Suntech Modules Excel in Independent PID Test
Suntech Modules, Tested by VDE, Highly Resistant to Potential-Induced
SAN FRANCISCO, Oct. 31, 2012
SAN FRANCISCO, Oct. 31, 2012 /PRNewswire/-- Suntech Power Holdings Co., Ltd.
(NYSE: STP), the world's largest producer of solar panels, today announced
that its Wd poly, Wd mono and Ve poly series modules are highly resistant to
potential-induced degradation (PID) as confirmed in recent tests performed by
the Association for Electrical, Electronic and Information Technologies (VDE),
one of the world's leading testing and certification institutes.
According to the VDE test report, the tested Suntech modules "show no
significant degradation at the end of the test sequence..." with all of the
modules exhibiting negligible change in output power within the test lab
measurement accuracy, and no changes in visual appearance.
"This near-perfect result meets our quality expectations," said Stefan
Jarnason, Technical Director at Suntech Power Australia and one of the world's
foremost experts in module reliability testing. "Amidst a highly-competitive
global market, Suntech continues to focus on helping customers achieve a
better levelized cost of energy and long term energy yields instead of just
lower sticker prices."
The stringent PID test sequence, which is based on the protocol established by
TUV Rhineland, begins with flash-testing the modules to determine their
electrical performance characteristics, as well as an inspection using
electroluminescence (EL) imaging. Then, the modules are subjected to high
humidity and negative voltages of 1000 volts for one week. Finally, the
modules are again tested for electrical performance and for any visual defects
using EL imaging.
Solar systems often operate in difficult environmental conditions with the
potential to stress the photovoltaic modules and accelerate module
degradation. Through careful and diligent material selection, manufacturing
processes, and quality control procedures, Suntech significantly reduces
performance risks associated with PID.
