I got this to use in the hot sun of the black rock desert. It performed as well as I expected. My only criticisms are that if even a single finger is in front of part of the panel it completely cuts all power (but I think is the same with all panels) and the output was pretty far off from the specifications. This may also be normal but I put on a voltage regulator chip (~$1 at radio shack) because it was putting out almost 20V and I only wanted 12V.
Worked great to charge my phone or run a 12V fan.
