Review: Q.PEAK DUO-G6+ solar panel from Q Cells

Published: 18 May 2021

A closer look at Q Cells’ Q.PEAK DUO-G6+ panel, a panel that has an advanced design to produce more electricity than other panels of similar size.

At Nectr we have a business partnership with Q-Cells, a Tier 1 solar manufacturer with global presence. One of their main products we use is the Q.PEAK DUO-G6+ solar panel, which uses an advanced design to produce more electricity than other panels of similar size.

Q.PEAK DUO-G6+ solar panels are available in four wattages: 340W, 345W, 350W and 355W. Home solar panels normally have 60 photovoltaic cells, but this panel uses 120 half-cells instead. They use the Q.ANTUM technology, which was developed internally by Q Cells. Thanks to this innovative design, electricity is generated and conducted more efficiently, boosting the solar panel’s performance by 3%.

Q Cells have been in the Australian market since 2009. Q Cells created the Desert Knowledge Australia Solar Centre (DKASC), where their panels have been tested since 2012. This guarantees high performance even under the harsh desert conditions of the Outback.

Advantages of Q.PEAK DUO-G6+ solar panels

Q.PEAK DUO-G6+ solar panels use monocrystalline cells. These are the most efficient cells, and they are characterised by their black color. The energy output of each solar panel is further increased with an innovative design:

  • There is a reflective coating behind the solar cells, which maximises the amount of sunlight converted into electricity.
  • The Q.PEAK DUO-G6+ uses 120 half-cells, with an innovative wiring design that reduces losses, instead of the typical 60 cells of residential solar panels.

With a rated power of 340W – 355 W and dimensions of 174cm x 103cm, this solar panel uses the roof area very efficiently. This is a major advantage in homes with limited space for a solar power system. For example, you only need 15 of them for a 5-kW installation, and they only cover an area of 27 square metres.

The Q.PEAK DUO-G6+ solar panel has a tough construction, and it can withstand severe weather conditions like high winds and heavy snowfall. These solar panels also come with a 25-year warranty, while achieving a typical payback period of less than five years in Australia. Q Cells guarantees that their solar panels will have at least 85% of their initial capacity after 25 years, making them a safe investment.

Q.PEAK DUO-G6+ panels have the CE and VDE electrical safety marks, which are only awarded after rigorous testing under laboratory conditions. Q Cells solar panels are engineered in Germany, where the company has the largest module testing centre in the world.
