Amid the full-scale emergence of N-type technology, competition in photovoltaic modules has evolved from a singular focus on efficiency to a comprehensive contest of value across all scenarios and throughout the entire lifecycle. How can every ray of sunlight be harnessed to its utmost potential? Tongwei's TNC 3.0 module answers this call of the times with its "robust performance" – the TNC 3.0 G12R-66 version achieves a maximum power of 670W and a conversion efficiency of 24.8%, while the TNC 3.0 G12-66 version reaches up to 770W with the same 24.8% efficiency, leading the industry in performance for 210mm cell modules. Integrating multidimensional strengths such as peak power output, high-temperature resistance, shading optimization, and high bifaciality, it aims to "crown the light," building an unshakable moat of value for power plant owners worldwide.

01 The Balance Between Current and Heat Loss: A "Cooler" High-Energy Core

In the operating principle of PV modules, electric current is both the carrier of energy and a source of thermal loss. TNC 3.0 employs a quarter-cell design, splitting each cell into four parts, which reduces the operating current per cell by three-fourths. This sharp drop in current delivers an immediate "cooling" effect: power loss due to resistance within the module is significantly reduced, allowing more of the electricity converted from light to be safely delivered outside the module. Simultaneously, the low-current characteristic, combined with a higher cell open-circuit voltage, gives the module a lower power temperature coefficient. Even under harsh conditions like midday high temperatures and intense irradiation, TNC 3.0 remains "cool," avoiding power degradation caused by excessive temperature rise and ensuring sustained, stable high-energy output.

Moreover, the low-current design builds an ultimate safety line of defense for the module. Even if hotspot effects occasionally occur, the hotspot temperature is markedly lower than in conventional modules, greatly reducing the risk of module failure.

02 Reengineering the Current Path: From "Two Lanes" to a "Four-Lane" Smart Highway

Outdoor environments are complex and variable, and even rare occurrences like cloud shadows or tree shading can affect some power plants. Traditional half-cut modules typically adopt a two-section parallel structure, akin to a "two-lane" road – once a blockage (shading) occurs, half the module's production capacity is paralyzed.

TNC 3.0 reengineers the internal current path structure, upgrading the parallel circuits from 2 sections to 4 sections. This upgrade is equivalent to expanding the power transmission channels into independent, non-interfering "four-lane" highways. When part of the module is shaded, current can quickly divert through the remaining three clear "lanes." This high-redundancy circuit design minimizes power generation loss caused by partial cell shading, significantly enhancing the module's anti-shading capability under non-ideal conditions.

03 All-Weather Power Generation Logic: Unfazed by Clouds or Sun, Transcending Dawn and Dusk。

A true levelized cost of electricity (LCOE) champion must possess all-weather operational capabilities. TNC 3.0 excels not only under high-temperature, sunny conditions but also performs with full strength in low-light environments.

Benefiting from the ultra-high automation level, stable quality control, and outstanding passivation quality of the world's first photovoltaic cell lighthouse factory, TNC 3.0 boasts stronger spectral response capabilities and lower leakage current. During low-light periods such as cloudy and rainy days, early dawn, or sunset dusk, it can still sensitively capture photons and maintain efficient power generation. This enables truly all-weather, full-capacity operation from dawn to dusk, and from overcast rain to intense heat, ensuring that every ray of light is utilized to its fullest.

04 A Dual Symphony of Value: One Side Free Gain, the Other Side Compounding Over Time

For power plant owners, what is the most direct promise of value? The answer is not merely "better value retention" but "added value growth." TNC 3.0 inherits the superior genes of Tongwei's POLY TECH technology, elevatingthe bifaciality to an industry-leading 85%.

This means that in high-reflectivity scenarios like snowfields, sandy ground, and concrete surfaces, the module's rear side can capture additional light energy. This extra power generation gain from the rear side is essentially a "free value gift" to customers brought by technological advancement. Every additional kilowatt-hour generated is a pure increase to the customer's revenue, turning "free" sunlight into tangible financial returns.

While providing added value, Tongwei also gives TNC 3.0 an ultimate long-term commitment—a linear degradation rate as low as 0.35% per year. This means that from the first day of grid connection until its decommissioning 30 years later, the cumulative power generation over its entire lifecycle will create a significant "snowball" or compounding effect. Lower degradation translates to greater lifecycle value, which is Tongwei's confidence in quality and a solemn guardianship of every bit of the customer's investment.

From microscopic innovations in cell structure to macroscopic improvements in power plant returns; from significantly reduced LCOE to all-weather stable output. Tongwei TNC 3.0 uses data and real-world performance to define what "Robust Performance" truly means.

This is a product that genuinely "crowns the light"—fully unlocking the value of every sunray and converting it into assured long-term returns for the owner.

Choose Tongwei, choose TNC 3.0, and win in the N-type era.
