CSUN, a specialized manufacturer of solar cells and modules is announces 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.
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 CSUNs high efficiency QSAR II modules, highlighting CSUNs tireless pursuit of product quality.
