TCL Solar has expanded its footprint in Europe by launching the C2 back-contact photovoltaic module range. The product line includes residential panels and a high-capacity M model designed for large-scale utility projects.
Why it matters
This release signifies a major push by TCL Solar to advance back-contact technology in the global market. The company is actively scaling up its manufacturing infrastructure to support the production of these high-efficiency modules on a massive scale.
The C2 M module achieves a maximum power output of 670 W with an efficiency range starting at 23.9%. The hardware features a 1,500 V DC system voltage rating and a maximum annual power degradation of 0.35% over a 30-year linear coverage period.
The players
TCL Solar
This subsidiary of TCL Technology specializes in the research, development, and manufacturing of advanced photovoltaic modules and solar energy solutions.
TCL Zhonghuan
This entity is a major manufacturer of semiconductor and solar silicon wafers that manages the broader manufacturing infrastructure for TCL.
DAS Solar
This company is a specialized manufacturer of high-efficiency photovoltaic products that was recently acquired by TCL Zhonghuan.
The details
The residential version features a 108-cell configuration with a gapless design, while the C2 M model utilizes 132 G12R back-contact cells in an n-type bifacial construction. Both modules are built with 2.0 mm heat-strengthened front and rear glass and are rated to withstand an operating temperature range of -40 C to 70 C.

Deeper Dive
The expansion into back-contact technology represents a strategic move to move beyond the industry-standard N-type tunnel oxide passivated contact (TOPCon) solar cell manufacturing standard. By converting 20 GW of cell capacity and 25 GW of module capacity, the company aims to establish back-contact architecture as the new efficiency benchmark.
These modules offer higher conversion efficiencies that could lead to lower energy costs for large-scale utility projects and residential consumers. The 30-year linear power coverage duration and durable heat-strengthened glass construction suggest improved long-term reliability for solar installations.
The takeaway
TCL Solar is aggressively pivoting its production capabilities toward back-contact technology to capture a larger share of the global solar market. Readers evaluating solar investments should monitor these efficiency benchmarks as they likely signal a shift in standard hardware performance expectations for future installations.
