Qcells technology We strive for the next innovation

Our solar modules are among the most powerful and profitable on the market worldwide. We offer the highest performance classes and have developed solutions for technological problems such as hot-spots and potential-induced degradation (PID) so that you can produce solar power effectively and safely.

Trust Qcells solar technology

  • Qcells is German engineering at our home site in Bitterfeld-Wolfen, Germany.
  • The Qcells yield guarantee relieves you from worries about potential-induced degradation (PID), hot spots and falsifications. We will supply you with safe solar technology that provides great performance. During an industry-wide research, conducted by the Fraunhofer CSP, 9 out of 13 modules from renowned manufacturers showed drops in performance in the PID test.
  • On average, the drop amounted to 56 %! After the test, Qcells modules still delivered 100 % performance.
  • With its new Q.ANTUM technology, Qcells has taken the next step to a high-performing and cost-efficient generation of cells. "

Q.ANTUM DUO Technology Uncompromisingly efficient

Qcells solar modules with Q.ANTUM DUO Technology not only deliver impressive performance in real-world conditions, but also offer first-class performance guarantees of 98 % in the first year and a full 86 % after 25 years. The Q.ANTUM DUO Technology combines our Q.ANTUM Cell Technology with the innovative DUO cell separation method: The use of round connecting wires and zero-gap cell interconnection ensure higher power generation not only in the laboratory but also in everyday operation.

Q.ANTUM DUO also increases the nominal power and improves the reliability of the module thanks to Qcells Yield Security consisting of Anti PID, Anti LID / LeTID as well as Hot-Spot Protect and TraQTM. With more than 23 GW of Q.ANTUM solar cells produced, only Qcells has the experience and knowledge to drive the development of cell and module technology and launch new technologies such as Q.ANTUM DUO.

Hot-Spot Protect

Solar systems and modules fitted with genuine Hanwha Qcells reliably eliminate one hazard for modules catching fire. Our quality assurance system "Hot-Spot Protect" guarantees that solar cells and modules delivered by us are free of hot spots which may heat the equipment and in the worst case cause the module to catch fire.

Anti PID / Anti LID To keep your yield on track

Potential-induced degradation may cause up to 20 % loss of yield already after only a few months of operation. With Anti PID technology from Hanwha Qcells, you are protected against this loss.

Tra.Q If it says Hanwha Qcells, it is Hanwha Qcells.

With our patented marking technology Traceable Quality (Tra.Q™), we were the first manufacturer to introduce a system that allows to trace every Qcells cell reliably and seamlessly.

R&D history

Our headquarters for technology and innovation in Thalheim, Germany, is uniquely equipped with everything needed for research and development as well as pilot projects and testing. This is how we can develop high-tech products and innovative production processes.

Thanks to this unique concept, we are able to introduce technologic innovations quickly into the series production. This way Hanwha Qcells frequently sets the bar for the industry, for example, with the 6-inch solar cell, the fully squared mono-crystalline solar cell or the Q.ANTUM cell technology.
