PV Evolution Labs Certifies Solar Manufacturers as PID-Free: Yingli,
SolarWorld, JA Solar, Kyocera, and Trina All Pass Qualification
Stringent Potential Induced Degradation Testing Provides Confidence of PV
BERKELEY, Calif. -- December 11, 2012
North America’s premier independent solar module test lab, PV Evolution Labs
(PVEL), announced that under its new Potential Induced Degradation (PID)
testing program, several leading solar PV manufacturers have received the
highest level of certification as PID-free. PVEL created the PID Certification
program because it is now known that the electrical potential between the
frame and cells of a PV module can cause accelerated performance degradation.
The most recent manufacturers to be qualified by PVEL’s stringent
Certification are Yingli Solar, SolarWorld, JA Solar, Kyocera Solar, and Trina
“Sophisticated module testing and characterization is about realizing the
benefits of good design,” said Jenya Meydbray, CEO of PVEL. “Our PID
Certification provides manufacturers and project investors with detailed
intelligence about how PV products withstand a common cause of performance
degradation and module failure.”
PVEL develops innovative new testing programs in order to increase PV quality
standards within the industry and mitigate technology risk for project
investors, particularly in areas such as the PID phenomenon, where there are
no industry-wide acknowledged test standards available. By measuring the
stability of solar panel electrical output when exposed to high system
voltages (positive and negative 1kV) under harsh environmental conditions
(85˚C at 85% relative humidity) for 600 hours, PVEL engineers determined that
the modules tested performed far better than the allowable degradation limit.
In simulating system voltage stresses that an installed module endures and
evaluating both positive and negative grounding effects, manufacturers and
power plant owners have more confidence in PV module reliability knowing the
modules are being deployed in appropriate system configurations.
Headquartered in Berkeley, CA, PV Evolution Labs (www.PVEL.com) was founded on
the principle that understanding solar module performance and aging behavior
through rigorous testing is fundamental to reducing risk in solar investments.
PVEL enables realizing the benefits of good design.
