I have gradually increased my panel coverage and now have 720w of unshaded solar on the stern of my 28 foot semi liveaboard cruising trailer sailer.
Four thin frame hard panels three of which exactly fit over my dodger and one is tiltable mounted hanging off the rear of my targa bar.
I have a further 160w thin frame hard panel between the handrails over my cabin roof which is sail shaded but at anchor can tilt port or starboard by releasing one side.
Further to these hard panels I have a couple of semi flexibles one of which is mounted on my dodger but moves up on top of my bagged mainsail at anchor and another which mounts over my (bagged when sailing) central Bimini used at anchor to provide total cockpit cover.
Total available of just over 1000w on a trailerable mono hull yacht.
All the panels are easily removable to stow below on a berth with the hard panels being attached by plastic thumb screw type clamp mounts but to date have not found the need to do this despite some 35knot plus days.
They also remain in place whilst towing between cruising grounds withstanding both 50knots plus windspeeds and road shock from potholes.

The forward tension straps shown here have been replaced with stainless tubes running up to the leading edge of the structure giving much greater support and load sharing. The whole structure tilts forward to allow the mast to sit on top whilst towing.

Combined with two lithium power packs I now have 240v off grid power available whilst cruising and cook via induction, have a 240v 800w hot water service and both a fridge and separate freezer along with an electric dingy/auxiliary torqeedo outboard that these also charge along with a number of other occasional use 240v appliances.
Further to these a 12-24v vitron voltage increaser assists boosting charging to these at 350w when occasionally using my main outboard.
I have seen other with side rail swing out solar panels and various other solutions for panel mounting on smaller yachts.
