Global Experts Recogize Trina Solar’s Bifacial 600W+ Modules for Value, High Reliability, and Remarkable Energy Gain Performance

Efficient and reliable ultra-high power bifacial dual-glass modules significantly boost energy yields and create more value for end customers. At a recent virtual conference titled “Bifacial & Solar Trackers – Boosting Solar Power Plant Yields,” industry experts discussed the empirical data from multiple field tests in different environments showing higher energy produced by Trina Solar’s bifacial Vertex ultra-high power modules. Trina Solar has now shipped 20GW+ of bifacial dual-glass modules to deliver this added value for end customers.

Optimizing Project Design for Best Bifacial Modules Energy Gain

Compared with mono-facial modules, ultra-high power bifacial modules generate higher power output because total power generation comes from both the front and rear sides of the module. However, the backside power generation depends on the bifaciality and the irradiation that reaches the other side of the panel. Backside irradiation is affected by various factors, including environment, project design, and the ground’s surface condition. In Trina’s empirical study, researchers conducted analyses on three main factors: albedo latitude, scattered light, and the mounting height’s (elevation) contribution to the energy yield of bifacial modules. Higher albedo, higher latitude, more scattered lights, and higher elevation normally contribute to more considerable yield gain. 

Bifacial 210 Vertex Module Boosts Energy Yield Efficiently in Various Environments

The cases presented at the conference included three ground types: grass, flat gravel floor, and sand. Third-party institutes assessed the studies demonstrating higher energy yield of Trina Solar’s bifacial Vertex 600W+ modules. 

Bifacial 670W+ modules in Hainan, China, tested by TÜV Rheinland, were installed on grass at a latitude close to tropical. The field data showed that the power generation of the 210 bifacial module was about 6.1% higher per watt than that of a reference 210 mono-facial module.

In Cologne, Germany, TÜV Rheinland tested the same modules on gravel. Due to the higher latitude, higher scattered light, and advantages in low irradiation, the power generation of the 210 bifacial Vertex module was more than 8.6% higher per watt than that of the reference 210 mono-facial module.

In Yinchuan, China, CPVT tested bifacial Vertex modules installed on sand at a medium latitude. The power generation of the 210 bifacial module was more than 10.51% higher per watt than that of the reference 210 mono-facial module.

In addition to all these tests, Trina Solar has conducted other empirical studies on grass, sand, white substrate, and cement, all showing that the bifacial module has realized considerable gains and significantly reduced energy costs.

210 Bifacial Module’s Excellent Reliability 

Trina Solar’s 210 bifacial module demonstrates superior reliability in several aspects. 

First, the structure of the bifacial module requires replacing the standard solid backsheets with glass. Double glass encapsulation provides additional protection to embed solar cells due to its excellent reliability and durability through high resistance to five aging factors caused by nature: alkaline, acidic, high temperature, high humidity, and UV.

Moreover, superior reliability, including an extended product warranty (upgraded to 30 years), lower degradation (P-PERC 2% first year, 0.45% annually), and excellent bifaciality (P-PERC: 70% ±5%, N-type: 80% ±5%) also contribute to greater energy yield. 

Independent testing organizations such as RETC and PVEL endorsed the performance and reliability of the 210 bifacial modules. Last month, RETC recognized the company as an Overall High Achiever for its 670W series modules’ superior reliability, performance, and quality. Earlier, PVEL named Trina Solar a Top Performer for the eighth year in a row, highlighting Trina Solar’s commitment to excellent quality consistency, high reliability, and outstanding safety of its modules. 

Superb Value of Bifacial Modules: Lower LCOE

As a result of significantly higher energy gain and reliability, Trina Solar’s Vertex 210 bifacial modules contribute to lower LCOE. At the recent conference, Trina Solar presented the results of a virtual 50MW project assessment in Spain (latitude: 37.25º N, longitude: -5.87º W, altitude: 60 m, GHI: 1850.3Kwh/m2, DiffHor:597Kwh/m2) showing that bifacial modules can reduce LCOE by 1.93% in a fixed-tilt system, and by 2.26% in a solar tracker system. 

Higher energy yield and lower LCOE prove the tremendous value of bifacial modules. Trina Solar has always been committed to creating better value for its global customers through our relentless efforts to advance technology and product innovation.
