The TCL Zhonghuan G11RA-72P series introduces a new level of quality to the large-scale photovoltaics sector, basing its design on breakthrough G11 format silicon wafers. The use of such a large cell surface area allows for achieving unprecedented power density, which directly addresses the problem of high installation costs by reducing the number of required mountings and cabling. A key differentiator of the series is the advanced N-type TOPCon cell technology, which offers outstanding resistance to the LID degradation phenomenon and better efficiency in the diffuse light spectrum. These modules were designed for the most demanding industrial investments and solar farms, where the priority is achieving the lowest cost of energy (LCOE) throughout the entire power plant lifecycle. Compared to standard solutions, the G11RA-72P series is characterized by a significantly better temperature coefficient, which minimizes production drops during summer heat. The solid frame construction and high-transmittance tempered glass ensure maximum mechanical resistance to extreme weather events. It is a smart choice for professionals seeking innovation that combines high module performance with the optimization of profitability for large-scale PV projects.

About the G11RA-72P series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

How does Back Contact technology in the TCL Zhonghuan G11RA-72P differ from standard N-TOPCon panels?
In Back Contact modules, all electrical contacts are moved to the rear side of the cell, so the front surface is not shaded by busbars or metallization grids. This increases the active cell area and delivers higher efficiency from the same G11 wafer size compared to standard N-TOPCon modules with visible front-side metallization.
What is the maximum output power of the G11RA-72P series, and how many panels are needed for a 10 kWp system?
The G11RA-72P panels reach a maximum power of 665 Wp. Building a roughly 10 kWp system requires about 15 modules, far fewer than with older 400-450 Wp panels, which meaningfully reduces mounting structure and cabling costs.
What warranty does TCL Zhonghuan offer on the G11RA-72P series?
The manufacturer provides a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means that even after three decades of operation, the panel should retain a high percentage of its original output, which matters for calculating the ROI of an industrial-scale investment.
Are the G11RA-72P panels bifacial modules?
No, the G11RA-72P series consists of mono-facial modules, not bifacial. The design focuses on maximizing front-side power output through Back Contact technology, so it does not rely on additional rear-side light gain as bifacial modules do.
Is it worth choosing G11-format wafers over smaller ones for large-scale solar farms?
Yes, for solar farms and industrial-scale projects, the larger G11 wafer format delivers higher power per module, meaning fewer panels, mounting brackets, and cable connections are needed for the same system capacity. This shortens installation time and lowers the overall LCOE across the plant's lifetime.
Is TCL Zhonghuan a Tier 1 manufacturer, and where is the G11RA-72P produced?
Yes, TCL Zhonghuan is a Tier 1 manufacturer, reflecting its financial stability and large-scale production capacity. Its factories are located in China, and the company ranks among the world's largest silicon wafer producers, giving it full quality control over raw materials starting from G11 cell production.
