QSAR II modules successfully tested according to the Chemitox PID (potential-induced degradatio

CSUN, a specialized manufacturer of solar cells and modules announced  that first samples of its new high efficient QSAR II modules were successfully tested according to the Chemitox PID (potential-induced degradation) standards.

Chemitox is an independent testing laboratory headquartered in Tokyo, Japan an important institution for securing PV module quality employed on the growing Japanese market.

While the industry is still trying to fully understand the PID phenomenon, CSUN has started a comprehensive testing cycle to determine and enhance the quality of its product portfolio.

As the IEC 62804 “System voltage durability test for crystalline silicon modules” is under discussion, CSUN has classified the test conditions according to its severity in four grades:

- Severity I with test conditions of 25°C / -1000V / 168 hours and the module surface covered by aluminum foil – the socalled TÜV Rheinland standard

- Severity II with test conditions of 60°C / 85% RH (relative humidity) / -1000V / 96 hours – the so-called TÜV Süd Standard on which also the IEC 62804 is based

- Severity III with test conditions of 85°C / 85% RH / -1000V / 48 hours – the so-called PI Berlin standard

-Severity IV with test conditions of 60°C / 85% RH / -1000V / 96 hours and the module front surface immersed in water – the so-called Chemitox standard

Initial test of CSUNs high efficiency QSAR II modules show that this module type has the potential to not only fulfill the IEC 62804 standard but can withstand harshest PID test conditions as simulated by the Chemitox laboratory standards. While first tests at the Chemitox labs showed power loss results between 4.3% and 6.6%. More severe in-house testing is still ongoing, showing similar results as the Chemitox data.

The CSUN research and development team is taking these promising results forward to further improve the long-term durability of CSUN’s high efficiency QSAR II modules, highlighting CSUNs tireless pursuit of product quality.
