So you apply the vinyl onto the hood and then tape the solar panel to that? I'm surprised by how thick the panel is, a 1/2 inch? I have an Overland Solar panel taped to my glass roof on my LR3 with 3M vhb tape and it's only about 3-4 mm thick total.
Problem with the roof mount is when I put my roof rack on it's not charging due to all the stuff I carry on my rack so I'm looking to add the hood mount to get power no matter what. I only put my rack on when I do a big adventures which is a couple times per year, and the solar really matters in the winter when I'm not driving as much.
I've contacted Lensunsolar about their panel (thanks for that @
djkaosone), very similar to the Cascadia in size, but Lensunsolar was able to get more output due to the array layout and it's advertised as 2.5mm thick, also slightly lower cost.
