Regarded as an “Engineered in Germany” solar panel option, QCells were once the German-made industry darling for those seeking the ultimate in long-term solar quality. Now accompanied with a decade of evolution, what is the truth behind the many QCells solar panels, their origin and which QCells choice likely to work best with your specific installation?

INSIDE!

Consistently a top 5 BNEF Tier-1 solar panel manufacturer, QCells provides a very diverse range of solar panels which are likely to appeal to most budgets. There are, however, some very big overall product differences worth considering before deciding which QCells solar panels are ideal for you.

Which to avoid?

In most instances, 72-cell (144 half-cell) solar panel variants for residential installations. 72-Cell QCells solar panels are built by the manufacturer with a primary purpose catered toward larger, more supportive commercial rooftops and infrastructure.

Often peculiar cases exist where certain installers or retailers may promote such solar panel variants as ultra-high powered options. However, these are often derived from a lower wholesale price per/watt due to stock oversupply after commercial shipments have been fulfilled. 

These higher wattage panels are no more efficient than 60-cell (120 half-cell) QCells solar panels and simply occupy a greater surface area per panel. The result is an equal solar array footprint with potentially less desirable side effects in residential circumstances.

Where are they made?

Malaysia: After being acquired by Hanwah in 2012, the QCells German solar panel manufacturing plant relocated in 2015 to Malaysia to better compete on a global scale and ensure long-term financial stability of the well regarded muticrystalline solar panel range.

South Korea: Premium Q.Peak range of QCells solar panels are built in QCells latest production facility within South Korea. A site dedicated to producing modules incorporating high-performance monocrystalline solar cell foundations. An excellent example to such an innovative facility is the QCells QPeak Duo-G5 claiming the industries top prize for innovation in 2018 (InterSolar Europe Award).

China: The consolidation of Hanwah’s Chinese manufacturing brand in 2015, SolarOne, ensured all Hanwah assets now operate under the one QCells banner. A formation facilitating 3 key manufacturing locations for customised product lines.

Despite the relocation of production lines, QCells has retained most German based R&D facilities. A result which has ensured the product across all manufacturing plants remain true to the original design origin.
