Welcome to EM!
I was reading your "Plugging into the Sun" blog and you were asking for suggestions on attaching the 2.4" square solar panels. Assuming the Insight isn't using aluminum body panels and magnets don't interfere with solar panel electricity, you can use the flat magnet sheets/tape that people use to make business cards and stuff :
15 mil - 10 pack of Self-Adhesive Business Card Magnets

I think I got mine at Staples or Michael's or a similar joint.
If you are worried about it flying off, have a neodymium magnet attached to the leading edge of the solar panel. The rest of the flat sheet magnet will have to be cut flush to this magnet and have the same thickness. Here are examples of the magnets I would use :
1/4" x 1/2" x 1/16" Thick NdFeB Plate Magnet, Ni-Cu-Ni plated.

I am using the magnet business card sheets to hold some airtabs on my car (
