Representatives of the independent test laboratory RETC, the world’s leading independent testing organization UL, and the leading global PV and smart energy total solution provider Trina Solar have met to discuss the outstanding advantages of n-type photovoltaic modules.
Representatives talked about the quality, reliability, and performance of Trina Solar’s Vertex N modules. These modules have passed numerous extended reliability tests, including TC, DH, LeTId, PID, and UV, and compound mechanical tests conducted by authorized third parties.
Reliability and performance of Vertex N modules recognized by RETC
The Thresher Test is a series of rigorous tests under durability vetting protocols. Recently Trina Solar’s Vertex N 700 W series and Vertex 580 W series modules turned in an excellent performance to pass RETC’s thresher test.
In an article titled, “Reliability analysis of the n-type module,” Cherif Kedir, the president and chief executive of RETC, explained the result of the thresher test results of Trina Solar’s Vertex modules. In comprehensive reliability and performance tests, RETC found that the performance of Trina Solar’s modules was outstanding. For reliability, Trina Solar’s modules performed well in DH2000, SDML/TC50/HF30, and TC600 tests. In the DH 2000 test, the degradation rates of Vertex N modules were -0.87% and -0.96%, less than -1%. In performance tests, Trina Solar’s modules scored high in LeTId, module efficiency, and PTC.
High energy yield confirmed in UL PAN file test and simulation
PV modules are typically rated at STC. However, solar power plants operate in a range of temperatures, irradiance, and spectra. To ensure the ROI of a solar power plant, accurately forecasting PV module energy yield is critical.
Jason You, a senior project engineer with UL, analyzed the performance advantages of TOPCon PV modules. In making comparisons with p-type modules, UL’s PAN file test of Trina Solar’s Vertex N modules demonstrated that the latter was superior with regard to Pmax temperature coefficients and low-irradiance efficiency.
With the PAN file results, UL conducted a simulative comparison of a 3.1 MW project in three cities: Yinchuan, China, and Jeddah, Saudi Arabia, for high irradiance; and Cologne, Germany, for low irradiance. The tests demonstrated that Vertex N modules’ energy yield was higher than that of p-type modules, 3.96% higher in Jeddah, 3.18% higher in Cologne, and 3.04% higher in Yinchuan.
Golden dimensions Vertex N modules serve customers in many settings
With the newly introduced i-TOPCon advanced technology, Trina Solar boasts cell efficiency in mass production that can reach 26% and module power up to 700 W.
Representatives of Trina Solar gave a presentation on the customer value of the full portfolio of Vertex N all-scenario solutions. By integrating what has been called the golden dimensions concept with n-type i-TOPCon advanced technology, Trina Solar’s Vertex N modules can be applied in numerous settings, including utility-scale solar plants, commercial and industrial (C&I) installations, and residential rooftops.
Vertex S+ is the perfect choice for residential rooftops because it achieves the highest power output of 450 W within 2 square meters. With the golden dimension design, Vertex N 605 W modules maximize the use of container space, with the utilization rate reaching 98.5% in a 40-foot-high cube container, delivering customers lower balance-of-system (BOS) costs.
To meet the increasing demand for high-power and n-type modules, by the end of the year, Trina Solar’s module production capacity is forecast to reach 95 GW and its cell production capacity 75 GW, with 40 GW dedicated to n-type cells. With the leading n-type i-TOPCon technology, golden dimensions concept, and all-scenario highly reliable and high-performance Vertex n-type products, Trina Solar will maintain its leading position in the era of n-type technology.
