TCL Solar highlighted high-efficiency TOPCon modules, with the T5 Pro series reaching up to 670 W and 24.8% efficiency
The company positioned its BC module for space-constrained and high-BOS projects, claiming ~20 W higher output than comparable TOPCon modules
Lightweight modules of ~5.4 kg/m² target rooftop and retrofit applications, aligning with South Korea’s growing focus on distributed solar installations
South Korea is emerging as a steady-growth solar market. The country is targeting 55.7 GW of cumulative installed capacity by 2030, with annual additions expected to exceed 5 GW. Growth is increasingly coming from distributed and floating PV (FPV) systems, where space constraints and system design flexibility play a key role.
TCL Solar, part of TCL Zhonghuan, showcased its latest module portfolio at the Korea Green Energy Expo, highlighting TOPCon and back-contact (BC) technologies for the South Korean solar market.
The company showcased its T5 pro multi-cut TOPCon module, featuring up to 24.8% efficiency and a rated power output of 670 W. It is based on n-type TOPCon bifacial technology combined with a shingled cell structure. Using a glass-glass design, the module offers up to 85% bifaciality.
TCL Solar also presented its BC module, aimed at installations with high BOS costs, limited land availability, or shading constraints. According to TCL Solar, the BC module delivers around 20 W higher output than similar TOPCon products. It also shows improved hotspot resistance and a lower annual degradation rate of about 0.35%.
The company also introduced lightweight modules for rooftop applications. With a weight of around 5.4 kg/m², these modules reduce structural load. This makes them suitable for aging rooftops and retrofit projects, which are becoming more relevant in South Korea’s distributed solar segment.
Alongside its module portfolio, TCL Solar highlighted its upstream integration through TCL Zhonghuan, including large-scale wafer manufacturing capabilities. The company is working with local partners to support project deployment in Korea and expand its regional presence.
