A typical resedential 110 is all that is required.

The Solar Panels are usually DC (Direct Current). 12 volts is a standard DC voltage.
Your home power is AC (Alternating Current).
To get AC from DC you need an inverter. But that would not be the best use of your efforts.
DC is used for many small instruments and you should look for 12 V DC heaters, lights, etc. to use with the energy from your solar panels.

There is nothing special about 48 volts. If you want 220 AC, you will need to shop for an inverter; investigate what supply voltages they like, and possibly rewire your panels to provide it. In general, solar panels are not economic for home use unless you can get a really fat subsidy for installing some.
