I have been asked to attach a small solar charger panel for trickle
charger (maybe 6 inch square) thingy to a garage roof which has concrete

I wont see the job until Saturday so cant be 100% sure about anything.
Whats the best way to attach it, I first thought silicone but I doubt
that would adhere to the tiles, Then I am thinking just slip the bracket
(presumably it has one) under a tile.

Any other thoughts? Could I drill into the tiles and use a small screw?
Stainless steel " meccano" strip bent into a asymmetric U shape. feed
the ends above and below a particular tile and attach the ends to the
battens from the inside making small slots in the felt if fitted.

I got my strips from Navitron and used them to fit a solar thermal array
last year

They look very flimsy, has the panel been through a storm yet?

I used 9 of them - and had no problems. we live opposite a open space at
the top of a hill and the wind rattles the concrete tiles regularly in
the winter and the panel (30 tubes) about 2.4 sq m has stayed put.

Maybe you are thinking of the PV panel type mountings which are
considerably thicker and made from aluminium?
