About product

Among the newest offerings of Axitec, AC-450MH is part of the AxiPremium series. These panels use state-of-the-art technology to achieve high efficiency and dependability. 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. 

Another advantage is the half-cut cell technology. AC-450MH has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. At 20.7% efficiency, AC-450MH offers surprising performance for its weight and size. Axitec provides a 15-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years. 

  • 144 half-cut PERC cells
  • 450 W nameplate capacity
  • 20.7% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 15 years of product and 25 years of performance warranty

More power and efficiency

An already high efficiency of 20.7% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, AC-450MH outputs 450 W of power.

Better performance at high temperatures

An excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel’s efficiency by only 0.35%.

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.

Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by Axitec. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 85% of original performance after the 25 years are over. This 450 W Axitec solar panel also comes with a generous 15-year product warranty.

A panel that can handle hail, wind and snow

The 1.38" frame made from anodized aluminum and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 2400 Pa load, and the back side 2400 Pa.

Everyone is after the all-black panels, but these Axitec modules with a silver frame are aesthetically pleasing and don't ruin our roof line. We believe it improves the appearance of the front of our house!

I'm pleased with how neat they appear, and I really enjoy the skirt my installer added to the bottom of my panels. When compared to other solar installations I've seen in the area, ours is a clear winner.

Would this 450 watt Axitec panel be large enough for a 27 ft travel trailer with 3 way (propane , electric, and battery capability)

It will mostly depend on your energy consumption. This model can produce 2.3 kWh per day assuming 5 peak sun hours.

Hi, Do I need an electrician to hook it up on my electrical system? Does it come with converters and all needed pieces to be hooked up? I'm a shareholder and Fed up with pollution, thinking about it for my personal apartment, can it be done? Jackie

Hello! Whether you need an electrician or not depends on the local laws. Some states require that an installation be performed by a certified professional. No other equipment is provided with the panels. If you need a turnkey solution, please press "Systems" at the very top of this page.


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
