I mounted 4 ICP brand solar panels
using the brackets included and hose clamping the brackets to the 1" ss tube frame. Not an elegant solution and I like the ones I read above. You can just make out the clamps in the left picture below. Two more panels were added later to an extension of the frome continuing over the cockpit
The hose clamps held the panels in place for a 1000 mile trip from Charleston, SC to Norfolk, VA and back on the ICW
including 55kt winds on Mothers day 2008 in beaufort
, NC. Also held for a 1500 mile trip from Charleston to Abacos Bahamas
including being hit by 2 10' breaking seas broadside and the array taking the brunt of the hit.
