TCL SOLAR Maximizes Solar Yield with Advanced BC Technology at Intersolar South America 2026
At Booth W4.70, TCL SOLAR is presenting its latest C2 BC modules, alongside real-world performance results and a portfolio of PV solutions designed to address the diverse climatic and energy needs of Latin America.
The exhibition marks an important step in TCL SOLAR’s continued expansion across the region, from hot and humid coastal environments to arid deserts, high-altitude mountains and C&I rooftops, TCL SOLAR’s technology is engineered to deliver reliable performance across diverse climates and applications—bringing the vision of “one high-performance module, more application possibilities” to life.
Advancing Solar Performance with BC Technology
A key highlight of TCL SOLAR’s presence at the exhibition is its new BC (Back Contact) product line, which is designed to deliver higher energy yield while maintaining strong performance under challenging real-world conditions.
Compared with conventional TOPCon modules with the same footprint, TCL SOLAR’s BC modules can deliver an additional 30–40 watts of power. This higher power density can reduce the rooftop area required to achieve the same installed capacity by more than 6%, providing a meaningful advantage for space-constrained applications.
For rural households, farmhouses and agricultural outbuildings, where available rooftop space can be limited, higher power output within the same footprint can enable greater solar capacity without requiring additional roof area. This can help users increase self-consumption and create greater opportunities for grid export.
Stable Performance Under High Temperatures
High solar irradiation is one of Latin America’s key advantages for solar generation, but elevated temperatures can also affect module output. This is particularly relevant for residential and agricultural rooftops, which can experience significant heat accumulation during the summer months.
TCL SOLAR’s BC modules feature a temperature coefficient of -0.26%/°C, compared with approximately -0.28%/°C for conventional modules.
The improved temperature coefficient helps reduce power losses as module temperatures rise, enabling BC modules to maintain more stable output in hot conditions. For households and agricultural users, this can translate into more consistent solar generation during periods when electricity demand is high.
By combining higher power density with improved temperature performance, TCL SOLAR’s BC technology is designed to maximize the value of every available square meter while supporting stable energy production in demanding climates.
Designed for Latin America’s Diverse Energy Landscape
Beyond its BC portfolio, TCL SOLAR is also showcasing its TOPCon module series, providing customers and partners with a broader range of high-performance solutions for different applications and market requirements.
The company’s PV modules are engineered with features including anti-PID performance and salt mist resistance, supporting long-term reliability across a variety of environmental conditions. TCL SOLAR offers a 15-year product warranty and a 30-year linear power warranty, reflecting its focus on long-term product performance and customer value.
These capabilities are particularly relevant to Latin America, where solar installations span a wide range of environments—from urban rooftops and rural residences to agricultural facilities and commercial projects.
Leveraging TCL’s Global Capabilities for the Energy Transition
As a strategic extension of TCL, a global leader in intelligent technology, TCL SOLAR leverages its parent company’s R&D capabilities, global supply chain and manufacturing expertise to accelerate innovation in the renewable energy sector.
“Latin America represents a highly dynamic and promising market for solar energy,” said Donny, Sales Director at Latin America. “We are committed to delivering high-efficiency, reliable PV solutions to Latin America. With our BC and TOPCon portfolios, we look forward to partnering locally to accelerate solar adoption across diverse applications.”
