About product

The Axitec AXI(bi)premium XXL HC MW Series AC-550MBT/144V module uses a number of technologies to bring durability and performance to the next level.

The solar cells of AC-550MBT/144V are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life and enhanced efficiency in low-light conditions. Given its size and weight, AC-550MBT/144V efficiency of 21.29% is quite impressive. 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. Axitec paid as much attention to durability as they did to performance. AC-550MBT/144V is guaranteed to retain at least 85% of output after 25 years. Product warranty for this panel lasts 15 years.

  • 550 W power output
  • 144 half-cut cells
  • 21.29% efficiency
  • 1000V/1500V DC maximum system voltage
  • Staubli EVO2 connectors
  • 15-year product and 25-year performance warranties

Increased power and efficiency

PERC technology improves on an already high efficiency of 21.29 percent. The manufacturer created an efficient and highly durable model by adding a robust PID resistance and unique glass lamination on top. AC-550MBT/144V produces 550 W of power under standard test conditions.

Heat-resistant performance

The heat is less of a threat with this module: with one of the lowest temperature coefficients in the industry, AC-550MBT/144V loses just -0.35% of efficiency for every 1.8°F above 77°F.

Quality and reliability

AC-550MBT/144V receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. Axitec is dedicated to quality, safety and reliability to ensure you get the very best.

Low degradation for a longer lifespan

These panels will lose no more than 3% of their power output in the first year of service. From the 2nd year to the 25th year, the average annual power decline will be no more than 0.50%. The module retains over 85% of its original output after 25 years. Guaranteed by Axitec.

Certified for the worst environmental conditions

AC-550MBT/144V is PID, salt, acid, and ammonia resistant. It can also bear mechanical loads of up to 2400 Pa. This durability is mostly owing to the 1.38" thick aluminum alloy frame and a layer of protective glass.

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
