You could fairly easily run a completely seperate 12VDC system through your house, I've seen it done, chap ran thin flat black n red cables around his house on the surface of his walls, usually just atop of the skirting boards, he covered the cables with 3 inch masking tape and emulsioned it to match the walls. He fasten 12VDC fag lighter sockets in the places he wanted back to his Pv charged battery bank.

Remember i know nowt about lectric but I do remember him saying he put losts of inline fuses on each line to ensure nothing overheated or went bang.

all his goods came from E bay and the 12 volt shop
