继去年12 月初，国内外领先设计院和权威第三方机构DNV GL对天合至尊系列组件系统成本和度电成本进行首轮测算后，2021年1月，DNV GL再次进行第二轮针对600W+至尊双面双玻平单轴双排竖装2P跟踪系统价值进行全场景的度电成本优势和收益测算。本次测算地址选择在具有地理代表性的西班牙和美国两座电站。DNV GL测算报告显示，天合光能210至尊双面双玻组件较166mm双面双玻组件可节省BOS高达6.32% ，对应度电成本降幅达3.72％。

▎天合210组件及跟踪系统价值持续提升

在光伏行业全面加速进入平价时代的背景下，天合光能持续致力于降本提效，先进210组件和至尊系列产品的度电成本优势更为突显。在去年12月初，DNV GL对天合光能210至尊系列545W双面双玻组件单排竖装1P与传统166mm双面双玻450W组件、182mm双面双玻535W组件进行系统成本测算，评估结果表明210组件BOS优势明显，度电成本（LCOE）更优，降幅达3.5%。（最佳度电成本之道系列报道（一）| DNV GL权威解读600W+至尊双面双玻平单轴跟踪系统价值）

此次《DNV GL权威解读600W+至尊双面双玻平单轴跟踪系统价值系列报道（二）》针对双排竖装2P跟踪系统的测算结果，再次肯定天合光能至尊组件的系统价值。至尊组件创新的低电压、高串功率设计，使得单串组件功率显著提高，同时有效降低各个环节，进一步降低初始投资。

▎测算项目：BOS成本节约达 6.32% ，度电成本降幅达3.72％

此次双排竖装2P平单轴跟踪测算，项目地选取在欧洲西班牙，美国德克萨斯典型光伏电站项目应用地区，地点经纬度坐标及气候条件如下：

以上述两个地点作为测算项目地，DNV GL分别测算210至尊系列双面双玻545W组件在双排竖装2P跟踪支架系统下，对比166mm 双面双玻450W组件及182mm双面双玻535W组件的系统成本BOS及度电成本LCOE。测算项目固定为100MW AC容量，相同DC/AC 比值设计电站，使用主流双排竖装平单轴（2P）跟踪支架，配套主流组串式逆变器。系统设计中固定地面覆盖率（GCR，Ground cover ratio)，保证双面组件的双面应用阴影遮挡影响的一致性。

上述设计旨在控制同地点外部因素影响、系统配置，客观对比测算不同类型组件对于系统造价及度电成本的差异影响。在测算中针对两个项目地址，三种组件的成本对比都采用了当地设备、建安、人工造价、上网电价、运维成本、土地成本、财务成本等一致的条件，确保成本测算的完整及客观。

▎测算结果

西班牙项目地测算结果：

天合光能210至尊双面双玻545W组件较166mm双面双玻 450W组件可降低BOS约6.32％，对应度电成本LCOE降幅约3.19％，较182mm双面双玻 535W组件节省BOS近1％，且度电成本LCOE更优。

美国项目地测算结果：

天合光能210至尊双面双玻 545W组件较166mm双面双玻 450W组件可节省BOS约6.06%，对应度电成本降幅约3.72％，较182mm双面双玻 535W组件节省BOS约1.2%，相对应度电成本节省约0.5％。

▎DNV GL 报告再证：天合提升单串功率、降低多项成本、LCOE度电成本最低

继单排竖装1P跟踪测算之后，第三方DNV GL对双排竖装2P跟踪系统的测算结果，再次肯定了天合光能至尊组件的系统价值。首先，至尊组件创新的低电压、高串功率设计，使得在1500V系统电压下得以串联更多的组件，显著提高单串功率；同时，超高的单块组件功率，可以减少项目组件使用总块数，组串数量降低带来的直流线缆材料成本的节省，同时有效降低运输、人工安装及支架等成本，进一步降低初始投资。最后，加持至尊组件优异的发电性能，确保LCOE度电成本最低，实现客户价值最大化。

天合光能成立23年以来，一直以创新、可信赖的品质和客户价值驱动发展。自2020年2月发布首款先进210组件，今天已演化出包括400W至尊小金刚，500W、550W和600W至尊系列等丰富的产品线，覆盖户用、工商业、常规地面电站以及与农光、渔光等应用场景。天合光能在2021年底光伏组件产能规划不低于50GW，未来将继续夯实基于大尺寸电池的先进组件产能规模优势。

In early December, a leading domestic and foreign design institutes and authoritative third-party institutions DNV GL to TRW sovereign series component system cost and KWH cost calculates the first round, in January 2021, DNV GL again for a second in 600 w + the supreme double double glass flat uniaxial double row with 2 p vertical tracking system value for the whole scene of KWH cost advantage and earnings estimates. This time, two geographically representative power stations, Spain and the United States, were selected as the location of the calculation.DNV GL measurement report shows that Trina Solar 210 supreme double-sided double-glass module can save BOS up to 6.32% compared with 166mm double-sided double-glass module, and the corresponding cost per kilowatt hours can be reduced by 3.72%.

App of Trinda 210 components and tracking system continues to increase

As the PV industry accelerates its entry into the era of parity, Trina Solar continues to reduce costs and improve efficiency. The cost per kilowatt hour advantage of the advanced 210 modules and the Supreme series of products is more prominent. In early December of last year, DNV GL calculated the system cost of Trina Solar 210 Supreme Series 545W double-sided, double-glass single-row vertical 1P versus the traditional 166mm double-sided, double-glass 450W and 182mm double-sided, double-glass 535W. The evaluation results showed that the 210 BOS had significant advantages and the cost per kilowatt hours (LCOE) was better, with a decrease of 3.5%.(the way of best KWH cost series (a) | DNV GL authoritative interpretation of 600 w + the supreme value double double glass flat uniaxial tracking system)

This "DNV GL Authoritative Interpretation of 600W+ Ultimate Double-sided Double-glass Flat Single Axis Tracking System Value Series (2)", based on the measurement results of the Double-row Vertical 2P Tracking System, reaffirmed the system value of Trina Solar Ultimate. The innovative low voltage and high series power design of the supreme component significantly improves the power of the single series component and effectively reduces all links, further reducing the initial investment.

App introduction: cost saving of BOS at 6.32%, per day cost reduction at 3.72%

The project location is selected in typical application areas of PV power station projects in Europe, Spain and Texas of the United States. The location's longitude and latitude coordinates and climatic conditions are as follows:

Using the above two locations as the measurement project, DNV GL measured the system cost BOS and kilowatt hours (kWh) of the 210 supreme series double-sided double-glass 545W component and compared the 166mm double-sided double-glass 450W component and the 182mm double-sided double-glass 535W component under the double-row vertical 2P tracking bracket system. The calculation project is fixed at 100MW AC capacity, the same DC/AC ratio design power station, using the mainstream double-row vertical flat single axis (2P) tracking bracket, supporting the mainstream group series inverter. The fixed Ground cover ratio (GCR) in the system design ensures the consistency of shadow shielding effect of double-sided applications of double-sided components.

The above design aims to control the influence of external factors and system configuration at the same location, and objectively compare and measure the difference influence of different types of components on the system cost and kilowatt-hour cost. In the calculation of the two project addresses, the cost comparison of the three components adopts the same conditions of local equipment, construction and installation, labor cost, on-grid price, operation and maintenance cost, land cost, financial cost, etc., to ensure the integrity and objectivity of cost calculation.

App measurement results

Calculated results of the project in Spain:

Trina Solar 210 supreme double-sided dual-glass 545W module can reduce BOS by 6.32% compared with 166mm double-sided dual-glass 450W module, corresponding to a decrease of 3.19% in the cost per kilowatt (kWh), save BOS by nearly 1% compared with 182mm double-sided dual-glass 535W module, and the cost per kilowatt (kWh) is better.

Calculated results of the US project:

Trina Solar 210 supreme double-sided dual-glass 545W module can save about 6.06% BOS compared to 166mm double-sided dual-glass 450W module, which is about 3.72% lower in cost per kilowatt hour. It can save about 1.2% BOS compared to 182mm double-sided dual-glass 535W module, which is about 0.5% lower in cost per kilowatt hour.

▎DNV GL Report Revisit: This App promotes single battery power, reduces many costs, and has the lowest electricity cost for your LCOE

Following the single-row vertical 1P tracking measurement, the third party DNV GL's measurement of the double-row vertical 2P tracking system confirmed the system value of Trina Solar SUI. First of all, the innovative low voltage, high series power design of the supreme component enables more components to be connected in series under the 1500V system voltage, significantly increasing the single series power; At the same time, the ultra-high power of single component can reduce the total number of components used in the project and the reduction of the number of clusters, which can save the cost of DC cable material, and effectively reduce the cost of transportation, manual installation and bracket, and further reduce the initial investment.Finally, the superior power generation performance of the Supreme module ensures the lowest cost per kilowatt hour of LCOE and maximizes customer value.

Since its establishment 23 years ago, Trina Solar has been driven by innovation, reliable quality and customer value.Since the release of the first advanced 210 component in February 2020, today, it has evolved into a rich product line including 400W Supreme Little King Kong, 500W, 550W and 600W Supreme Series, covering household, industrial and commercial, conventional ground power stations, as well as agricultural light, fishing light and other application scenarios. By the end of 2021, Trina Solar plans to have a production capacity of no less than 50GW of photovoltaic modules. In the future, Trina Solar will continue to consolidate its advantage in the production capacity of advanced modules based on large-size batteries.
