World’s Largest BC PV Project Secured! TCL Solar Awarded Australia Module Order
On July 29 in Melbourne, Australia, TCL Solar successfully secured a PV module order from DT Infrastructure (DTI) to supply the complete set of PV modules for two solar power plants—Smoky Creek and Guthrie’s Gap—developed by Edify Energy in Central Queensland, Australia. Construction and installation are expected to officially launch in early Q2 2027. With a total capacity of 720 MW, the project will set a new industry record upon completion as the world’s largest utility-scale PV power plant utilizing Back Contact (BC) technology.
The project will exclusively use TCL’s BC modules, which feature a maximum conversion efficiency of up to 24.2%, backed by a 15-year product warranty and a 30-year performance warranty.
Frank Zhang, Director of SunPower Australia and President of International Business at TCL Solar’s Global Marketing Center, stated that securing this 720 MW mega-order marks not only a major development milestone for TCL Solar, but also a crucial breakthrough for BC technology in utility-scale solar applications. While BC technology has historically been used primarily in the premium residential market, this ultra-large project demonstrates that high-efficiency BC modules deliver exceptional product value in large-scale PV projects. Leveraging a mature local Australian team established in 2008 and full supply-chain support from TCL Zhonghuan’s headquarters, the team will ensure on-time module delivery and smooth project execution in close collaboration with DT Infrastructure.
Adam Farquer, Project Director at DT Infrastructure, expressed high expectations for the partnership. He noted that executing large-scale renewable energy projects relies on supply chain collaboration and that this project serves as a prime demonstration model for applying high-efficiency BC technology to utility-scale plants. Both parties will work together to build a benchmark PV engineering project.
Over the years, TCL SunPower has validated the large-scale application of BC technology through landmark projects, accumulating extensive global market experience. Previously, the 579 MW Solar Star PV plant in California, USA, and the 349 MW Limondale PV plant in Australia were both constructed using SunPower’s high-efficiency BC modules. At their respective commissioning times, they ranked as the largest PV power plants globally and in Australia, fully proving the feasibility and superiority of BC technology in utility-scale scenarios.
Located in Central Queensland, the two power plants enjoy a strategic geographic location and form a highly representative mega renewable energy complex in Australia. Developed by Edify Energy, the project integrates large-scale PV power generation with advanced energy storage systems. Once fully operational, the project will generate an average of 1,589,000 MWh of clean electricity annually. This will help major local industrial users in Australia achieve their decarbonization goals, strengthen Queensland’s low-carbon energy infrastructure, and accelerate the regional green energy transition.
BC technology boasts over 40 years of continuous innovation and deep technological roots. Following TCL’s completion of the SunPower integration in March 2025 and the formation of TCL SunPower, the group officially established a dual-brand module operation featuring TCL Solar and SunPower. As an industry pioneer in BC technology, SunPower has dedicated itself to R&D in high-efficiency BC tech since 1985, creating reliable and high-conversion PV products backed by vast core patents and technical expertise. Combined with TCL’s smart manufacturing capabilities, TCL Solar continues to drive the iterative upgrade of BC technology to meet the construction demands of utility-scale power plants.
Parent company TCL Zhonghuan, a top-tier global PV leader, possesses a fully vertically integrated supply chain spanning silicon ingots, wafers, and modules. In 2024, its wafer production capacity ranked first globally, accounting for an 18.9% global market share, with over 4,600 specialized PV patents. Through strategic acquisitions of SunPower in 2025 and DAS Solar in 2026, TCL Zhonghuan has further solidified its leading position in the high-efficiency, premium BC PV sector.
