Suntech and HY Solar have jointly showcased their latest PV and energy storage technologies at SNEC PV+ 2026, presenting an integrated portfolio spanning silicon materials, wafers, solar cells, modules and energy storage systems.
Through their combined capabilities across manufacturing, technology development and global market deployment, the two companies highlighted a vertically integrated platform designed to support the evolving needs of utility-scale, commercial and residential energy projects.
Among the key highlights at the exhibition was the debut of Suntech’s Ultra T 3.0 quarter-cut module, built on the latest TOPCon 3.0 cell technology.
With a cell conversion efficiency exceeding 27.5%, the module delivers bifaciality of up to 90%, helping maximize energy yield in a wide range of installation environments. The product is designed with a first-year degradation rate of no more than 1% and annual linear degradation as low as 0.35%, supporting long-term performance throughout the project lifecycle.
The quarter-cut architecture reduces operating current and electrical losses, while improving heat dissipation and hotspot resistance. Combined with dual-glass construction and advanced encapsulation technology, the module is engineered to deliver reliable performance under demanding environmental conditions, including high temperatures, humidity, salt mist and dust exposure.
The Ultra T 3.0 platform represents the latest milestone in Suntech’s N-type technology development roadmap and is designed to support lower LCOE across both utility-scale and distributed solar projects.
The company also showcased a range of module solutions tailored to the requirements of utility-scale, commercial and residential projects.
For utility-scale projects in regions affected by dust and sand accumulation, it presented a 650W anti-soiling module featuring an optimized frame structure and surface treatment technology designed to reduce dust build-up and lower maintenance requirements over the lifetime of a project.
For residential rooftops, commercial buildings and BIPV applications, it presented a 470W anti-glare module with a full-black design. The product incorporates specialized optical treatment to reduce reflected glare while maintaining architectural aesthetics, making it suitable for urban and premium residential installations.
Energy storage was another major focus of the joint exhibition.
Suntech showcased its SunStorage product portfolio, covering residential, commercial and industrial applications, the lineup including residential storage systems ranging from 4kW to 20kW with stackable high-voltage battery configurations, as well as a 125kW/261kWh commercial and industrial storage cabinet designed for peak shaving, backup power and energy management applications.
The company also introduced a 125kW DC-coupled hybrid inverter that enables tighter integration between photovoltaic generation and energy storage systems, supporting higher overall system efficiency and optimized project economics.
During the event, Suntech and HY Solar jointly demonstrated capabilities spanning the entire PV value chain, from silicon materials and wafer manufacturing to high-efficiency cells, modules and energy storage solutions.
HY Solar contributes vertically integrated manufacturing expertise across upstream and midstream PV production, with Suntech bringing more than two decades of global market experience, established international distribution channels and localized customer support capabilities.
By combining their respective strengths, the two companies aim to enhance supply chain coordination, accelerate the deployment of N-type technologies and deliver integrated clean energy solutions to customers worldwide.
