TCL Solar Back Contact photovoltaic panel series utilize advanced cell architecture in which all electrical contacts have been moved to the rear side of the module. This innovative solution completely eliminates shading of the active surface by front busbars, which directly translates into higher solar energy conversion efficiency. Thanks to the use of N-type cells in BC architecture, the panels are characterized by exceptionally low degradation over time and excellent performance in low-light conditions. The unique design based on shingled cell interconnection makes the modules significantly more resistant to micro-cracks and better at handling partial shading. The aesthetics of the series, free of visible metal paths, make it an ideal choice for demanding home users who care about an elegant and modern roof appearance. These panels are dedicated to investors seeking maximum energy yield from a limited area and long-term component reliability. The use of proprietary G12 class silicon wafers provides a technological advantage over competing products, offering one of the highest power densities currently available on the Polish market. This is a premium-class product that effectively solves the problem of energy losses resulting from high ambient temperatures.

Common questions

7 answered
How does Back Contact technology in TCL Solar panels differ from classic panels with visible busbars?
In TCL Solar Back Contact panels, all electrical contacts are moved to the rear side of the module, leaving the front surface free of metal busbars. This eliminates cell shading caused by conductive pathways, resulting in higher solar energy conversion efficiency. An added benefit is a uniform, black appearance without any visible metal elements.
What is the maximum power output of the TCL Solar Back Contact series, and how much energy can be generated from limited roof space?
Panels reach up to 470 Wp thanks to proprietary G12-class silicon wafers combined with shingled cell interconnection, delivering one of the highest power densities currently available on the market. For investors with limited roof area, this means fewer panels are needed to achieve a high total system power output.
Are N-type cells in the BC architecture more resistant to degradation than traditional P-type cells?
Yes, the N-type cells used in the BC architecture show significantly lower light-induced degradation (LID) compared to P-type cells. This results in a slower power output decline over the years and better performance under low-light conditions, such as early morning, evening, or overcast weather.
What warranty comes with TCL Solar Back Contact panels and what does it cover?
The manufacturer provides a 25-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means the panel is guaranteed to retain a specified percentage of its initial power for three decades, making it one of the longest warranty periods currently offered in the PV market.
Does the shingled cell interconnection technology in TCL Solar panels reduce the risk of microcracks?
Yes, the shingled design overlaps cell strips instead of joining them with rigid soldered ribbons, reducing mechanical stress and increasing the module's resistance to microcracks. This structure also improves performance under partial shading, since shading one section has a smaller impact on the output of the entire cell string.
Are TCL Solar Back Contact panels bifacial, and can they generate power from reflected light on the rear side?
No, the TCL Solar Back Contact series consists of monofacial panels optimized for maximum power density and front-side aesthetics rather than rear-side energy capture. Investors interested in bifacial gains can choose a separate product line, while this series focuses on maximizing front-side conversion efficiency.
As a Tier 1 manufacturer from China, are TCL Solar Back Contact panels a safe choice for a residential installation?
TCL Zhonghuan is classified as a Tier 1 manufacturer, reflecting strong financial stability and extensive experience in large-scale silicon cell production. Combined with long warranty periods (25 years on the product, 30 years on power output), this makes the Back Contact series a solid and safe choice for residential installations focused on long-term reliability.
