CHANGZHOU, China – Sep 24, 2025 – At the "All Quality Matters Solar & ESS Congress 2025" hosted by TÜV Rheinland Group in Changzhou, China, LONGi's three modules, Hi-MO 9, Hi-MO X10 Lightweight and Hi-MO X6 Max, based on its advanced BC technology, were honored with the prestigious "Ultra Quality PV Module", " Lightweight PV module "and "PV Module Outdoor Energy Yield “awards. This marks the 9th consecutive years that LONGi has received PV module awards at the "All Quality Matters" event, which continuously confirms its status as an industry benchmark in product technology and quality.
Hi-MO 9: ranked the "Ultra Quality" Top Award
The "Ultra Quality PV Module" award，which was newly introduced on the 2025 "All Quality Matters" event, celebrates the Hi-MO 9's superior product quality and its "zero- weakness" power generation performance.
The "Ultra Quality PV Module" award sets a comprehensive evaluation model—ranging from basic product certification to a "zero-weakness" assessment—crowning the highest standard of product excellence. The award-winning performance of the Hi-MO 9 module stems from LONGi’s self-developed HPBC 2.0 high-efficiency technology. Since its launch, the product has been widely praised by global customers for its exceptional value and has been adopted by international energy leaders such as ENGIE, Nofar Energy, and Yinson for their flagship projects.
Empowered by HPBC2.0 technology, LONGi's Hi-MO 9 module maintains high efficiency even under challenging conditions such as high temperature, humidity, and uneven light exposure. A recent empirical project led by Inner Mongolia Energy Group demonstrated that in an arid, sandy environment with frequent dust storms, the Hi-MO 9 BC module generated 2.45% more electricity per kilowatt and 9.05% more power per unit area compared to TOPCon modules. Particularly during June, which saw frequent cloudy and rainy weather, the BC module consistently outperformed TOPCon every single day, achieving a monthly cumulative generation gain of 2.44% per kilowatt. Further validation comes from international authoritative bodies including Enertis Applus+ and IPVF, which have confirmed through project assessments in Spain and France that Hi-MO 9 offers significant advantages in power output and Levelized Cost of Energy (LCOE) over TOPCon products.
During the event, Mr. Dennis She, Vice President of LONGi, participated in the leader’s forum on photovoltaics and energy storage. He emphasized, "LONGi’s high-efficiency BC technology has undergone large-scale, real-world testing across global markets. The notable power generation gains of BC products deliver higher lifecycle value for customers worldwide, paving the way for a new era of high-quality, sustainable development in the PV industry."
Hi-MO X10 and Hi-MO X6 Max: Success in Distributed Scenarios
In the field of distributed scenario-based applications, LONGi’s high-efficiency BC modules also demonstrated strong competitiveness-winning two Excellence Awards in "Lightweight PV Module" and "Outdoor Energy Yield" simultaneously, further consolidating LONGi’s technological leadership in the distributed market.
Among them, the Hi-MO X10 lightweight module, which won the "Lightweight PV Module" Excellence Award, also equipped with HPBC2.0 technology. While achieving a mass production efficiency of 24.8%, it reduces the weight per unit area to 7.2kg/㎡, a reduction of up to 42% compared with traditional modules. This lightweight advantage not only greatly reduces the load-bearing pressure on roofs, but also effectively cuts down installation man-hours and costs, making it perfectly suitable for various distributed roof scenarios such as residential roofs and C&I color steel tile roofs.
Moreover, the Hi-MO X10 lightweight module has passed TÜV Rheinland’s authoritative evaluations in multiple dimensions, including UV resistance, damp-heat resistance, power generation performance per unit mass, and flame-retardant performance.
Another award-winning product—the Hi-MO X6 Max Anti-dust module, won the "Outdoor Energy Yield" excellence award with its outstanding performance. On the basis of BC’s ultimate conversion efficiency, this product innovatively adopts an anti-dust frame design, which can make full use of rainwater washing to remove dust. This not only significantly reduces the operation and maintenance costs of power plants, but also effectively avoids the "hot spot" phenomenon caused by dust accumulation, ensuring the long-term stable operation of the module.
These two awards not only confirm LONGi’s technological leadership in the distributed product field, but also highlights its accurate insight into end-user needs.
By the end of the first quarter of 2025, the global shipment of LONGi BC modules had exceeded 30GW, which have been widely used in more than 10,000 PV power plants around the world and become the first choice of many leading enterprises and industry benchmark companies.
As a global technological leader in the PV industry, LONGi has provided the industry with a transformation model from "price competition" to "value competition" through the continuous iteration and large-scale application of BC technology. In the future, with the implementation of BC technology in more scenarios, LONGi will further promote cost reduction and efficiency improvement in the global PV industry, inject strong impetus into the realization of the "carbon neutrality" goals, and help accelerate the transformation of the global energy structure.
