EL FACTS
DEFECTS DETECTED IN EL IMAGING
- Crack in solar cells
- Potential Induced Degradation (PID)
- Interconnect breakages
- Shunts and inactive areas in solar cells
BENEFITS OF EL IMAGING
- EL images are like X-ray images of the solar panels indicating internal defects
- In the absence of on-site I-V testing, EL images can identify solar panels for warranty claims.
WHY TEST PANELS?
%
More than 30% of inspected solar panels in 50+ solar PV installations across India found to have a linear degradation rate greater than 2%/year (after discounting 2% for initial LID).
%
50% more cracks observed in Young modules (less than 5 years old installation) as compared to older modules.
6 times more cracks in poorly installed power plants (having an average panel degradation rate > 2%/year).
%
13% of the inspected panels have hot spots indicative of major cracks or other major defects.
Discoloration of the encapsulant and cracks in Backsheet observed in panels from some IEC certified manufacturers within 8 years of installation.
