TCL Zhonghuan presented its X1 series wafers, suitable for TOPCon, HJT, and xBC cell technologies at the show
The company also promoted its T5 Pro TOPCon and C2 series BC modules with a rated power output of 470 W and 485 W, respectively
The former is rated for a maximum efficiency of 23.5%, while the latter is rated at 23.8%
TCL Zhonghuan, a well-known China-based company that manufactures PV wafers, modules, and, recently, energy storage systems (ESS), showcased its product portfolio at REI 2026.
From the upstream segment of the PV value chain, the company displayed its X1 wafer series. According to its press release, the wafers are made using optimized crystal-pulling technology and AI-assisted processes in an Industry 4.0 dark factory. They are compatible with the latest cell structures, including TOPCon, HJT, and xBC.
The company also introduced its T5 Pro (TOPCon) and C2 series (BC) PV modules for the country’s utility-scale, commercial & industrial (C&I), and residential applications.
The T5 Pro uses 48 TOPCon cells, each cut into three slices along the length, for a total of 144 cut cells and strings them in a shingled cell design (overlapped cell-to-cell). The product datasheet specifies a rated power output of up to 470 W, an efficiency of up to 23.5%, and dimensions of 1,762 × 1,134 × 30 mm (L × W × D). TCL claims its 1/3rd-cut cell design yields up to 17% higher power generation compared to its half-cut peers under partial shading conditions. It has a rated temperature coefficient of -0.26%/°C. It has 2 mm glass on the front and the rear, and weighs 24.5 kg.
In comparison, the C2 is equipped with 108 half-cut BC cells, overlapped with one another (along the width edges) in a shingled design. The company says this design yields 15 W higher maximum power output and a 0.3 percentage-point efficiency gain. It has slightly larger dimensions of 1,800 × 1,134 × 30 mm and employs a full-screen design with 2 mm front and rear glass. It also exhibits better resilience against partial shading and performs better in low-light conditions, the company added.
Both modules have a 25-year product warranty and a performance warranty for up to 30 years.
The company also displayed its BluArk X1, BluArk X5, and BluArk W10 ESSs.
TaiyangNews has recently published its "Balance of System (BoS) Components 2026" report, featuring inverters, storage and technology trends presented at SNEC and Intersolar Europe 2026.
