The beginning of summer brings not only scorching sun and cicada songs but also the most prestigious solar energy event in the industry. On June 13th, the 17th(2024) International Photovoltaic Power Genaration and Smart Energy Conference and Exhibition (hereinafter referred to as “SNEC”) grandly opened at the Shanghai National Convention and Exhibition Center. Gand Sunergy unveiled a range of new photovoltaic products, attracting the most powerful industry partners and clients for exchanges. The immense popularity at the booth highlights Grand Sunergy’s relentless pursuit of high-efficiency photovoltaic conversion technology and its firm determination to provide powerful momentum for a zero-carbon society.
01
High-Efficiency Products
Officially Unveiled at SNEC
As a representative of China’s “new engine” for economic growth and “new trio” of foreign trade exports, photovoltaics have become a highly certain and prosperous pillar industry for China’s future. This exhibition attracted over 500,000 professional visitors, more than 5,000 photovoltaic academic experts, and over 3,100 domestic and international photovoltaic exhibitors, showcasing the industry’s high recognition of photovoltaic development prospects.
At this globally significant photovoltaic event, Grand Sunergy showcased newly upgraded products, including the Eutropic Series 182-108 Super All-Black HJT Module, the 182-144 Single Glass HJT Module, the Chasing Series 210-132 Ultra-High Power HJT Module, the 210-132 SeaPower HJT Offshore Module, and the new Expedition Series 210R-132 Rectangular Cell HJT Module, demonstrating the company’s leading product development capabilities in the N-type HJT field.
Grand Sunergy’s Chasing Series 182-108 Super All-Black HJT Module features the new generation 0BB busbar-less module technology, integrating black high-reflective film, specially-made black ribbon, and black busbar. From the film, ribbon, busbar, and cells to the module’s outer frame, the overall visual effect is a glossy black. The module uses aesthetically pleasing double-coated glass with anti-glare properties. Compared to the previous generation, it redefines the aesthetic appeal of all-black modules. Additionally, the module’s welding employs pre-glued adhesive bonding instead of traditional hot soldering, preventing hidden cracks due to uneven thermal expansion. This product boasts a maximum power of 450W and an efficiency of 23.02%, providing extreme aesthetic appeal while offering higher power output and lower risk of hidden cracks, making it highly favored by overseas distributed users.
To address the issue of low-load roofs unsuitable for dual-glass modules, Grand Sunergy’s R&D team specially developed the lightweight single-glass HJT module – Chasing Series 182-144 Single Glass HJT Module. This product reduces weight by 20%-30% compared to conventional dual-glass modules, making it more suitable for roof load-bearing. This feature effectively reduces the cost per watt in scenarios involving high labor and logistics costs, resulting in lower overall LCOE. The backsheet’s high reflectivity design enhances the module’s front power, with a maximum power of 610W and an efficiency of 23.61%, leading to higher power generation per unit area. Additionally, the module’s front side uses fully tempered glass, providing better resistance to breakage and hail, and the backsheet uses high water-resistance encapsulation with waterproof sealing materials, perfectly solving the waterproofing challenges of single-glass products, tailored for single-sided roof markets like steel roofs.
At the exhibition, Grand Sunergy Expedition Series 210R-132 Rectangular Cell HJT Module features HJT-210R rectangular cells, with module dimensions of 2382mm x 1134mm, representing a new breakthrough in module design and system optimization. The maximum power is 640W, with an efficiency of 23.69%. The rectangular silicon wafer design increases the effective power generation area compared to conventional 182mm sizes, further enhancing power generation per unit area. In the supply chain, the rectangular size maximizes container space utilization, improving logistics efficiency with a utilization rate of up to 98.5%. On the system side, higher power generation and a 90% ultra-high bifacial rate ensure better power performance and higher power gains for power plants, effectively reducing the cost of electricity and significantly improving the return on investment ratio.
Chasing the light, continuously moving forward, Grand Sunergy relentlessly explores the boundaries of photovoltaic application and efficiency breakthroughs. Through accumulated process stacking and capacity ramping, the Chasing series 210-132 model ultra-high power HJT modules continually enhance efficiency. Certified by global third-party authoritative testing institutions, the maximum power of the modules has broken through 751.24W, with an efficiency of 24.18%. These products use 210mm large-size high-efficiency HJT cells and 0BB busbar-less technology, combined with impurity reduction and bifacial microcrystalline processes to reduce internal defects and impurities in cells, effectively enhancing light absorption and conversion. Additionally, by eliminating the main busbar on the cell end, silver consumption is reduced by over 30%. In the packaging phase, busbar-less welding technology is employed, utilizing finer and more numerous low-temperature solder wires for current collection, enhancing conductivity. The finer ribbon also enhances the product’s aesthetics. The product features no PAD point obstructions, and is equipped with custom-developed double-coated glass, light conversion film, and gap film technologies, making it a truly ultra-high power module.
The Grand Sunergy Chasing series 210-132 model SeaPower HJT offshore module is specifically developed for marine and tidal flat application scenarios. The product frame is made from polyurethane polymer composite material, which is durable and corrosion-resistant, capable of stable operation in high salt fog and high alkaline environments, and mechanically robust enough to withstand category 16 typhoons, making it an unparalleled choice for marine applications. These modules incorporate water-resistant butyl rubber edging, offering excellent air tightness and water vapor resistance, enhancing water resistance by two orders of magnitude, allowing for stable operation in high temperature and humidity environments, effectively extending the module’s lifespan. Furthermore, the SeaPower HJT modules incorporate a light conversion film design and are equipped with a new generation of highly sealed junction boxes and connectors, ensuring product durability against UV exposure, water vapor, and salt mist corrosion, while significantly enhancing module power output.
