Forget the solar panel, just plug a big battery pack in an outlet of the wall, even a trickle charger and a truck battery would work. Then just use an inverter to convert to 110V.
If you have a balcony or can run an extension cord out of the window you can get a small gas generator and a couple 100 foot extension cords and run it that way. Here at the farm I put the generator in the bed of my truck, drive it to the back of the property and run long extension cords to the house. Keeps the fumes and noise a distance away. I run the cord in through the garage, close the garage door on it, then in a door closed as tight as I can on the cord. Then I run power strips and more extension cords to all the fridges, freezers, and a laptop for watching movies LOL. Usually once I get it all set up the power usually comes back on!!
