About product


Aptos 440W DNA Split Solar Panel shows great usage of modern technologies for maximum performance. This PV module is a great choice for commercial and utility-scale solar systems. Many Aptos DNA-144 440W reviews point out that even at extreme temperatures this panel retains high efficiency.


  • 440W rated power output 
  • 20.21% efficiency
  • Temperature Coefficient Pmmp: -0.36%
  • Degradation rate: -0.54%
  • 25 years product warranty, up to 30 years performance warranty
  • Maximum load capacity: 5400 Pa snow load / 210 mph wind

High shading and extreme temperatures tolerance

The manufacturer claims that the Aptos 440W solar panels have high shading tolerance and perform very well at high temperatures. The power temperature coefficient is at -0.36% which shows that extreme heat won’t be much of a problem.

Modern technologies raise the efficiency to 20%

Engineers have implemented Dual Nano Absorber (DNATM) Technology for higher efficiency of Aptos 440 watt panels, especially at high temperatures. Besides, each module has 9 busbars which improve the flow of current inside a panel and lower power losses.

Reliable and long-longlasting

Solar cells of Aptos 440W panels are protected by a frame of black anodized aluminum and a 3.2 mm layer of tempered glass with anti-reflective coating. The module is made to withstand 5400 Pa snow loads and 210 mph wind load. Failure rate of Aptos Solar panels is less than 0.01%

Industry leading 30 year warranty

Not many solar manufacturers provide a product warranty that lasts longer than 10-15 years, and a 30 year performance warranty is almost unheard of. Nevertheless, Aptos Solar offers their customers a 25 year product warranty with a warranty for production for up to 30 years. After 25 years the power output of the Aptos DNA-144 440W module won’t fall below 85%. Optional extended warranty guarantees you over 82% of initial production after 30 years, according to Aptos 440W spec sheet.

Impressive aesthetics

‘No excessive silver bussing or ribbons’, claims the manufacturer. All-black Aptos 440W module is going to look stylish wherever you install it.

We used those at our farm in Texas. They are pretty good. Usually when it’s hot the production drops, but here – nope, everything was working as it should. For this money it’s a good deal, imo

Panels arrived, thank you. I chose those because of warranties and safety. the performance was good last time i checked. honestly, it just feels great to have quality product and not be afraid that they are going to break down in the next second

Available pickup locations are listed under the price.
are those canadian? i swear i heard about aptos before

No, those are actually American panels, they are designed and engineered in California.
Good day, could you tell what’s the weight of a full pallet and how many modules fit in it?
07/26/2021, 12:22
Good day. One pallet can fit 27 modules and its weight is going to be 1500 lbs.


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
