Actually I am rather impressed with the performance. Around 3 - 3:15 it cleared up and was mostly sunny this afternoon. I checked the temps at approx 5:30 and it showed 147 at the collectors and 134 at the tank. I just checked and the tank is at 137. It is 73 outside and the collector is at 94 still.
Mike, the only concern I would have with these for you would be flying debris. The "panels" themselves shouldn't create too much lift with all the gaps between tubes. The install was fairly simple, I did it all by myself (could have used 2 people to mount the panels on the pole...) My only advice would be to build your own work station.

I need a MIG.... which one to buy:
I-Mig 160, I-Mig 200, or a MTS 160
