KYOCERA Solar Modules pass Fraunhofer's high voltage stress test

Greentech Lead Asia: Kyocera announced that its solar
modules have passed potential induced degradation (PID) test conducted by
non-profit Fraunhofer Center for Silicon Photovoltaics CSP (Halle, Germany).

Fraunhofer CSP has certified that Kyocera’s modules did
not show any degradation after being subjected to high voltage stress testing.
The results of this third-party test illustrate the high quality and high reliability
of Kyocera’s modules.

“As a pioneer in the industry Kyocera has been
involved in R&D and manufacturing of solar power generating systems for
more than 35 years, and in that time we have developed numerous innovations and
manufacturing technologies to ensure the high quality and long-term durability
of our products,” said Tatsumi Maeda, general manager of the Kyocera
Corporate Solar Energy Group.

Potential induced degradation (PID) is a phenomenon where
the power output of a solar module is reduced when exposed to high negative
voltage bias between the cells and ground. PID can potentially affect the
performance of individual modules as well as the overall power output and
efficiency of an entire solar power generating system.

Fraunhofer CSP independently tested modules from 13
well-known manufacturers; subjecting the modules to a high voltage stress test
(50 deg. C, 50 percent relative humidity, -1000V, aluminum film at the front
side, 48 hours). Kyocera was one of only four manufacturers whose
modules passed the test without showing any degradation.

“With Kyocera’s solar modules having been the first
in the world to be certified by TUV Rheinland’s Long-Term Sequential Test, the
Fraunhofer CSP test results further demonstrate the industry-leading technology
and reliable performance of Kyocera modules,” Maeda added.

KYOCERA commissions fist phase of SoftBank Kyoto Solar Park

Recently, Kyocera Corporation announced the
commissioning of the first phase of the SoftBank Kyoto Solar
Park (Kyoto City, Japan). Kyocera supplied its large size, high-output
242-watt solar modules for this project.
