Have a look at Sikaflex 252, I have just finished putting an aluminium traytop onto my steel tray chassis and I am very impressed.
There is some info on the sikaflex site for preparation etc.
BTW what happens if you ever want to remove the panel, you will destroy it in the process of "unsticking" it.

hi all
to remove any object or items stuck down with silastic or sikaflex
just fully extend a razor knife blade and slide it through between item/object and the surface its mounted to
i have successfully done this
roof and gutter silastic is also suitable for solar panel mounting
its as tough as
just clean the surface prior to adhesion with rag and generous amount of metho and allow to dry off before aplying silastic
cheers

Sikaflex 252 is top of the line structurally, but probably stronger than required.
I would use Sikaflex 11FC which needs less surface prep and is more flexable.

I'll second that the aluminum cladding on my camper is stuck to the steel frame with Sikaflex 11FC still holding after 12 years

You have a topaz and I assume that you are going to stick it to that. Then tow it off road?

Sikafex 11FC is great. Comes in black, white and concrete grey BUT dirt sticks to it like
S------ to a blanket and you will never get the dirt off. ( speaking from expereince here). You might get lots of advice on removing dirt but this does NOT work on sikafex.

I would use non acid cure silicone (ie Selleys seal and paint for example) as the acid will destroy the back of mirrors and might effect the solar panel.

It will be much easier to remove than Sikafex as well

It will also be much cheaper as sikafex 11FC is about $16.90 a tube and silicone is about $5.95 for the same amount.

Wash the surface with soad and water then allow to dry. Seal all around the edges and flush as that dirt will get under the panel and once it rains it will slowly leak out as you drive. This producing a dirty mud trail down the topax.
