LONGi Global BC Technology Field Data

In an impressive update, LONGi has announced the global field performance results of its innovative Back-Contact (BC) technology platform and its HI-MO9 module. This news comes after extensive collaboration with international clients and renowned independent institutions. Following the launch of the BC technology, LONGi initiated a systematic global field testing program. The results indicate that the Hi-MO9 module exhibits a level of stability and consistency that surpasses expectations in terms of actual power generation, economic benefits, and environmental sustainability.

Comprehensive Testing Results

Reports from several highly respected international technical service organizations reveal that LONGi's BC modules generate a robust increase in performance per watt compared to conventional TOPCon modules, with improvement rates ranging from 1.21% to 3.92%. Notably, in certain scenarios, the performance gains are particularly striking. For instance, in a review conducted by Enertis Applus+, a leading European technical service provider for a 47-MW PV project featuring single-axis tracking systems in Seville, Spain, the Hi-MO9 achieved 2,209 equivalent full-load hours in its first operational year. The watt-for-watt power generation outperformed TOPCon modules at the same site by 2.4% to 3.4%. Comprehensive calculations demonstrate that the Levelized Cost of Energy (LCOE) could be reduced by 3.92% and 4.47%, respectively.

Further evaluation projects overseen by the prestigious IPVF institute confirmed the stability of the Hi-MO9's performance gains. An analysis of operational data from two 50-MW ground-mounted PV power plants in France and Denmark revealed that Hi-MO9's watt-for-watt power generation averaged 1.84% higher than that of TOPCon modules, while the LCOE was 3.32% and 2.43% lower than its counterparts.

Enhanced Safety Features

Besides significant improvements in power generation, the integrated HPBC 2.0 technology within the Hi-MO9 module delivers additional value through its exceptional performance during low hotspot conditions. Field data reveal that under typical partial shading situations, the Hi-MO9 effectively suppresses the hotspot effect, maintaining substantially lower hotspot temperatures than traditional modules. This reduction critically mitigates risks associated with material aging, performance degradation, and even potential fire hazards caused by local overheating, offering a robust assurance for reliable plant operation over 25 years.

A New Paradigm for Technology Assessment

LONGi's global field testing program for the Hi-MO9 represents a novel paradigm for evaluating technological value based on real, long-term, and systematic reviews. The results clearly demonstrate the multifaceted advantages of the Hi-MO9 regarding increased power generation, LCOE management, and environmental compatibility. This milestone indicates a significant step towards the broader application of BC technology, providing PV customers worldwide with a factual basis for technology path evaluations.
