About product


Bifacial 440W Aptos Solar panel produces up to 30% more energy than standard monofacial modules. They are a great choice for commercial and utility-scale systems. Panels are very resilient in extreme weather and backed up by strong warranties.


  • Bifacial 144-cell solar module
  • 440 W rated power output
  • 20.21% efficiency
  • 25 years product warranty, up to 30 years performance warranty
  • 5400 Pa snow load/ 6200 Pa wind load capacity

30% more efficiency with bifacial module

Aptos Solar module has solar cells on the rear side as well as on the front. That allows them to harvest around 30% more energy than conventional modules. You get maximum efficiency for the space that you use.

Modern technologies raise the efficiency to 20%

Patented Dual Nano Absorber (DNATM) Technology ensures higher efficiency, 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 are protected by a frame of anodized aluminium and a 3.2 mm layer of tempered glass with anti-reflective coating. The module is made to withstand 5400 Pa snow loads and 6200 Pa wind loads. 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 a module won’t fall below 85%. Optional extended warranty guarantees you over 82% of initial production after 30 years.

I run a cafe in San Antonio and I wanted to go for something modern to make my place stand out. This was it. Not only are these panels super efficient, they make the building special, really attractive. ty

We came in contact with a1solarstore about 6 months ago. We explained that we need to build a system for our factory in Louisiana. This was the model they offered us. The product was supplied in time, the staff was very professional. The installation took a long time as it is with projects of this scale. The performance is great! It impressed us with how much energy you can actually get from a relatively average-size area. Thanks for the great recommendation, it was a pleasure doing business with you.

then what’s the point? i mean i could get two panels for the same money probably.

With bifacial panels you use your space more efficiently. It’s a good choice when space is limited: the roof is small, or it’s for a boat or a van.
do they produce twice as much? since it’s two panels in one?

No, the rear side receives much less sunlight. The production of bifacial panels is around 30% bigger than monofacial.
are those good for a home system? how would i install them.

These panels can be used for residential installation, yes. However, you should follow the guidelines in the manual and check with your installer whether he had experience with bifacial modules before.
