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.
