Solar panel selection is one of the more daunting buying decisions your going to have to consider. Then, make your selection process a little easier! If you’re in the market for a highly-regarded solar module range offering good overall value, consider QCells solar panels.

.Manufacturer:  Hanwha QCells.

Series: Q.Power, Q.Peak, Q.MAXX.

Variants: Multicrystalline, Monocrystalline.

Navigating the QCells range for the novice can be a little confusing, so here’s the low down. All models start with the letter Q (Q.Power, Q.Peak, Q.MAXX, etc.). 

Despite all the Q’s your about to be introduced to, here’s how to simplify your exposure to the QCells solar panel range. 

If it’s a highly regarded solar module with affordability at the forefront of your buying decision, consider the Q.Power multicrystalline range.

However, If you’re a little short on space and require maximised power output, the premium Q.Peak and Q.MAXX monocrystalline range provide the modern efficiencies desired by many.

No matter your preference, the QCells solar panels available in 2020 stem from innovative designs which have claimed industry honours over the last decade.


When you’ve got an abundance of space to accommodate your desired solar array size and looking for the most affordable QCells solar panel option, the QCells Q.Power-G5 hit’s the mark.

No matter the cell structure, the test of a well designed solar module is its ability to endure time. As a Photon “Best Polycrystalline Solar Module 2014”, the QCells Q.Power-G5 is a testament to such an enduring design combined with a more budget-friendly multicystalline cell design.

QCells Q.Power Panel


As with many mono vs multicrystalline options the QCells Q.Peak range (which is monocrystalline) provides QCells most efficient solar modules.

An evolution of the premium Q.Peak range in 2018 saw the release of the QCells Q.Peak Duo-G5 which, much like it’s multicrystalline counterpart, claimed another top industry award for innovation-the highly coveted InterSolar Award. 

For added assurance, “plus” variances released in 2019 to selected international markets extended the Q.Peak Duo G5 & G6 product warranty from 12 years to 25-years. A move to further define the premium nature of this award-winning product line. 


Model Qualities Rank Detail
290-310W, white back sheet, full cell, max efficiency 18.9%
3.7 very good
Q.Peak Duo-G5+
315-335W, white back sheet, split cell, InterSolar award, max efficiency 19.9%
4.1 superior
Q.Peak Duo-G6+
340-355W, white back sheet, split cell, max efficiency 19.9%
4.1 superior

The Q.MAXX is almost the same solar module as the Q.Peak Duo-G5. However, the Q.MAXX expands on the six wire busbar format of the Q.Peak Duo-G5, doubling the busbar technology to 12. 

Aside from a minimal efficiency increase, the QCells Q.MAXX solar panel range is near identical, lacking that of the extended product warranty period of the QCells Q.Peak Duo G5+.

3.9 superior

QCells Q.ANTUM Duo Image


What is noticeable among all QCells solar panels, no matter the model, is a unique premium feel/ finish, which can’t be gauged by specifications. Increasing the overall product warranty in selected premium models will assist the justification of this, though. 

Confusion for many end-users potentially exists between Duo-G5+, Duo-G6+ and Q.MAXX models as the differences in design and efficiency are all very similar. Each serves an advantageous purpose though given the scenario and local professional insight should never be discounted to assist in deciding on the ideal solution.

Overall, QCells offer a SUPERIOR solar module range in 2020, missing one crucial offering. A solar panel available in the 20%+ module efficiency class. With this in mind, could a new release be expected later in the year? Or a maybe a slight design tweak for an efficiency boost to an existing model? Time will tell.
