Cell technology

Q Cell’s Q. Power series is the best of their polycrystalline modules. The panels embrace the evolving polycrystalline technology and the 6-busbar technology, significantly improving its power yield.

The cells use anti-LID & PID technology to reduce Light-induced and potentially-induced degradation, which might affect your system performance.

The blend of these technologies improves the panel’s reliability and efficiency.



The Q. Power series solar panels maintain a 97.0% nominal power output during the

first year. After 10 years, this output efficiency declines to about 91.6%, then at least 83.0% of its rated power output by the 25th year.

The degradation rates for these series stand at 0.6% annually, slow enough to ensure faster ROI on your investment.

Warranty/ Guarantee

Q Cells assures you that this product is a reliable investment by offering a 12-year product warranty – which is two years longer than the standard 10-year warranty.

They also offer a 25 year linear performance warranty that is now becoming the industry standard.


Peak Performance

In ideal conditions, the maximum output of the Q. Power series panels is around 280W with an efficiency of up to 17.4%. The panel’s heat tolerance is also good (-0.40%°C), and its performance in extreme weather conditions is impressive.

Panels needed for 6.6kW solar system

You will need around 24 solar panels for your 6,600W solar system. This series is best for homeowners with ample roof space or ground land for the installation.

Q. MAXX solar panels also use anti-PID technology, anti-LID technology, and Tra.Q™ for tracing, and hotspot protection.


Q cells assure you of a 98% nominal power output in the first year and a 0.54% annual degradation afterward. During the first 10 years, the panels’ power output stands at 93.1%. After 25 years, you can expect at least an 85% power output of its initial ratings.

Warranty/ Guarantee

Unlike the Q. Peak extended warranty guarantee, Q. MAXX maintains a 12-year product and a 25-year performance warranty. This shows that Q Cells backs its product well.

Peak Performance

The maximum power output of the Q.MAXX series panels is 360W, with an efficiency of 20.1% in the best conditions. The panels are versatile and can accommodate harsh weather conditions thanks to their high-quality alloy frames and wind and snow loads of 5400/2400 pascals.

Panels needed for 3kW solar system

To install the Q. MAXX solar panels on a 3kW solar system, you’ll need about 10 solar panels. This makes these panels a good choice for residential homes and buildings with small roof spaces.

Latest leap forwards for Q Cells solar panels

Q Cells has been a leader in the solar industry since its founding in 1991 in Germany.

In 2007, this solar company started developing the Q.ANTUM technology, the advanced PERC technology for their panels. Later in 2012, Q CELLS became the first solar panel manufacturer to begin mass production of solar panels using the innovative PERC technology.

The company’s proprietary Q.ANTUM technology has since been improved into Q. ANTUM DUO technology involving MBB design, half-cell, and wiring interconnection.

In 2019, Q Cells released the Q.PEAK DUO-G9 series, which uses the Q.ANTUM Z Technology (Zero-gap technology). Q CELLS, a technology leader in the solar energy industry, has continued to build its brand in the market through its breathtaking technological breakthroughs. The company is now developing perovskite tandem cell and N-type cell technologies.

Q CELLS Solar company has a solid foundation in the solar manufacturing business, and they are now expanding into energy storage solutions, energy retail, and downstream development.

Why Q CELLS solar panels?

When it comes to new solar technologies, no company outpaces Q Cells. The company has invested heavily in R&D with around 4 state-of-the-art Research and development centers.

This allows them to continuously improve their products, ensuring that customers only get the best.

Their 12-year product and 25-year performance warranty, combined with an efficiency of up to 19.5%, also mean a reduced payback period.

Q Cells also offers a wide range of solar panels, giving homeowners the freedom to choose the best panel series for their property.

Cell technology

Q Cells uses their own technology, Q. ANTUM solar cell technology, in all their solar panels. This technology is based on the PERC technology (Passivated Emitter Rear Cell) and is only improved by a special Nano coating.

The coating works like a regular mirror, reflecting the otherwise unused sun rays to the cell, increasing its sunlight absorption.

The panel also comes with laser-fired contacts that enhance the cell’s electrical properties, increasing its efficiency incredibly.

Newer Q Cell Peak series models also use busbar technology and half-cut cell technology to reduce internal power losses and increase output.

Other technologies integrated into the solar panels include the anti-LID (Light-induced degradation) technology, anti-PID (potential Induced degradation) technology, Hot Spot Protect, and the Tra.Q™ technology used for panel tracking.
