  • 1. Unmatched High Efficiency
    MateSolar's N-type HJT 430W, 435W, 440W, 445W, 450W and 455W All Black Bifacial Double Glass Solar Panel achieves a leading module conversion efficiency of up to 23.3%. This high efficiency, combined with ultra-low light-induced degradation (LID), ensures superior energy harvesting. The panels deliver exceptional performance not only under standard test conditions but also maintain high relative efficiency in weak light, such as during mornings, evenings, or cloudy days, maximizing daily energy yield.

    2. Superior High-Temperature Performance
    Engineered for stable operation, our HJT panel features a low temperature coefficient of -0.26%/°C. This advanced characteristic significantly reduces power loss in high-temperature environments compared to conventional modules. It ensures more consistent and reliable energy production during hot days, protecting your investment's returns and providing greater energy output in warm climates.

    3. Robust SMBB & Half-Cell Design
    The integration of Smart Multi-Busbar (SMBB) technology and a half-cell layout minimizes internal electrical resistance and reduces power losses. This design lowers operating temperature and mitigates hotspot risks, enhancing the overall reliability and durability of the module. The optimized cell layout ensures higher module efficiency and contributes to a greater total power yield over the system's lifetime.

    4. High Bifacial Gain & Durability
    Featuring a symmetrical double-glass structure, this bifacial panel captures reflected sunlight from the rear side, offering up to 90% bifaciality for significant additional energy gain. The robust glass-glass construction and high-grade sealing materials provide excellent protection against moisture, corrosion, and environmental stress. This results in exceptional long-term durability, a slower power degradation rate, and an extended operational life exceeding 30 years.

FAQS

Q :

What is HJT technology, and why is it superior for my solar installation?

A :

HJT (Heterojunction Technology) combines different types of crystalline silicon to create a highly efficient solar cell. MateSolar's HJT panels offer higher conversion efficiency (up to 23.3%), better temperature performance, and lower degradation rates compared to traditional PERC modules, leading to significantly greater energy production and lifetime savings.

Q :

How does the bifacial feature work, and how much extra energy can I expect?

A :

Bifacial panels generate power from both sides. The front side captures direct sunlight, while the rear side captures light reflected from the ground (albedo). Depending on your installation surface (e.g., white gravel, concrete), MateSolar's panels with up to 90% bifaciality can achieve substantial energy gains, often between 10% to 30% more than standard monofacial modules.

Q :

Why is a low temperature coefficient important?

A :

The temperature coefficient indicates how much a panel's power output decreases as its temperature rises. Our low coefficient of -0.26%/°C means MateSolar HJT panels lose less power in hot weather than conventional panels (which can be -0.34%/°C or higher). This ensures more stable and reliable performance during summer or in high-temperature regions.

Q :

Are these panels effective on cloudy days or in low light?

A :

Yes. Thanks to the inherent advantages of HJT cell technology and high-quality N-type silicon, our panels exhibit excellent weak-light response. They maintain a high relative efficiency, ensuring meaningful power generation during early mornings, late afternoons, and overcast conditions, thus maximizing daily energy harvest.

Q :

What are the benefits of the double-glass and all-black design?

A :

The double-glass structure provides superior protection against humidity, corrosion, and physical stress, leading to exceptional durability, a 30-year+ lifespan, and a lower degradation rate. The all-black aesthetic, with black frames and cells, offers a sleek, uniform appearance preferred for residential and commercial rooftops.

Q :

How does the SMBB and half-cell design improve reliability?

A :

The Smart Multi-Busbar (SMBB) design reduces electrical resistance, while the half-cell layout lowers current within each cell string. This combination minimizes energy losses, reduces thermal stress, and significantly decreases the risk and impact of hot spots caused by partial shading, thereby enhancing the module's overall long-term reliability.

Q :

What advantages does 90% bifaciality provide?

A :

It captures additional rear-side energy, while advanced PIB sealing enhances water resistance and extends lifespan.

Q :

What warranties does MateSolar provide with these HJT panels?

A :

MateSolar stands behind the quality of our HJT panels with a robust warranty package. This typically includes a long-term product warranty (e.g., 15-25 years) and a performance warranty guaranteeing that the panels will still produce a high percentage (e.g., over 90%) of their original power output even after 30 years of operation.

Q :

Are HJT panels more susceptible to PID or LID?

A :

On the contrary, MateSolar's HJT panels demonstrate excellent resistance to both Potential Induced Degradation (PID) and Light-Induced Degradation (LID). The use of N-type silicon base and intrinsic amorphous silicon layers makes them inherently less prone to these efficiency losses, ensuring stable power output from the very beginning and throughout their lifecycle.

Q :

What mounting systems are suitable for these bifacial panels?

A :

To maximize the energy gain from the bifacial feature, we recommend mounting systems that allow sunlight to reach the panel's rear side. Elevated racking (with adequate ground clearance), tracker systems, or installations over highly reflective surfaces are ideal. Our technical team can provide specific guidance for your project site.
