LONGi has announced the global field performance results of its Back Contact (BC) technology platform and Hi-MO 9 module. Following the launch of the technology, the company initiated a systematic global field testing program across multiple key markets. In collaboration with global customers, third-party organisations and its own testing bases, the company conducted long-term  comparative monitoring of power generation performance across diverse climates and typical application scenarios in China, Europe, the Middle East, Asia-Pacific and Latin America.<\/p>\n\n\n\n

The extensive testing network covered a range of typical and harsh environments\u2014including temperate continental, tropical, arid regions and high-humidity coastlines\u2014to evaluate the Hi-MO 9 module\u2019s performance under real-world operating conditions beyond standard laboratory settings. Global field data demonstrate that the product exhibits stability and consistency exceeding expectations in actual power generation performance, system economic benefits and environmental adaptability.<\/p>\n\n\n\n

An assessment conducted by European technical service provider Enertis Applus+ for a 47 MW single-axis tracker PV project in Seville, Spain, showed that the Hi-MO 9 achieved 2,209 equivalent full-load hours in its first operational year, with watt-for-watt power generation 2.4% to 3.4% higher than other module types at the same site. Comprehensive calculations indicate that its Levelized Cost of Energy was reduced by 3.92% and 4.47%, respectively, compared with other mainstream modules, delivering direct economic value to investors.<\/p>\n\n\n\n

In Northern and Western Europe, evaluation projects led by the IPVF institute further validated the stability of the product\u2019s performance gains. Analysis of operational data from two 50 MW ground-mounted PV power plants in France and Denmark indicated that the Hi-MO 9\u2019s watt-for-watt power generation was on average 1.84% higher than that of other modules, while the LCOE was 3.32% and 2.43% lower than that of these equivalents.<\/p>\n\n\n\n

Under China’s diverse climatic and geographical conditions, the Hi-MO 9 also demonstrated excellent power generation performance. In the high-temperature, high-humidity environment of Sanya, Hainan, assessment by China\u2019s General Certification Center confirmed that the Hi-MO 9 achieved a 1.54% watt-for-watt power generation gain over equivalent modules, with a backsheet operating temperature 1.21\u00b0C lower and a 0.19 percentage point advantage in power degradation rate over six months. At the Sanmen tidal flat test site in Zhejiang, its power generation gain reached 1.87%, with temperature and degradation rate advantages of 1.26\u00b0C and 0.38%, respectively. At an offshore high-humidity test base in Shandong, the CPVT National PV Product Quality Inspection Center verified the Hi-MO 9\u2019s outstanding performance in high-temperature stability, low-light response, and long-term reliability.<\/p>\n\n\n\n

The value of the HPBC 2.0 technology integrated into the Hi-MO 9 lies not only in significant power generation gains but also in its revolutionary low hot spot performance. Field data show that under common partial shading conditions\u2014such as those caused by vegetation, bird droppings, dust or structural shadows\u2014the Hi-MO 9 effectively suppresses the hot spot effect, with hot spot temperatures significantly lower than those of conventional modules. This technological breakthrough elevates PV plant safety to a new level. Lower hot spot temperatures fundamentally mitigate risks of material aging, power degradation and even potential fire hazards caused by localized overheating, providing a solid guarantee for reliable plant operation over 25 years. Whether in residential rooftop scenarios with stringent safety standards, large-scale ground-mounted power plants with high maintenance demands, or even complex hybrid wind-solar applications, LONGi’s BC technology has been verified as an ideal solution that simultaneously delivers high power generation returns and ultimate safety.<\/p>\n\n\n\n

LONGi’s global field testing program for the Hi-MO 9 represents not merely a presentation of power generation data, but a new paradigm for assessing technological value based on real-world, long-term and systematic verification. The results fully demonstrate the Hi-MO 9\u2019s comprehensive leading advantages in power generation gain, LCOE control, and environmental adaptability, marking a significant milestone in the further large-scale application of BC technology and providing global PV customers with a clear, fact-based decision-making basis for evaluating diverse technology pathways.<\/p>\n\n\n\n
