TCL Solar C2 Back-Contact Panels Now Available in Europe

On October 2, 2026, TCL SunPower Global announced a significant step forward in solar technology with the launch of its TCL Solar C2 back-contact panels across Europe. Following their initial reveal at major industry events such as SNEC in Shanghai and Intersolar Europe in Munich, these innovative solar modules are now ready for order through authorized distributors. The first deliveries are expected to reach the UK this week, paving the way for an extensive rollout across the continent in the coming weeks.

The TCL Solar C2 marks an important evolution in solar panel design, shifting from mere announcements to a commercially viable solution for a range of applications including residential, commercial, and utility-scale solar installations. Steven Zhang, CEO of TCL SunPower Global, emphasized the brand's commitment to innovation, stating, "The C2 range represents the next generation of our back-contact platform and clearly indicates our brand's future direction."

Over the past year, TCL SunPower has significantly scaled up production capabilities, particularly through the acquisition of DAS Solar's back-contact cell and panel manufacturing operations completed in July. This acquisition, alongside over 1,600 patents related to back-contact cells and decades of experience in photovoltaic module manufacturing, has positioned TCL Solar to redefine solar expectations in Europe.

Key Features of the TCL Solar C2

The TCL Solar C2 lineup includes two configurations derived from the same back-contact cell technology. The C2 S Black model targets residential rooftops and small commercial rooftops, boasting a maximum output of 495 watts and an impressive efficiency of 23.8%. Meanwhile, the C2 L and C2 L UPP models are designed for larger commercial projects and utility-scale solar parks, with capabilities reaching up to 670 watts and efficiencies of 24.8%. The bifacial technology in certain versions allows for an energy yield that can reach up to 85%.

These panels feature a distinctive back-contact design that optimizes the active surface area, eliminating the metal busbars found in traditional panels. This innovative construction enhances power density, providing over 5% more usable power per panel compared to similar models with front-contact configurations. Global performance metrics exhibit a temperature coefficient of -0.26% per °C and an annual degradation rate of less than 0.35%, which means that these panels retain approximately 88.85% of their original capacity even after 30 years.

Karin Alberto Burkhardt, TCL SunPower's Director of Photovoltaic Products, explained, "The busbar-free cell design eliminates shadowing from the grid lines typical in standard panels. This design approach not only boosts efficiency but also enhances aesthetics, particularly in the S Black model which provides a uniform black finish."

Warranty and Availability

Backing the quality of the C2 modules, TCL Solar offers a robust long-term warranty, including a product guarantee of up to 25 years and a performance warranty of 30 years, depending on the specific model chosen. The C2 panels are now available for order through authorized TCL Solar distributors throughout Europe. Installers and professional buyers can locate their nearest distributor using the tool accessible at tclsolar.com/distributors.
