Pete7, your set-up looks like a good way to keep the panel out of the way but secure.
We have decided against the single pole mount system - mainly because of concerns about it's security
with the weight of larger panels, but also price
(approx $1000 Cdn x2), and decided a larger frame also gives us some additional tie-on storage
We also took a hard look at our needs, and decided we're willing to forego constant refrigeration
if necessary, so that allows us to reduce our panel requirements to 170 watt x2. We live off grid now and are used to warm beer!
We're working with a local welder to make our own stainless frame. We've designed it with 4 legs, 2 securing to the deck
and 2 angles slightly aft, securing to the stern toerail and some with braces to the pushpit. If the cost isn't prohibitive, we'll include a lever system to adjust the panels' angle. We're just finalizing design and getting a quote.
Thanks, all, for your input.
