Solar panels not dropping at desired tilt

Hello. I am new to the forum and look forward to learning from my time here. I usually have been able to work through problems I encounter with my models but this one has me stumped.

I am dropping solar panels on a 3D mesh with Skelion and with the tilt at 31 degrees, after dropping the panels end up vertical on my 3D model. It does not matter if I select tilt or relative tilt when placing the modules nor does it matter if I select drop “coplaner to the surface” or “drop without rotation”.

I have been able to perform this function on other models but for some reason not on this particular model.

Thank you for any guidance you can give me.
