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.

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


How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
Do you offer discounts?
We do offer discounts for orders of over 50 units. Please contact us for details.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
