With electricity costs rising sharply and grid reliability facing persistent challenges, Pakistan’s residential, commercial, and industrial consumers are increasingly turning toward high-efficiency solar solutions. In response to this growing demand, Tongwei Solar is set to showcase its latest innovations at the upcoming Pakistan International Solar Expo, scheduled from April 17–19, 2026, at the Lahore Expo Center (Booth A-1-6).
The company will present its full TNC solar panel series, highlighting advanced technologies designed to improve energy yield, durability, and long-term investment value for Pakistan’s rapidly expanding solar market.
TNC 3.0: Flagship Innovation Driving Next-Generation Efficiency
At the center of Tongwei’s showcase is the *TNC 3.0 module, the flagship product in its advanced photovoltaic lineup. The module incorporates a *quarter-cut cell architecture combined with 360° shielding technology, enabling enhanced light capture and reduced electrical loss.
The TNC 3.0 achieves an impressive efficiency of up to 24.8% and delivers peak power output of up to 770W, positioning it among the most powerful utility-scale modules in its category.
This innovation reflects Tongwei’s continued focus on pushing performance boundaries while maintaining system reliability under diverse environmental conditions.
Comprehensive TNC Portfolio for Diverse Market Needs
Alongside the flagship model, Tongwei will also display its broader range of large-format TNC modules, including:
- G12-66 (2384 × 1303 × 33 mm)
- G12R-66 (2382 × 1134 × 30 mm)
These modules feature advanced *multi-busbar technology (24BB and 20BB), improved current collection efficiency, and strong mechanical durability. Their *bifacial design enhances total energy generation, making them suitable for utility-scale projects, commercial rooftops, and large industrial installations across Pakistan.
The modular flexibility of the TNC series allows developers to select configurations best suited to site-specific requirements, ensuring optimized system design and return on investment.
Engineered for Pakistan’s Extreme Heat Conditions
As Pakistan continues to experience prolonged high-temperature seasons, solar performance under heat stress has become a critical factor for system reliability.
Tongwei’s TNC modules are engineered with a low temperature coefficient of -0.26%/°C, enabling stable performance even when ambient temperatures exceed 40°C. This ensures that energy output remains consistent during peak summer demand periods, when electricity shortages are most severe.
By minimizing heat-related efficiency losses, the TNC series helps users maintain predictable energy generation and improved system resilience under harsh climatic conditions.
Maximizing Output Through Bifacial Energy Capture
A key highlight of the TNC series is its high bifacial ratio of 90±5%, allowing the modules to generate electricity not only from direct sunlight but also from reflected light on surrounding surfaces such as rooftops, sand, and concrete.
This “rear-side generation” significantly enhances total energy yield without requiring additional installation space or cost, making it especially valuable in high-irradiance regions like Pakistan.
The result is a more efficient use of available solar resources and improved overall system performance throughout the year.
Long-Term Reliability and Manufacturing Excellence
Tongwei Solar emphasizes vertically integrated manufacturing, spanning high-purity polysilicon production to cell and module assembly. This end-to-end control ensures consistent quality standards, improved supply chain reliability, and long-term product durability.
The TNC series is designed for longevity, with *annual linear degradation as low as 0.35%, enabling stable output over an estimated *30-year operational lifespan. This long-term performance profile supports investors and developers seeking predictable returns and reduced lifecycle costs.
Global Strength and Local Relevance
As a Fortune Global 500 manufacturer with over four decades of experience, Tongwei Solar combines global scale with advanced research and development capabilities. The company continues to strengthen its international footprint while addressing the specific energy challenges of emerging markets such as Pakistan.
Through dependable production capacity, timely delivery, and technical support, Tongwei positions itself as a long-term partner for Pakistan’s clean energy transition.
