV GL report also says the Vertex 210mm 600W mono-facial module performs just as well in reducing BOS and LCOE (5.6%) compared with the 182mm 585W module.

The report findings are based on an assessment done last month of a solar energy project in Aomori prefecture, Japan.

The coordinates are : 

At the site, with the 166mm 450W mono-facial module as the benchmark, DNV GL compared the BOS cost and LCOE of the Vertex 210mm 545W mono-facial module and the 182mm 535W mono-facial module, as well as the Vertex 210mm 600W mono-facial module and the 182mm 585W mono-facial module with landscape-fixed tilts. In this assessment, the capacity of the AC side was 10 MW with the same DC/AC ratio, and adopting the four-row landscape-fixed tilts commonly used in Japan and with mainstream string inverters. In order to objectively compare the impact of different types of modules on the BOS cost and LCOE, the project as a whole used similar meteorological data and design input conditions. The five comparisons were all based on local costs to be consistent, comprehensive and objective when comparing local construction cost, on-grid
tariffs, operational and maintenance costs, and land costs.

Parameters of the power plants

Assessment results: BOS fell 6.3%, and LCOE fell 5.8%, maximizing customer value Vertex’s innovative low-voltage design connects more than 1,500V modules so that significant BOS cost savings and LCOE reduction are achieved on the fixed-tilt by greatly reducing the number of module strings by connecting 8-9 more modules in a single string than is the case with 182mm modules.

First, it can cut material and labor costs involving DC cables and racking systems, and thus reduce initial investment. Second, the ultra-high power can reduce the number of modules in the setup and speed up construction, further reducing total investment costs. Finally, with superior power generation, Vertex is able to maximize value for customers by ensuring minimum LCOE.

According to the assessment in Japan, Trina Solar’s Vertex 210mm 545W mono-facial module can reduce BOS by up to 6.3% and reduce LCOE by 5.8% compared with the 182mm 535W mono-facial module, and the Vertex 210mm 600W mono-facial module performs just as well in reducing BOS and LCOE (5.6%) compared with the 182mm 585W module.

Comparison of estimated costs
The DNV GL report found Trina Solar’s Vertex 210 mm module cuts costs in many ways.
As the PV industry embraces grid parity, the Vertex series has a prominent edge in LCOE as a result of Trina Solar’s continued push to reduce costs and improve efficiency. February’s assessment followed two earlier assessments of Trina Solar Vertex modules by DNV GL in January and December.

The assessment in December found that the 545W bifacial dual-glass Vertex module with single-axis (1P) tracker has the best LCOE, 3.5% less, and performs significantly better than the conventional 166mm-450W and 182mm-535W modules in BOS costs.

DNV GL’s assessment in January focused on the LCOE advantage and value of the Trina 600W+ Vertex Bifacial Dual-Glass Module with Single-Axis 2 portrait installation (2P) tracker. The report found that Trina Solar’s Vertex 210mm bifacial dual-glass module can cut BOS by up to 6.32% and LCOE by 3.72% compared with the 166mm bifacial dual-glass module.


In the report of this third assessment, DNV GL again confirmed the value of Trina’s Vertex modules, being able to maximize value for customers by ensuring minimum LCOE.
Trina Solar is continuing to forge further ahead as a world leader in smart energy and distributed energy solutions involving: PV, energy storage and hydrogen energy industries. We are contributing to the development of a clean, low-carbon, safe and efficient energy system and the development of renewable energy to achieve the goal of carbon neutrality.
