Anti PID Technology So that your yields don’t swerve off course
What is PID?
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”.
Trust is good, but prevention is better. For solar cells and solar modules from Hanwha Qcells, 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. The Anti PID Technology from Hanwha Qcells will save you from this fate.
Qcells solar technology "Engineered in Germany" offers more benefits besides Anti PID Technology: thanks to their marking technology Tra.QTM, Qcells solar cells and solar modules are traceable and unforgeable. The quality assurance process "Hot-Spot Protect" makes our cells and modules guaranteed hot-spot free and therefore protected against fire.
What does PID mean in terms of real use?
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 Qcells prevents PID at the cell level so that modules and entire systems permanently generate reliably high yields.
How does Hanwha Qcells prevent PID?
The Qcells’ 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-resistant. In plain English: PV systems from Hanwha Qcells generate reliable energy without any PID-affected performance loss. This means operators and installers can sit back and relax.
What is Anti LID?
Anti LID Technology is our latest innovation to extend our performance. Light-induced degradation (LID) is created by instable boron oxygen compounds. These can be found in all p-type solar cells. The exposition of this type of solar cells to sunlight leads to a substantial drop of performance of up to 6 %. Hanwha Qcells' Q.ANTUM Technology is designed to stabilize boron oxygen compounds in order to minimize light-induced degradation. This makes our Q.ANTUM solar modules more efficient than modules which are not fitted with Q.ANTUM Technology.
