The new modules have a bifaciality of 85%, an efficiency of up to 24.8%, an annual degradation of 0.35% and a 30-year performance guarantee.
TCL SunPowera division of Chinese PV manufacturer TCL Zhonghuan, has launched a new range of solar panel panels based on TOPCon cell technology.
The new TCL Solar T5 Pro product line combines TOPCon multi-cut cell technology with a shingle design, which the company says eliminates inactive holes in the cell surface, allowing for greater light capture. An optimized circuit design ensures stable performance under partial shade conditions.
“The module is designed for long-term use and uses flexible connections to reduce the risk of micro-cracks and mechanical stresses over time,” the manufacturer said.
The product is available in two versions: the T5 Pro S model from 450 W to 475 W for rooftop applications, and the T5 Pro L module from 640 W to 670 W for large roof and ground projects.
The smaller module is offered in six power classes, ranging from 450 W to 475 W, with module efficiencies up to 23.8%. The 475 W variant provides an open-circuit voltage of 54.89 V and a short-circuit current of 10.95 A.
Designed for residential roof applications, the modules measure 1,622mm x 1,134mm x 30mm and weigh 24.5kg. They are constructed with 2.0mm heat strengthened glass and framed in black anodized aluminum. The junction box has an IP68 rating and the temperature coefficient is -0.26%/°C. The modules are suitable for a maximum system voltage of 1,500 V DC and operate within a temperature range of -40 C to 85 C.
For C&I and utility applications, the larger series offers output levels from 640 W to 670 W, with efficiencies up to 24.8%. At STC, the 670 W version achieves an open-circuit voltage of 50.58 V and a short-circuit current of 18.42 A.
These modules measure 2,382mm x 1,134mm x 30mm and weigh 32.6kg, reflecting their larger size and higher power density. As with the residential line, they feature 2.0mm heat-resistant glass and IP68-rated junction boxes.
Both product lines have a temperature coefficient of -0.26%/C, a first year degradation rate of 1% and a maximum annual degradation of 0.35%. They come with a 25-year product warranty and a 30-year performance warranty.
According to the manufacturer, both modules have been tested to withstand mechanical loads of up to 5,400 Pa at the front and 2,400 Pa at the back, making them suitable for roofs exposed to heavy snowfall or strong wind loads.
“TCL Solar also emphasizes the bifacial performance of the modules, with a bifacial factor of 85%, allowing additional rear power generation and improving overall system yield,” the company added.
