Solar Research Institute In Europe Verifies Superior Performance Ultra High-Power Modules


Reading Time: 4 minutes

The Fraunhofer Institute for Solar Energy Systems (Fraunhofer  ISE) in Germany has presented a series of studies on ultra high-power modules made by Trina Solar and other manufacturers.  


Fraunhofer ISE did a comparative study on the levelized cost of energy (LCOE) of Trina Solar’s  550W, 600W and 670W ultra-high-power modules as compared to M10 and M6 modules.  

M10 refers to modules that use solar cells that are 182mm in diameter. M6 refers to modules that use solar cells that are 166mm in diameter. The new industry standard is 210mm diameter solar cells. Trina Solar’s 550W, 600W and 670W ultra-high-power modules use 210mm diameter solar cells.  

At a recent conference, Fraunhofer ISE project manager for modules and power plants analysis,  Jefferson Bor, presented the results of the comparative study.  

The results reveal that new generation modules, that use 182mm and 210mm diameter solar cells, have greater advantages in system value as compared to solar modules that use 166mm diameter solar cells.  

As for modules that have 210mm diameter solar cells, the advantage is these modules have low voltage and high string power. This creates a greater advantage with regards to capital expenditure  (CAPEX) and LCOE as compared with 182 series on both fixed-tilt and trackers.

Compared with 585W M10 modules, Trina Solar’s 600W and 670W Vertex modules, which use 210  series solar cells, have excellent performance with savings on CAPEX of 1.5-2 €cWp and 3 – 4.5%  on LCOE.  

Compared with 455W M6 modules, the savings on LCOE is 7.4%. The 210 modules represented by  Trina Solar’s Vertex 670W, 600W and 550W provide more value to customers. 

With the advancement of PV power parity, LCOE and CAPEX have become the focus of investors. 

Trina Solar’s Vertex ultra-high-power modules satisfy the global PV market demand and are driving momentum for further development in the PV industry.

At the same conference, Trina Solar executives also gave presentations.  

Dr. Zhang Yingbin, head of product strategy and marketing at Trina Solar gave a speech entitled The  600W+ Solar Module Market, Ecology System Construction and Industrialization.  

Zhang says the ecosystem of 210 modules has already been formed, and 210 modules are fully compatible with mainstream inverters and trackers. The inverters solutions apply to all the scenarios of residential, commercial and industrial, and utility-scale power projects that are installed with 210 modules. In addition, compared with the industry level, Trina Solar’s Vertex modules have an increase of 35W-90W in power and a save on BOS at $0.5-1.6 cents per watt, contributing to more value for customers.

Also, Trina Solar senior manager for global module product, Gao Lei, gave an in-depth analysis of  the reliability of 670W Vertex modules.

Trina Solar 670W Vertex modules have passed six mechanical loading tests with excellent  mechanical load capability and the reliability is fully verified, he says. In the rigorous tests that  simulate extreme weather conditions such as extreme wind, snowstorm, extreme cold and hail, the  test result of 670W Vertex modules is far above IEC standards, he adds.
