How much electricity is saved when you use solar panels
project for school
So maybe you should actually get good information that is backed up, not random opinions.
none, you just don't use any electricity from the power company. you still use the same amount of electricity.
However much your solar panels generate, at the inverter output.
Depends on how many panels. Enough panels, and you can save it all, and store the overage in batteries for use during the night when demand is lower.
that's not the purpose of a solar panel hypothetically they preserve energy
