Monocrystalline Bifacial Solar Panel Tongwei TWMNF-66HD730 TNC2.0 730W (Silver Frame / MC4)

TONGWEI TWMNF-66HD730: Industrial power N-Type TNC2.0, double Bifacial Glass and Efficient Connectivity to 1500V

Profitability in commercial, industrial and scale public photovoltaic projects depends directly on the power density and capacity of modules to operate without losses under demanding environmental conditions. The solar panel Tongwei TWMNF-66HD730 responds to this challenge through its revolutionary cell technology Tnc2.0 of type N in Media Cell format (Half-cell). By optimizing electrical conduction lines and carriers recombination, general solar absorption is maximized and system balance costs (BOS) are reduced, accelerating the return on investment.

Cells N-Type TNC2.0 with advanced thermal coefficient and bifacial performance

The great innovation of the series Twmnf-66hd resides in its 132 monocrystalline cells that operate with a efficiency of initial module of 23.5%. Thanks to its advanced architecture, it has an exceptional bifiality of 80% with variation of more or less 5%, which allows it to capture the radiation reflected by the soil or albedo. On high reflectance surfaces, a subsequent contribution of 10% to 15% drives total equivalent power up to a range of 766W to 839W, raising the effective efficiency of the assembly above conventional standards.

With a coefficient of optimized power temperature -0.28% / ° C, the panel maintains a constant and raised energy flow even in very warm climates or in the central hours of the day, far exceeding traditional silicon technologies. If you plan to channel the enormous power of these modules in demanding industrial facilities, you can integrate this solar field with our advanced range of solar kits high capacity or connect it directly to inverters of centralized network.

Dual-Glass structure, IP68 protection and maximum linear durability

The construction of this module is based on a system of double semi-tempered glass (2.0 mm on the front face and 2.0 mm on the back), replacing the conventional rear plastic sheet by a chemically sealed crystal that completely blocks moisture and corrosive chemical agents. This design Dual-glass it confers an extraordinary mechanical resistance to dynamic loads and certified immunity against degradation by induced potential (PID). It comes equipped with Section 4.0 mm² cables and certified connectors for chains 1500V DC, directly decreasing the necessary copper sections in the installation.

Certificate to resist 5400 PA Front Static Charge (Snow) and 2400 PA rear loading (wind), the module is prepared to operate in the toughest climate environments.

Frequently Asked Questions section (FAQ)

1. What advantages does N-TNC2.0 N-Type cell technology contribute to large-scale plants? The TNC2.0 architecture drastically improves conversion efficiency and electron conduction in silicon type N. When eliminating the boron of the doping process, light-induced degradation (LID) is completely canceled, which translates into a greater generation of kWh per watt installed throughout the project's useful life.
2. How does Bifacial Gain of 80% work in this Tongwei model? The module has a bifiality rate of 80% with a variation of more or less 5%, which means that the back face is highly efficient capturing the reflected light. If installed on surfaces with good albedo (as clear gravel, white industrial covers or sand), the back face can generate an extra power that raises the 730W panel performance to equivalent values of 766W or 839W.
3. Why is the temperature coefficient of -0.28% / ° C in summer critical? As the solar plates heat up at the central hours of the day, its maximum power tends to fall. By having a thermal coefficient of just -0.28% / ° C (significantly lower than the market average), the panel experiences much lower performance falls before extreme heat, guaranteeing superior production in high summer irradiance areas.
4. What benefits does the double glass structure offer compared to with Backsheet? The use of two semi-tempered glass layers of 2.0mm provides an airtight and inert seal for silicon cells. By not having plastic components prone to wear, it eliminates water permeability and corrosion risks by ammonia or saline fog, in addition to completely annulled, induced potential degradation failures (PID).
5. What levels of linear degradation guarantees the manufacturer for the service year 30? Thanks to the high stability of Tongwei type silicon, the degradation of the first year is restricted to a maximum of 1%. As of the second year and until the year 30, the linear annual attenuation is only 0.4%, guaranteeing a contract that the solar panel will operate at least 87.40% of its original performance when completing the three decades.
