Production Chain



IREX has concentratively invested in research & development. Thus, we always satisfy the highest demands for standards, quality in both domestic and globals markets. In terms of technology, we actively research the latest technologies, techniques to apply it into local environmental conditions at every installation areas to enhance the quality of solution. Therefore, IREX is proud to be a Vietnamese enterprise that has successfully applied the new technologies in producing, such as Multi-busbar, PERC, Anti-PID, etc.

In addition, R&D has also succeeded in researching on the change of internal and external structure of Solar cell, such as increasing Solar cell technology from 3,4 to 5 busbar. Besides, Successful researching and application of the new technology also helps to counteract the diffusion of electrons and increase the energy conversion efficiency of the IREX solar panels by approximately 3% to reach 20% compared with Mono-Crystalline Silicon Battery Series.

In terms of solution, we researched to apply the globalization technology trends: Internet of Thing (IoTs), Big Data, Artificial Intelligence (AI) to IREX’s solar power solution. Moreover, IREX has flexibly developed the solutions which are intergrated with advanced technologies satisfying the unique need of each customer. From success on researching and developing Belink controllers, a smart device used for collecting data from solar systems, our R&D team has upgraded it to SSOC™ that allows customers monitor and control online energy systems. Apart from that, SSOC™ can be customized to fulfill particular needs of customers. This is a special feature thanks to the full control of technology of IREX.
