TCL SunPower Global has launched its C2 solar panel range in Europe, with initial deliveries starting this week in the United Kingdom. The series features back-contact technology designed for residential and commercial applications.
Why it matters
This release follows the company’s July 2026 acquisition of DAS Solar’s manufacturing operations, signaling a rapid scale-up of back-contact production to increase panel efficiency and durability. The rollout marks a competitive shift toward high-performance module architectures in the European market.
The commercial C2 L and C2 L UPP panels achieve 670 W and 24.8% efficiency with up to 85% bifaciality. The system utilizes a full-screen gapless back-contact design, which eliminates front metal busbars to improve performance, alongside a low temperature coefficient of -0.26%/°C.
The players
TCL SunPower Global
A developer of photovoltaic modules and solar energy technology that focuses on high-efficiency back-contact cell manufacturing.
DAS Solar
A manufacturer of high-efficiency solar cells and modules whose production operations were acquired by TCL SunPower in July 2026.
The details
The C2 series uses a gapless back-contact architecture, where all electrical connections are moved to the rear of the cell. By removing the front-side grid lines—the metallic conductors that typically shade a portion of the cell—the design increases the active surface area exposed to sunlight. Production of these modules was significantly expanded after TCL SunPower Global acquired the back-contact manufacturing assets of DAS Solar in July 2026.
Timeline
June 2026: TCL Solar announced the C2 back-contact platform.
July 2026: TCL SunPower completed the acquisition of DAS Solar.
October 4, 2026: The C2 panel range launched in Europe.
Week of October 4, 2026: First deliveries begin in the United Kingdom.
The Tech Race
This release follows the industry-wide transition toward back-contact solar cell architectures to overcome the efficiency limits of standard front-contact layouts. The product range directly competes with existing high-performance module lines by emphasizing long-term output retention of 88.85% after 30 years.
The C2 range is now available to residential and commercial customers through authorized distributors in Europe. Users can expect a 30-year power warranty, with the panels designed to maintain 88.85% of their initial output over three decades.
The takeaway
The C2 series represents a significant push for TCL SunPower into the premium segment of the European market through improved thermal performance and cell design. Interested parties should monitor subsequent announcements for specific pricing structures and availability in additional European countries.
What happens next
TCL Solar is scheduled to implement a broader rollout of the C2 solar panel range across European markets in the weeks following October 4, 2026.
