Grid tied solar doesn't care if your home is empty while collecting sunlight. The grid will carry the power to areas of demand.
Yes, but the power company typically buys it from you at roughly half the price they sell it for, so a system that is offsetting power used on the premises is far more cost effective than one on an empty house.
There's also transmission losses to consider.
Put in a larger battery if you are interested in using site produced solar at unlit hours.
Those are expensive, and not particularly environmentally friendly either.
Less usually. Half the time it costs you to supply them with power. It's a rip off
Why do you think we step up the voltage as far as 220 thousand volts? You can lose a maximum of 5% of the nominal supply voltage between the switchboard and the load inside a building, and 7% from the point of supply to the load.
Transmission loss on low voltage is definitely not insignificant.
