Q CELLS ONLY DELIVERS TOP QUALITY
Modules from Q CELLS are one of the most efficient and profit-yielding on the market world wide. We offer outstanding power classes and cutting-edge technology. We were one of the first to develop a solution for common module problems such as Hot-Spots and potential-induced degradation (PID).
- Q CELLS is synonymous with German Engineering and the skill of developing high-quality solar PV solutions.
- The Q CELLS Triple Yield Security guarantees peace of mind regarding PID, Hot-Spots and forgery.
- The Q CELLS Q.ANTUM cell technology with efficiencies of up to 19.5 % proves that we took the next step to a high performance and cost-effective cell generation.
- ANTI PID
- HOT-SPOT PROTECT
ANTI PID TECHNOLOGYSO THAT YOUR YIELDS DON'T SWERVE OFF COURSE
For solar cells and solar modules from Q CELLS, potential induced degradation (PID) doesn't exist. Potential induced degradation can lead to a performance loss of 20 % or more, even in the first few months. Hanwha Q CELLS´ proprietary Anti PID Technology will save you from this fate.
Based on the way conventional photovoltaic systems work, voltage differences occur between the frames and the solar cells of a module. Especially in wet weather this can lead to undesired leakage currents which can decrease the performance of the cells. According to a report by the industry journal Photon (Dec 2010), this can result in yield losses of 20 % or more. This effect has been named "Potential Induced Degradation", abbreviated "PID".
Progressive performance losses decrease a system's yield and this often leads to high claim rates for module manufacturers and installers. Plus, proving PID is a very complicated and costly process. Hanwha Q CELLS prevents PID at the cell level so that modules and entire systems permanently generate reliably high yields.
Hanwha Q CELLS' proprietary Anti PID Technology (APT) optimizes the cell production process so that the negative effects of leakage currents are already eliminated at the cell level. This makes both our solar cells and our solar modules PID-resistant¹. In plain English: Q CELLS PV systems generate reliable energy without any PID-affected performance loss. This means operators and installers can sit back and relax.

HOT-SPOT PROTECT PREVENTS SOLAR MODULE FIREQ CELLS SOLAR CELLS AND MODULES ARE GUARANTEED TO BE HOT-SPOT
FREE – MODULE FIRES ARE OUT OF THE QUESTION
Solar cells with Hot-Spots can heat up to such a high temperature that parts of a module burn out. In the worst case scenario, a module can catch fire.
The Hanwha Q CELLS team makes sure that our Q CELLS products guarantee a very high level of reliability and safety. Thanks to our advanced production process we are able to keep cool about Hot-Spots. We only ship and process solar cells that are 100 % Hot-Spot free.
During different production steps, the primary material of solar cells – the silicon wafers – are subject to both chemicals and severe heat of up to 900 ℃. They are also put under mechanical stress during transport. Together these factors can lead to very small material defects – so-called "micro cracks" – that cannot be seen during conventional final inspections. Defective edge insulation can also cause Hot-Spots.
Hot-Spots really pop-up when modules are in partial shade. When one cell in a module is shaded (e. g. by an antenna, chimney or dirt), it doesn't generate any current, but the rest of the cells in the module continue to work. This leads to reverse currents that prefer to run over the Hot-Spot area where they meet less electric resistance. Then, caused by this strong, isolated stress, parts of the Hot-Spot area can heat up to over 250 ℃. At this point, the cell can burn through. In the "best case" scenario, this only leads to continual yield loss, but in the worst case scenario the module can catch fire.
To decrease the risk of Hot-Spots, many manufacturers simply lower the so-called breakdown voltage of the cells. This does reduce the maximum level to which a cell heats up, but it also reduces the cell's performance. At Hanwha Q CELLS, however, a reverse current is put through all cells during the final inspection stages. An infra-red camera then shows any Hot-Spot as heat spot. Cells with Hot-Spots are then sorted out and recycled. The result is that our solar cells and modules are Hot-Spot free. With our Hot-Spot Protect, Hanwha Q CELLS is the only PV company that is able to sort out all Hot-Spot affected cells across the board in order to provide solar owners with the ultimate level of protection.
THE VEHICLE IDENTIFICATION NUMBER OF YOUR CAR IS ITS FINGERPRINT
Tra.Q™ IS THE IDENTIFICATION TECHNOLOGY FOR SOLAR CELLS
Every Q CELLS solar cell has its own unique code. Every photovoltaic cell is thus traceable and guaranteed to be the real thing.
The Tra.Q™ code contains information about the place and date of production. This makes it possible to trace certain production conditions for each solar cell.
When you buy fruit at the market you have the right to know where it was grown. We think this same principle should apply to solar cells and modules. You can feel secure knowing that you have bought a genuine Q CELLS product – and this also makes it possible for us to both keep an eye on and optimize our production processes. Traceable Quality (Tra.Q™) enables us to completely trace the entire manufacturing process for each individual solar cell – this includes the serial number, the date and location of production and even which material charge was used to make the cell. We can thus better analyze errors and even improvements as they arise and integrate them into our development process.
Solar cells are the heart of any PV facility. There are now hundreds of solar cell manufacturers – including brand-name companies – whose cells are made all over the world, and, unfortunately, product piracy has also hit the photovoltaic industry. How can you know exactly whose heart is actually beating in your module? We know for sure what's in ours and we can prove it beyond a doubt. Q CELLS solar cells that carry the Tra.Q™ label can be clearly identified. This ensures transparency and means you can count on secure yields thanks to Hanwha Q CELLS´ proprietary Tra.Q™ labeling technology.
With Tra.Q™ every wafer is labeled with a unique code. Thanks to specially-developed laser technology, the wafer isn't damaged in this process. The code can then later be read with a special device. Tra.Q™ is like a fingerprint for a solar cell. At the moment, Hanwha Q CELLS is the only solar cell manufacturer to offer the patented Tra.Q™ labeling technology.
