Review: Q.MAXX-G2 solar panel from Q Cells

Published: 31 May 2021

A closer look at Q Cells’ Q.MAXX-G2 panel, a panel that uses Q.ANTUM technology to increase electricity production and increase power bill savings.

At Nectr we work with the best brands in the industry. Q Cells are a Tier 1 manufacturer who supply solar panels around the world, and their Q.MAXX-G2 panels are one of the main products we use for residential installations. These panels use the Q.ANTUM technology developed by Q Cells, which increases electricity production and power bill savings. 

Solar panels from the Q.MAXX-G2 product line come in four wattages: 345W, 350W, 355W and 360W. Residential solar panels are composed of 60 cells, but the Q.MAXX-G2 has 120 half-cells with an improved wiring design. This increases the power output by 18%, compared with panels that use normal solar cells.

Q Cells have served the Australian solar market since 2009. The company owns the Desert Knowledge Australian Solar Centre (DKASC) in Alice Springs, where their solar panels have been tested successfully under desert conditions since 2012.

Advantages of Q.MAXX-G2 Solar Panels

Q.MAXX-G2 solar panels are made of monocrystalline cells, having a higher efficiency than polycrystalline and thin-film panels. Their performance is further improved with the innovative Q.ANTUM design:

  • The solar cells are mounted above a reflective coating. Sunlight that is not converted into electricity is reflected back into the cell a second time, increasing the energy output.
  • The layout of 120 half-cells with efficient wiring can convert sunlight into electricity with higher efficiency, compared with a typical 60-cell home solar panel.

Having an output of 345W – 360W and measuring 174cm x 103cm, the Q.MAXX-G2 uses roof space very efficiently. This is especially useful when a home has limited space to install solar panels. For example, a 6-kW installation only requires 18 of these solar panels, covering less than 33 square metres.

Q.MAXX-G2 panels are also designed for harsh environmental conditions, withstanding heavy snowfall and strong winds. These panels have a 12-year product warranty that covers material and workmanship defects, and a performance warranty of 85% nominal power after 25 years. With the abundant sunshine and high electricity prices of Australia, solar panels have a payback period of less than five years for most homes. Since their warranty is much longer, the return on investment is assured.

Q.MAXX-G2 solar panels have CE, VDE, and TUV markings. Electrical products must pass demanding laboratory tests to earn these marks, which guarantee quality and electrical safety. The Q Cells technology and innovation headquarters are located in Germany, where they also own the world’s largest solar panel testing centre.
