About product

Among the newest offerings of Q CELLS, QPDB-G5 320W is part of the Q.PEAK DUO BLK-G5 series. These panels use state-of-the-art technology to achieve high efficiency and dependability. Q.ANTUM is an advanced PERC technology developed by Q CELLS. The company employs a special nano coating on the rear of the cells to reflect the sunlight back and generate more electricity.

The use of half-cut cell technology is an additional perk. The solar cells of QPDB-G5 320W are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life and enhanced efficiency in low-light conditions. Given its size and weight, QPDB-G5 320W efficiency of 19% is quite impressive. The innovations made the appearance of the panel as impressive as the specs. A mere 1.26" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. Q CELLS offers 12 years of product warranty and guarantees 85.04% of original performance after 25 years of operation.

  • 320 W power output
  • 120 half-cut Q.ANTUM cells
  • 19% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 25-year performance warranties

More energy and efficiency

The Q.ANTUM technology further improves an already excellent efficiency of 19 percent. A reliable PID resistance and a unique glass lamination were added by the maker, which ultimately produced a model that was effective and extremely durable. QPDB-G5 320W produces 320 W of power under typical test settings.

Heat-resistant performance

This module makes the heat less dangerous since it has one of the lowest temperature coefficients in the market, losing just 0.28% of efficiency for every 1.8°F over 77°F.

Quality and reliability

QPDB-G5 320W undergoes various quality checks during the production process and is subjected to serious quality and reliability testing. Manufacturing facilities are highly automated, removing the possibility of human errors. Q CELLS is committed to quality, safety, and dependability to ensure you get the finest.

Reliability and degradation resistance

Q CELLS guarantees slow deterioration over the next 25 years. The performance will decline by no more than 2% during the first year and then by no more than 0.54% every year after that. After the 25 years are over, your modules will retain at least 85.04% of their original performance. This 320 W Q CELLS solar panel also comes with a substantial 12-year product warranty.

A panel that can handle hail, wind and snow

The 1.26" 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 5400 Pa load, and the back side 4000 Pa.

Outstanding all-black design

The panel has a sleek, all-black style that complements any roof beautifully. Q CELLS uses unique treatment and selection procedures to guarantee optimum cell color. The cells are connected by thinner wires, and from a distance, the surface of the modules seems seamless and smooth.

These Q Cells panels are sleek, efficient, and generate energy even on cloudy days. We have noticed a significant decrease in our energy bills since we installed the system. We would highly recommend this solar panel to anyone who is looking for a reliable and high-performing option at a very attractive price.

I recently purchased a few of these Q CELLS 320W Solar Panels for my home pool and I am extremely satisfied with their performance. As an engineer, I appreciate the high efficiency and durability of this model. The sleek black design also blends in nicely with my home's aesthetics. The thing the spoiled the fun a little was a single cracked panel at the bottom. At least A1 replaced it without hassle. The transportation service should be more careful

It's compact, efficient, made by a German quality and only a little above $200. Pure gold.
