<div dir="ltr"><div><div>Thanks all! <br><br>Jeff - I like the price point on that Fluke
VT02! It seems like it would do the trick for most electrical
applications. Have you tried locating hot spots on modules with it?<br><br></div>Bill - The Flir E-series looks awesome but is a little out of my price range. I looked at that SEI course but it just completed. However, I see that you are one of the instructors! Any idea when the next class will be? Is there any way for me to access the course materials?<br>
<br></div>Randy - The Flir i7 clearly can handle both the electrical and the module hot-spot duties. Thanks for the great image!<br><div><div dir="ltr"><div dir="ltr"><br><div><br></div><div><div><p class="MsoNormal"><span style="color:rgb(0,102,0)">For a brighter energy future,<br>

Wrenches - I am considering the purchase of a thermal imaging camera for PV system commissioning applications. Prices seem to range from $1,000 to $10,000+. Primary manufacturers seem to be Fluke and Flir, with Extech, Ideal and Milwaukee offering a few products as well. It seems to me that the key factors to consider are temperature range, thermal sensitivity, screen resolution, screen size, battery life, type of image capture and price. Does anyone have experience with using thermal imaging to identify temperature irregularities in modules and/or electrical equipment? What temperature range, thermal sensitivity, and screen resolution is needed for both/either of these tasks? What have been the key factors/specifications in terms of ergonomics and functionality? Any preferences in terms of manufacturer?<u></u><u></u></p>
