Tongwei Solar Panel TNC 505WP | Bifacial double glass module with black frame and seamless background

TONGWEI TWMNH-54HD 505W: avant-garde aesthetics and active bifacial generation for urban integration

In contemporary self-consumption projects noon only are hidden in the roofs; Now they are part of the visible structure of buildings. The monocrystalline module 505WP Tongwei TNC it has been specifically designed to respond to this aesthetic and functional demand. Combining an elegant dark perimeter contour with a transparent rear encapsulation, this device becomes the perfect technical solution to dress open architectural spaces that require sifted lighting and high watt density per square meter.

TNC cells of type N and high light transmittance

The technological base of this panel lies in the cells of media N Type Type Type Tongwei TNC Technology. This chemical compound completely eliminates the effects of light-induced degradation (LID), ensuring that silicon maintains impeccable operative stability over the decades. By not having an opaque white background, the sunlight is filtered between the connections of the cells, providing the panel of a high Luminous Transmission ideal for pergolas or skylights. To efficiently inject all the energy generated by this solar field to the home network, it is advisable to derive the current towards inverters solar with multiple MPPT followers, optimizing the performance of each orientation.

The key feature of the 505W model is your native Bifacial Capacity with a power coefficient of 80%. Being protected by a configuration of double semi-tempered glass of 2.0 mm on both sides, The panel absorbs direct radiation by the front and captures the luminous reflection of the environment (Albedo) on the back. This duality allows to increase performance in a real way between a 5% and 15% additional, depending on the lower surface. If you plan to place these units in urban areas with risk of intermittent partial shadows (such as clouds, trees or adjoining buildings), it is recommended to complement the circuit implementing individualized regulation and microinversion systems, Getting that each panel works autonomously.

Mechanical resistance of double glass and sustainability

Despite incorporating a robust structure of double glass of 2.0 mm, the panel maintains a balanced weight of 26.5 kg and a compact format, facilitating installation maneuvers at height. Its robust alloy frame 30 mm black anodized aluminumIt gives you a high mechanical strength in front of windows and snow overloads, guaranteeing a sealing sealing seal with certification Ip68. To fix these elegant dark modules without breaking the visual aesthetics of the assembly, it is ideal to make the assembly on different types of structures for solar available in Tienda Solar, Achieving a clean and minimalist finish.

Frequently Asked Questions (FAQ)

1. What real advantages does the double glass combination offer with a transparent background? This design replaces the opaque rear plastic material by a semi-tempered glass of 2.0 mm high transmittance. This not only gives the panel a stiffness and exceptional fire resistance, but allows the passage of natural light between solar cells. It is ideal for vehicle marquees, balconies or residential terraces, as it generates clean energy without completely dark space.
2. How does the energy gain of Tongwei bifacial technology work? Thanks to its high 80% bifiality coefficient, the back face of the module actively takes advantage of solar radiation reflected by the soil or rear walls. Depending on the color and type of surface (as clear concrete or white gravel), the nominal 505W panel can provide a extra Energy Performance Clean, optimizing the return on investment without the need to add more plates to the installation.
3. What is the difference to TNC technology of type in front of the conventional? The monocrystalline cells with tNC technology (Tongwei N-Type Cell) they use a high purity doping silicon that lacks typical boron-oxygen failures of classic. This translates into a module with a upper efficiency (22.7%), an excellent thermal behavior before high summer temperatures and minimal annual degradation that guarantees a constant supply of long-term energy.
4. What kind of connection terminals does this 505W module include? The panel comes equipped from the factory with photovoltaic cable hoses of 4.0 mm2 and rapid industry standard rapid connectors (compatible with MC4 systems). This ensures perfect, hermetic and low electrical resistance coupling in serial connections, minimizing energy losses in the string and accelerating the mounting times on the cover.
