I placed an order for axitek panels 3 days ago, today I already received them at the storage nearby. Manger Melani was really nice,
here's to keep you posted: bought axitec panels in the middle of July, received them by the end of the month. a bit longer than expected, but with these prices i am more than happy with how it turned out.
the UI of your website is so much better than what the rest have, it's staggering. as far as panels go, they are good. Delivery was very nicely timed

choosing the right solar panels was really confusing for me. i wasn't sure what to look for and felt overwhelmed. your staff was amazing – they explained everything in simple terms and helped me make an informed choice. the panels were delivered quickly and have been working flawlessly ever since. i'm grateful for their support and will definitely return.

Installed these panels 2.5 years ago, Recently one "shattered" for an undetermined reason. It's on the roof of a 2 story house in a development of elderly people. Not like someone climbed up there with a bat. Not covered under warranty so I'm out of pocket for the replacement.
So far, I have had no problems with my panels after having them installed.
Selected the black on silver panels with 440 watts in each. Very good price
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!
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
Been running them for a month, performance is solid.
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.
Design: superb Performance: great Service: no complaints me fully satisfied.
Budget-friendly panels that power my home with no problems would recommend.
It is great to see solar panels not only from Asia, but from America and Germany as well. Panels arrived, they are in great shape, thanks a bunch!
Delivered on time, thanks guys.
I loved the design! Looks very stylish to me. The performance is great and i expected nothing less from german minds
thanks for your calculator. it helped a lot. the delivery was fine, the panels are fine, they are in the garage right now. we’ll finish the installation in a few days
Happy with the warranty on these panels.
There was an issue that the panels I ordered initially were sold out, so they found a comparable panel and gave me the same price. Great service
Great service, shipping, delivery on time, great price
The installation was quick, and they started generating power right away.
I received my order finally. It was very well packaged and I appreciated the plug and play ease with my RV. The first time I used it, I had my RV in the shade but could still charge my batteries. I couldn’t be happier with it. Thank you!
Really good quality panels. These are German-made modules that produce energy very efficiently. They are very highly rated and have a great warranty. We are very happy we used Axitec Panels.
The purchasing experience was great we got our solar panels way quicker than expected in perfect condition. Customer service is great
Great looking panels that produce as was promised. Their quality appear excellent.
These are German-made panels so I know that they have superior quality. I am already impressed with their efficiency especially considering how affordable they are.
High wattage panels with great performance and at a very reasonable price point.

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%.
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.

About product

AC-580TGB-144TS is a model that uses a number of technologies to bring durability and performance to the next level. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

Another advantage is the half-cut cell technology. AC-580TGB-144TS 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. The efficiency of this model reaches 29.18% — well above the market’s average. 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 provides 30 years of product warranty and guarantees that after 30 years, performance will be at 87.4% or more.

  • 144 half-cut PERC cells
  • 580 W nameplate capacity
  • 29.18% efficiency
  • 1500 V DC maximum system voltage
  • Stäubli MC4 connectors
  • 30 years of product and 30 years of performance warranty

High efficiency of 29.18 percent

Axitec AXIbiperfect GXXL TS panels fully use the firm's innovations, which Axitec has received several distinctions for. With PERC technology, more electricity can be produced per square foot of PV modules. As a result, there will be less clamps and racks required during installation. All of which lowers your overall expenses and accelerates the payback period.

Exceptional performance in hot temperatures

A low temperature coefficient provides more energy output at high working temperatures. AC-580TGB-144TS loses just -0.31 percent efficiency for every 1.8°F over 77°F.

High quality standards

Multiple tests are part of the Axitec tight production requirements, which offer the highest level of quality assurance. Because of the facilities' high degree of automation, the business is able to uphold strict standards and minimize the number of warranty claims to an absolute minimum.

Low degradation for increased longevity

In the first year of service, these panels will lose no more than 1% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.40%. After 30 years, the modules will retain more than 87.4% of their initial output.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm AC-580TGB-144TS. Furthermore, it has a mechanical load resistance of up to 5400 Pa in the front and 2400 Pa in the back. A layer of protective glass and 1.2" thick anodized aluminum alloy frame are the primary reasons for its toughness.
