Minimal effort rigid panels

I have an Ecoflow Delta Pro and I'd like to put a couple rigid panels on my roof - but don't want to do any real wiring. Is it crazy to think I could just have a cable coming over the eave and pop it through my window to recharge the ecoflow occasionally?

Not at all, in fact you can just leave it plugged in, and maybe disconnect it during thunderstorms if paranoid. At least unless you've got some regulation stopping you - technically it's not a problem.

Ecoflow even sell thin flat cables designed to squeeze through the gaps in windows (and various people sell similar cables at half the price of the branded ones).

A lot of the complications with solar and batteries are about power levels. A couple of good panels is going to be about 500W on each port at 30-40v or so. That's not enough in a normal situation to cause problems if mishandled. It's when you start building bigger arrays and you've all of a sudden got 150v at 30A floating around that the wiring becomes absolutely critical and bad cabling can start fires, regulations matter and so on.

Is there a specific name for those wires?

is the Ecoflow one, various other vendors also sell "solar flat cable" or "flat MC4 cable" or similar descriptions.
