In reply to alex:
I've used 2 110W flexible panels. Firstly some cheap chinese ones that failed and now some German ones.
Rigid are much cheaper and about 30% more efficient as they can cool much better.
Flexible are mainly only beneficial for cosmetic purposes and perhaps if using roof bars etc...
If using flexible first mount a Dibond panel as it'll give a flat mounting surface and will help prevent work hardening of contact's within the panel, it'll also make removing the panel easier of it ever fails.
220W of flexible 22V panels, 2 6V traction batteries wired in series and a Ctek d250s with a smart pass keeps us off grid. But we only run a compressor fridge. (Dometic CRX50) lights, chargers and a 150W inverter for charging laptop and a speaker.
This it what we used https://sunworks.co.uk/product/semi-flexible-solar-panel-110-watts/ the brand is Wattstunde.
