LONGi's BC Technology Achieves Unprecedented Performance in PV Testing

LONGi's Groundbreaking BC Technology Field Data Released

LONGi has made significant strides in the photovoltaic (PV) industry with its groundbreaking Back Contact (BC) technology platform and Hi-MO9 modules. The company has been gearing up for extensive field testing across the globe and has partnered with leading institutions to validate its technology's performance. The recently announced results highlight the remarkable performance levels and reliability the Hi-MO9 modules deliver.

Performance Exceeds Expectations

The global field testing has shown that the Hi-MO9 modules consistently outperform traditional TOPCon modules. Data from diverse geographic locations indicates that these modules deliver stable power generation with impressive watt-for-watt performance. Reports suggest gains ranging from 1.21% to 3.92%, showcasing the cutting-edge efficiency LONGi promises.

European Climate Testing

In one notable assessment conducted in Seville, Spain, by the reputable technical service provider Enertis Applus+, the Hi-MO9 demonstrated its prowess. In the first operational year of a 47MW single-axis tracker PV project, the Hi-MO9 achieved an exceptional 2,209 equivalent full-load hours. Compared to TOPCon modules at the same site, the Hi-MO9 yielded a power generation increase anywhere from 2.4% to 3.4%, which drove down the Levelized Cost of Energy (LCOE) by 3.92% to 4.47%.

Further Validation from IPVF Studies

Additional evaluations by the authoritative institute IPVF across two 50MW ground-mounted PV plants in France and Denmark provided further validation of the Hi-MO9's anticipated performance. The results indicated that performance gains were consistently higher than TOPCon modules, with an average increase of 1.84% in power generation while also lowering LCOE by 3.32% and 2.43% at respective sites.

Ensuring Safety with Hot Spot Management

Another noteworthy feature of the Hi-MO9 modules is their integrated HPBC 2.0 technology, which excels in managing hot spot temperatures. This advanced technology significantly mitigates the risks associated with partial shading. Under typical shading conditions, the Hi-MO9 suppressed the hot spot effect, ensuring temperatures remain well below those seen in conventional modules. This innovative approach can prevent material aging and reduce the likelihood of fire hazards caused by localized overheating, contributing to a reliable operational lifespan of over 25 years.

A Paradigm Shift in Technology Assessment

The comprehensive global field-testing program that LONGi has implemented marks a new standard for evaluating technological value. By utilizing real-world, long-term, and systematic verification methods, LONGi has successfully demonstrated the Hi-MO9's advantages in multiple areas. This thorough approach empowers global customers in the PV sector to make informed decisions based on solid data evidence about technology pathways.
