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

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?

Good day. One pallet can fit 27 modules and its weight is going to be 1500 lbs.
