I didn't realize you were working with a flexible panel. I had one that came with my boat that was used. It was pretty old and it seemed to have a short in it & sometimes wouldn't charge properly when it became hot in the sun.
I went with a solid panel because of cost and output. The panel is about 14"x20". The other advantage here in Texas is cooling. The solid panels tend to cool better because of air flow. You will need to mount some spacers to let air flow under the panel if you are in a hot area.
Let me know if you want one.
Not sure the price of your flexi panel but this would run about 195.00 like you see.
I would like to see a picture of the mount on Ainia if possible.
Mdbee, how did you assemble that?
Mine is a bit different as I have a flexible panel which is only about 1/8" thick. There is a grommeted hole at each corner for mounting, I am just figuring out what to mount it to, and how to attach it to the boat.
