I had issues with side mounting, too; I use dacron line for lifelines
and don't really have a place for rails. I don't seem to have any great photos of my installation
, but I invented my own bracket and used PVC pipe and seine twine and other stuffs to make an installation
where it isn't a problem, and it's damn strong! Doing so, I was able to get two 130 SUN Electronics
panels (which I had thought wouldn't fit at all) on my boat. They are completely external and hinge up for when docked.
The SUN panels were $2/watt when I bought them. If you want more detailed photos, I can have my father take some.
Two panels that don't interfere with the deck
Sorry I don't have better photos on hand...
