I've got a home brewed system with a outboard
flip up panel on each side attached just forward of the stern. My super simple home made brake-clamp system with hardwood block brakes can hold them in any position without the need for a supporting strut, which makes setting them to any angle very quick and easy. They are subject to shade from the cockpit bimini
but when compared to the arch mounted panels
, they don't fare to badly in the power generation stakes. It's totally feasible to uses them when sailing on my setup, but this might necessarily apply to other setups.
The other thing I have that may be of interest for use solely at anchor
is a solar
blanket. Those things rock!
