KZ Classic - solar roof weight?

My '13 KZ Classic 200 has a one piece aluminum roof, which according to Kz does not have traditional "rafters" ... there are braces up there for the AC and the antenna and maybe one in the back, and that's it AFAIK. It's a "non walkable" roof.

I'm thinking I would like to add some solar next year, around tax refund time, but I'm concerned about putting a 30-50 lb panel or two on a roof with no rafters.

Any Classic owners out there with solar on the roof ... how did you accomplish it?

    Another option to find the studs would be to remove an interior light, enlarge the hole slightly (as large as the installed light covers), and probe from there. I wouldn't have thought of it before having to pull out wet insulation after a small leak :(


    When I pulled out my factory speakers, I did some probing and found all sorts of weird shaped pieces of wood in that area... like KZ just stapled together scraps to support the AC unit.

    I was happy to find quite a bit of fiberglass insulation.

  • Looks like they went with too much is better than not enough on the sealant :)

    Your roof looks nice and flat, mine is wavy in every direction... maybe some heavy solar panels will help flatten it out.

    I'll dig out my ladder and probe my roof with the stud finder.
  • I have a relatively small 18 watt panel on my KZ Sportsmen 14RB. I had the RV place do the install as a part of the initial sale. As far as I can tell, it's held by screws, but actually secured by the adhesive underneath. I can't really tell if it's dicor underneath in addition to on top of the screws or what, but when I went to confirm the seals around everything, I couldn't pull the panel up easily. If I were to do it over again, I'd try a metal/plastic epoxy to hold brackets that would hold the panel. You're correct that it would NOT be best to walk on the roof. The 2x2 bracing underneath the roof isn't much.

    Here's a link to a pic if that's helpful.
