How much solar energy is used for 220 volts?

Answer 1

"220 volts" is not a quantity of energy. You can have a hundred 220-volt outlets
sitting there in the walls of your house all day, and never use any energy. You only
use energy when something is plugged into that outlet, turned on, and draws current
from the outlet.

If you have some sort of device connected to a 220-volt source, and your device
is turned on and drawing 1 Ampere of current, then it's using 220 joules of energy
every second. It makes no difference whether those joules of energy come from
solar cells on the roof, from the electric company burning coal, from a different
electrical company that operates a nuclear station, or from an electric generator
coupled to your hamster's treadmill.
