mounting solar with screws.

Question

has anybody ever had to remove a solar panel? The ones I bought use 4 Z brackets. a bolt comes though bottom of solar frame, than through Z bracket. once z bracket is mounted to roof, the only way to get panel off is to cut the seal and unscrew the Z brackets from roof.
I can't drill hoes into side of panel for mounts as it will void warranty.

But besides a broken panel, why would I need to remove them?
I can use a chimney nut, that slides on panel frame and clips in hole, than put a bolt up though bottom of Z bracket into frame, but I fear that the hidden chimney nuts could rust out and give way with wind pressure when I am going down the road (I do camp in salt air a lot).
even with this chimney nut, I only have 5/8" inch between bottom of bracket and roof if I did need to remove the bolts.

I am over thinking this right? just bolt bracket to frame, test everything out, than screw and seal it down?

Than just keep the chunks of debris out from between the panel and roof (dead leaves, etc). When washing roof just get in as far as you can with a brush.

Yes. Broke panel.
But generally unless broke, need would be very rare. Roof replacement, or refitting another panel, changing layout? Cant see a reason.
Unless new replacement identical, unlikely, mounts probably need relocation anyway.
So I wouldn't make allowance they could be reused, mount like its going to be there forever...

A TC is probably the better place to use them since it's unlikely to tilt. I doubt very much that you will ever have a problem with the panel itself. More likely might be the connections on the rear of the panel. If the cover is removable or if you have to attach the wires to the panel box, be sure to use electrical grease in there. I would never put anything up there that isn't aluminum or stainless. There are better grades of stainless too.

With the low panel prices I would guess that it's going to be borderline worth while years from now to even use the warr when shipping prices keep going up and panel prices keep going down. I drilled holes in all my panels for rivenuts and tilting. If tilting is practical and you need the increased performance, tilting does help a good deal. I have never run into anyone who has replaced a panel and I often run into people with very old panels.

I used the same Z brackets and bolted them to the panels and screwed them to the roof. My only problem was that the wires were under the panel and me fingers would not reach them. A coat hanger get them out. Project done.
