Filling void in van roof!

Hi,

What is the easiest way to fill the channels in the roof of my campervan (before adding a solar panel).  The attached picture shows the size of the channels.  Could I just make a lightweight filler with glass bubbles and fill the entire void?

My assumption is that the roof is GRP sprayed with car spray.  There is a fair amount of flex/twist as the roof goes up and down, although I'd say that is fairly minimal along the ridges themselves.

Many thanks

Why do you want to fill them ???
Most panels come with the corner mounts which can be fitted direct to the grp

I'm bonding a flexible solar panel directly to the roof.  Corner mounts are used with rigid solar panels.  I'd like to rephrase my earlier question... What proportions of epoxy/glass bubbles/silica should I use for a minimum density workable filler and what volume will I get per kg of epoxy?  Thanks
