Tongwei Tongwei Solar Solar Panel TWMNH-48HW455 N-TYPE 455W (Black Frame / MC4)

Tongwei TWMNH-48HW455: Dual-Glass N-Type innovation, Aesthetics Black Frame and topvoltaic performance

Maximize energy production in residential and commercial self-consumption projects requires components capable of combating structural resistance, high efficiency and minimum long-term degradation. The solar panel Tongwei TWMNH-48HW455 responding accurately to these requirements through the use of monocrystalline cells of type N with technology TNC arranged in a media-cell configuration or Half-cell (96 cells). This design significantly decreases internal losses due to ohmic resistance and optimizes the behavior of the module against partial shading or low irradiance conditions, guaranteeing a constant flow of power.

N-type cells with optimized thermal coefficient and stability against degradation

The main advantage of the series Twmnh-48hw lATES IN ITS SILICIC TYPE ARCHITECTURE TYPE WITH PHOSFORE IN PLACE OF BORON, which completely eliminates the effects of light-induced degradation (LID). With a 22.8% module efficiency and a positive power tolerance from 0 to + 3%, each panel ensures the net delivery of the 455W nominal rated measuring conditions (STC).

This is added an outstanding power temperature coefficient of -0.28% / ° C, which allows solar plates to operate with minimal losses during the hottest months of the year or at the hours of maximum direct solar exposure. If you are looking to structure a high-end residential system, this panel combines ideally with inverters network efficient or can be integrated flexibly into advanced projects that use lithium batteries for energy storage.

Dual-Glass Construction High Strength and Performance Warranty 30 Years

In front of the conventional with plastic back sheet, this model stands out for its structure Dual-glass, composed of a semi-tempered 2.0 mm front glass with antireflective coating (AR) and a semi-tempered rear glass of 2.0 mm. This double barrier of glass hermetically seals the cells versus humidity, corrosion by ammonia or saline fog, nullifying the risks associated with induced potential degradation (PID) according to IEC certifications. The set is framed in an anodized black anodized alloy of 30 mm that connects mechanical strength and a clean aesthetics on the roof.

The panel is certified to withstand severe mechanical loads, tolerating 5400 pa on the front face (snow) and 2400 PA on the later (wind). It has 4.0 mm² output cables with a length of 1200 mm and an IP68 connection box with 3 bypass diodes to protect the circuit. Backed by Bloomberg Tier 1 status, the manufacturer offers a guarantee of materials of 15 years and one 30-year linear power guarantee, certifying that the degradation of the first year will be less than or equal to 1% and the following years less than 0.4%, reaching a performance from 87.40% at the end of the three decades.

Frequently Asked Questions section (FAQ)

1. What benefits does dual-glass technology provide against a conventional panel? The double glazing structure replaces the rear plastic sheet by semi-tempered glass of 2.0 mm. This generates a perfect isolation against abrasive outer agents, prevents moisture degradation and completely cancels PID failures (induced potential degradation), extending the actual operational life of the system.
2. Why is N-TNC silicon superior for self-consumption? N-type NNC cells achieve higher efficiencies (22.8% in this model) and eliminate initial degradation by light exposure (LID). This is translated that the installation produces more kWh per square meter from the first day and maintains a very higher generation stability over the years.
3. How does the temperature coefficient of -0.28% / ° C influence in warm climates? The solar decrease its performance as its physical temperature exceeds 25 ° C. With a thermal coefficient of just -0.28% / ° C, this module retains a substantially higher generation capacity in summer versus conventional, optimizing photovoltaic performance at the central hours of the day.
4. What kind of maintenance or precautions does the Black Frame finish require? The black anodized aluminum frame offers excellent weather resistance and an elegant and clean visual finish. At the mechanical maintenance level, the same cleaning standards are applied with water than a conventional panel, guaranteeing the anchors and the structures for solar respect the clamping areas specified by Tongwei.
5. What is the behavior of degradation guaranteed at age 30? Tongwei certifies by contract that loss of performance during the first year will be less than or equal to 1%. As of the second year, linear reduction is limited to a maximum of 0.4% per year, ensuring that the module will maintain, at least 87.40% of its original nominal capacity upon arrival at year 30.
