Assess the Condition of Your Solar Panels
EL imaging is a powerful, non-destructive technique that can identify otherwise undetected module issues, such as hidden micro-cracks that may cause accelerated degradation and underperformance.
EL Imaging Use Cases
EL imaging has a diverse set of use cases, including:
- Investigate cell level after IR imaging
- Investigate bad Bill of Materials (BOMs)
- Post extreme weather event ‘health’ check up
- Warranty claims
- Insurance claims
- Baseline
- Construction quality control
- Module supplier quality control
Standardization
We’ve helped propel the industry forward with standardized EL issue guides.
Example Issues Found With EL Imaging
These inspections may reveal defects and imperfections like:
- Cracks and micro cracks
- Insufficient soldering or busbar issues
- Parts of the cell that are dead (not emitting any light, hence not capable of generating any power)
- Manufacturing processing defects
- Potential Induced Degradation (PID)
- Thin-film shunting
- Fire damage
- Mismatch cells
- Factory issues
- Other cell-level issues
EL Imaging FAQs
EL imaging is a powerful, non-destructive technique that can identify otherwise undetected module issues, such as hidden micro-cracks that may cause accelerated degradation and underperformance. The principle behind EL imaging is fairly straightforward, just as PV modules produce electricity when light hits their surface, the reverse is also true—when a precise amount of electricity is injected into a module, light (in the infrared range) is emitted. EL imaging uses this to detect inactive or underperforming modules.
