3. Our next generation solar modules are three times safer 3 PID-FREE HOT-SPOT-FREE TRACEABLE AND FORGERY PROOF

4. Potential induced degradation – a module reliability risk 4 THE PID CHALLENGE The influence of a high negative potential at the end of a string opens a leakage current path This occurs in many system installation configurations and may completely eat up your module performance over time! SOLUTION The Q-Cells Anti PID Technology (APT) prevents potential induced degradation already on cell level.

5. With APT Q-Cells prevents PID 5 After accelerated PID effect test THE SOLUTION AGAINST PID The Q-Cells R&D team has developed a fundamental understanding of the PID phenomenon and has come up with a solution to the problem The Anti PID Technology (APT)* prevents potential induced degradation already on cell level *APT Test Bedingungen entsprechen Zellen auf -600 V gegenüber dem Rahmen, feuchte Moduloberfläche, 25 °C, 300 h kein signifikanter Leistungsverlust zu beobachten

6. Hot-Spots – a module safety risk 6 HOT-SPOTS CAN LEAD TO POWER LOSS AND IN THE WORST CASE TO MODULE FIRE! Q-CELLS PREVENTS HOT-POTS WITH HSP Hot-Spot-Protect (HSP) Thanks to an industry unique testing procedure all cells are 100% checked for Hot Spots and sorted out if affected This prevents burnings and total failure of modules
