Electroluminescence imagining

Location: Bahawalpur, Pakistan
Test type: Electroluminescence Imaging
Risk: Potential Damage to PV Modules
About Us
3
A 100 MWp PV project was installed in Bahawalpur, Pakistan. Commissioned in 2015, the
plant contributes 100MWp of power into country's national grid.
During the construction phase, a severe sand storm hit the region. Due to high winds, some
PV Modules that were improperly installed fell off the mounting tables. There was a high
chance that the PV cells in these PV modules have suffered serious damage as a result of
the fall.

In order to verify this, the panels were transported to our testing facility for EL imaging. The
damaged panels were to be replaced so each PV array would continue to function normally.

All Panels were visually
inspected before
subjecting to EL imaging.
As in most cases, it is
difficult to identify damage
to the cells within the
modules without proper
imaging.

Upon EL imaging, it was
observed that there was a
significant damage to the
cells in some panels.
Multiple cracks and large
inactive regions meant
that these panels will
function poorly if installed
in a PV array and would
decrease the performance
of other modules within
that array.
