Getting into solar panels.

Our first solar panel was an Ecoflow, Gen 2, bifacial, folding 110w and it’s excellent, it can produce much more than it’s rated to. Recently, In perfect conditions it managed 155w
I’ve now decided that I’d like to add x2 200w or maybe x4 200w rigid solar panels on to the roof of the Art Shack for a more productive setup.
My question is, if we are using the Ecoflow in the living room at the front of the house, but the solar panels have to be in the back garden about 25m away, how do you route the cables without your house ending up looking like the cabling in the Old Mir Space station and how long is a feasible cable length before you start to lose power because of cable length?
