About product

AC-440MH is a model that uses a number of technologies to bring durability and performance to the next level. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells. 

To further boost the performance, Axitec employs half-cut cell technology. Each of the panel’s 144 cells is only half the size of a traditional solar cell. This grants AC-440MH lower resistive losses and better shade tolerance. The efficiency of this model reaches 20.24% — well above the market’s average. Axitec provides 15 years of product warranty and guarantees that after 25 years, performance will be at 85% or more. 

  • 440 W power output
  • 144 half-cut PERC cells
  • 20.24% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 15-year product and 25-year performance warranties

High productivity thanks to the most recent developments

This Axitec panel produces 440 W of power at 20.24 percent efficiency. High levels of energy output are reached by utilizing the most recent innovations in the solar sector. A more efficient panel produces more per square foot and pays for itself sooner.

Heat-resistant performance

The heat is less of a threat with this module: with one of the lowest temperature coefficients in the industry, AC-440MH loses just 0.35% of efficiency for every 1.8°F above 77°F.

High quality standards

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.

Low degradation for increased longevity

In the first year of service, these panels will lose no more than 3% of their power output. The average yearly power drop from the second to the 25th year will be no more than 0.50%. After 25 years, the modules will retain more than 85% of their initial output.

A panel that can handle hail, wind and snow

This module is weatherproof due to the 1.38" frame manufactured from anodized aluminum and a layer of safety tempered glass. The modules' front and rear sides can withstand loads of 2400 and 2400 Pa, respectively.

So far, I have had no problems with my panels after having them installed.

Our Axitec 440w solar panels are functioning without a hitch, and we're able to track their daily output with the help of Enphase microinverters

The third picture in this product page contains a view of the panel's backside. For your convenience, this page also contains a 3D model of this panel.
All my stuff right now is only 12volt. Can u send 12volt (20voc) versions?

This model doesn't have a 12 V version. However, it doesn't necessarily need to be 12 V in order to be compatible with the rest of equipment in your system. We can give more information if your provide further details
