to the development of more advanced accelerated testing methods. One of our latest innovations is the HF+UV testing system, which combines climate chamber testing with ultra- violet exposure in a single platform. Compared with conventional testing methods, this integrated approach significantly accelerates reliability evaluation and enables manufacturers to assess multiple degradation mecha- nisms more efficiently. Q Your equipment supports international standards such as IEC, UL and BIS. How important is testing standardisa- tion in building confidence among investors and project devel - opers? Dr. Zhigang Liu: Testing standards are extremely important because they provide confidence that products will perform reliably over their intended lifetime. For investors and project developers, long-term energy gener- ation determines project returns. If modules degrade faster than expected, investment performance is directly affected. Independent testing based on internationally recognised standards helps manufacturers demonstrate product reliabil- ity and enables customers to make informed purchasing de- cisions. Q What were the key testing technologies showcased by Zealwe Tech at SNEC this year? Dr. Zhigang Liu: Our key highlight at SNEC was the HF+UV testing system. In addition to supporting conventional IEC qualification testing, this platform enables combined testing such as HF, TC, DH, UV, HF+UV, TC+UV and DH+UV within a single system. The product attracted considerable interest because it offers faster and more comprehensive reliability evaluation, helping manufacturers shorten validation cycles while maintaining high testing accuracy. Q India is placing greater emphasis on domestic manu- facturing, product quality and traceability. How can ad- vanced testing solutions help Indian manufacturers remain globally competitive? Dr. Zhigang Liu: Cost competitiveness is important, but sus- tainable competitiveness comes from delivering reliable prod- ucts. Manufacturers must optimise costs without compromis- ing quality. Advanced testing allows manufacturers to select the right materials, optimise production processes and verify product performance before large-scale deployment. This helps them produce modules that are both cost-effective and highly re- liable, strengthening their competitiveness in both domestic and international markets. Q Through your collaboration with Aster E Technologies, how are you helping Indian manufacturers establish world-class testing laboratories? Dr. Zhigang Liu: We have worked closely with Aster E Tech- nologies for many years to support India’s growing PV man- ufacturing industry. Together, we provide not only advanced testing equipment but also comprehensive services, including installation, commissioning, training and technical support. This partnership enables Indian manufacturers to estab- lish testing laboratories quickly and efficiently. During the COVID-19 period, when international travel was restricted, Aster E Technologies’ local service capabilities ensured cus- tomers continued to receive timely support. This local pres- ence has played an important role in helping Indian manu- facturers strengthen their quality assurance capabilities and build globally competitive production facilities.
