Among the newest offerings of Axitec, AC-440TGBL-108BB is part of the AXIblackbiperfect GL series. These panels use state-of-the-art technology to achieve high efficiency and dependability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.
To further boost the performance, Axitec employs half-cut cell technology. Each of the panel’s 108 cells is only half the size of a traditional solar cell. This grants AC-440TGBL-108BB lower resistive losses and better shade tolerance. The efficiency of this model reaches 22.02% — well above the market’s average. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Axitec provides 30 years of product warranty and guarantees that after 30 years, performance will be at 87.4% or more.
This Axitec panel provides 440 W power at 22.02% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including PERC technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.
At high working temperatures, a low temperature coefficient equals increased energy generation. Every 1.8°F over 77°F results in a model's efficiency loss of just -0.31 percent.
Axitec strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.
These panels will lose no more than 1% of their power output in the first year of service. From the 2nd year to the 30th year, the average annual power decline will be no more than 0.40%. The module retains over 87.4% of its original output after 30 years. Guaranteed by Axitec.
The 1.18" frame built of Black anodised aluminium and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 5400 Pa load, whereas the back side can withstand a 2400 Pa load.
The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Axitec engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.

AXITEC Energy stands as a proven European solar manufacturer, founded in 2001 with global headquarters in Böblingen, Germany. This smaller German solar panel brand produces highly efficient and powerful panels with pricing that falls within the mid-range of the industry, leaning slightly towards the cheaper side of the market. With approximately 7 gigawatts of the company's panels installed worldwide and production capacity of 2 GW annually, AXITEC has established itself as a reliable choice for both residential and commercial solar installations.
AXITEC maintains an engineering and design team based in Germany, with production taking place across Asia and Europe. The company has maintained an active presence in the U.S. since 2013, with their subsidiary Axitec Solar USA operating from New Jersey with warehouses in California.
⚡ Performance & Efficiency
AXITEC panels achieve above-average efficiency rates ranging from 22% to 23%, placing them among the higher-end manufacturers. Their panels shine with up to 22% efficiency, standing tall among industry leaders. Even under summer heat, AXITEC panels deliver steady performance thanks to their competitive temperature coefficient ranging from -0.44 to -0.26%/°C.
🛡️ Warranty & Reliability
AXITEC offers an excellent warranty extending to 30 years for both product and performance, surpassing the industry standard. These German-engineered panels are known for their low degradation rate, losing only about 0.4% of their power output per year. The 30-year linear performance warranty stipulates a minimum 87.4% of nameplate capacity at the end of year 30.
🏗️ Product Range & Applications
AXITEC offers a comprehensive product line, including options for residential and commercial applications, as well as bifacial, weather-resistant, and all-black modules. One standout feature is their bifacial design - unlike traditional panels that only capture sunlight from the front, bifacial panels harness energy from both sides, delivering up to 25% more output in diffused light conditions.
💰 Cost-Effectiveness
Solar energy systems using AXITEC solar panels generally cost between $2.00-$2.60 per watt before incentives, placing them well below the average solar panel cost of roughly $3.00 per watt in the United States. Homeowners can expect costs between $2.17 to $2.83 per watt, translating to $13,020 to $16,980 for a 6 kW system, which could drop to $9,114 to $11,886 with tax credits.
"From what I understand and read, AXITEC AXI world premium seems to be pretty efficient at 20.31%, German engineering and as per Solar Lab recommendation better than Longi Panels. So far pairing it with my Fronius Primo 4.0, it is working 101.5%@4060W compared to my Fronius Symo 5.0 at 100.8% @5040W. I am quite pleased with it."
