I'm in eastern North Carolina. I tested these panels when they arrived new and got between 165 and 180 watts output. Had not thought about ut still being in the winter season. Thanks.

I freely admit, I did not do my homework when I had these panels installed on my metal roof, and it has cost me dearly. Thought I did my research, but that was not the case. Originally, they were installed down pretty close to the roof itself. Then, I had some spacers made from 2" aluminum...

I'm in North Carolina, not far from the coast, and we typically see one serious hurricane every other year or so.

Thanks, man.

Angle may have been off a little, but the panels faced the same direction as they would when mounted on the roof. Plus, it was late winter/early spring when I tested them.

Square tubing in 4" sections as a spacer for each bracket.

Thanks. Wish I had kept a better eye on this thread. They are installed on a metal roof. Total clearance would be 2" from the spacers, and 5/8" more from the mounting brackets. Should that be enough, or do I need another 3/8" or so? Also, what does NEC/NFPA stand for?

Not using any framing. Panels are now screwed directly into the metal roof. Thanks for your response.

Thanks for the input so far on reducing heat issues. I have the two inch aluminum square tubing on hand and ready to install, but when I finally heard back from Renogy, they suggested placing some insulation between their 200 watt panels and the metal roof beneath. Does this make any sense? If...

I believe I'm all set, with 1 possible exception. 3M has what appears to be the best option for some barrier tape to keep the aluminum spacer bars from contacting the metal roof, but I'm having a hard time finding any. They have some heavy duty rubberized tape which they said would work in a...

Couple more quick questions if you don't mind. Since all this tubing will serve as is a shim, I would think 1/8" thickness would be fine, correct? From what I can gather, it looks like 6061 series aluminum would work just fine, but since it will only serve as a shim, wouldn't 6063 series be...

Thanks very much!

Thanks. I finally talked with Renogy today, and asked them how much higher I should space the panels to address any possible heat issues. The answer was, 1.5 to 2 inches. Can anyone recommend some type of shim material in that thickness range that would be weather proof and heat resistant?

I did some time in Florida years ago, picking up produce. I feel your pain. So you are not seeing any loss of output from the heat? Part of mine just barely clear the ridges, and part of them are touching, so I'm almost certainly going to have to install some sort of shims between the roof and...

Eastern North Carolina. High of 81 here today. Hottest I've seen it here so far this year is 96.
