Have been reading up on solar power .
There is a thing I do not understand .
1) I know for the grid tie-in to happen you need an inverter to change DC to AC and make sure you have the same 60Hz . Thing is I cannot understand how in electrical terms do you feed the power back ? From what I know power substations do not store electricity right ? So how is it exactly that the power get feed back to the grid ?
Thank you
