EL Testing Service
PV panels can have various defects which result in yield loss. An outdoor electroluminescence test provides a meaningful snapshot or health record of the PV modules and therefore offers a reliable solution for owners, EPCs, investors and O&M providers.
What is
Electroluminescence ?
Photovoltaic (PV) cells are based on semiconductor technology and generate electricity when illuminated. This process is called electroluminescence (EL). In common, The EL measurement detects otherwise invisible PV defects such as cell cracks, contact problems, inactive cell parts, early-stage PID, and LeTID.
Why is outdoor
EL special?
01
BE THE STATE OF THE ART SOLUTION
Electroluminescence is the most detailed optical testing method when examining PV module anomalies and their origins.
02
BE THE BASIC OF EVALUATION OF SAT
Samples of the delivered PV modules are checked after arriving on-site in a Site Acceptance Test (SAT) based on EL for new utility-scale PV projects.
03
SAVE MONEY ON DELIVERING SNAPSHOT
Outdoor EL is a cheaper and more reliable method to deliver a meaningful snapshot of the power plant’s module health.
04
EXACTLY VISUALIZE IMPORTANT DEFECTS
EL can visualize important defects that are invisible to the eyes or thermographic inspection methods before warranties are expired.
Why is EL important?
Easy to spot major faults
Thermography is a great tool to spot major faults such as lost substrings, inactive modules, or hot spot patterns.
Reduce construction & labour cost
Outdoor EL gives a hand reduce labour hours and the risk of module failure compared to previous methods in the past.
