We have a couple of these cameras and they are very handy.<br><br>
These cameras are also good for detecting high currents through fuses (if
you can see the<br>
fuses) and bad connections, etc.<br><br>
We had a Chinese module laying around (Astronergy 250W) and it was
sunny so I took a<br>
few pix. Short circuit and open circuit.<br><br>
You can see at least 15 to 20 degrees C difference sometimes.
I will have to check<br>
some other modules but I don't know if any manufacturers match cells
?<br><br>
These pix are from the back of the module. You have to be careful
of reflections more<br>
from the front. <br>
The temperature at the top-left is where the crosshair cursor is and
the<br>
right scale is maximum (whitest) temperature and lowest (darkest)
temperature<br>
in view.<br><br>

Here is one with the module open circuit. Note high and low
temperatures are around 44 C.<br><br>

Flir E40, works well and has some good features that make it easy
to write reports with the software. E60 is similar with additional
features, but a little more expensive. IMHO any of the E - series
is a pretty good bet. <br>

What kind of thermal camera are you using for this kind of inspection?
Satisfied? Comments?<br><br>
Thanks,<br><br>

Loaded modules will have hotter cells. I know this from searching for bad
cells with a thermal camera. At open circuit I could not see a
difference, but short circuit or loaded I could see 20 - 30 C increase in
mismatched cells .<br><br>

<dd>Folks,<br><br>
<dd>Two identical PV modules are mount in an identical fashion and
exposed to identical irradiance.<br><br>
<dd>One module is open circuit. The other is connected to a load and
producing power.<br><br>
<dd>Is there a difference in the temperature of the two modules? If so,
which one is cooler?<br><br>
