So many variables and potential performance concerns with fire
damage depending of the number of modules involved, and how close
the modules were to the fire, and/or the ambient temperature and
duration to which the modules were subjected.<br>
<br>
Depending on the duration of high temperature exposure, there could
be module laminate, micro-cracking, or other mechanical concerns, as
well as PV wire and/or connector problems. None of which may show up
with a visual inspection or a simple Isc/Voc test.<br>
<br>
An Isc and Voc test would be woefully inadequate. I highly recommend
an on the ground in-situ performance assessment using an IV Curve
Tracer like a Solmetric PV1000.<br>
<br>
Where are you located? PV module / string level performance
assessment is a service my firm provides. I am located in the DFW TX
area. Please contact me off-list if you think your client is
interested.<br>

<div dir="auto">I have a client that is looking to buy some
salvaged modules off of a building that was near a fire. What
kind of potential issues can you anticipate? Smoke, heat,
etc. Would it be enough to just test voc and isc for a known
cell temp and irradiance in addition to a visual inspection or
would an iv curve trace be necessary?</div>
