I have one of these : www.anacondastores.com/camping-hiking/power-cooling/solar/projecta-folding-solar-panel-kit/p/BP90039421
They come in 80 watt and 120 watt. Bought for same reason easy to handle, small storage footprint. Works well keeping 80 ah battery and 35 litre fridge going. On special paid $399 for 80watt panel. Looked at redarc blanket but seemed they were harder to prop up toward sun due to lighter build.
How is this for an idea
And all depending what you need ?
Maybe a 120 folding pannel ,
have them spit to a set of single pannels ( so they are not to heavy to lift ) only 6 kg each pannel than
and connect them with the right cabels to a decent regulator close to the house battery
The easiest way is to fit as much solar to the roof as you can afford and then forget it.
More capacity, no storage problem, no setting up, no getting pinched, no lifting and shifting.
