Maybe you can help me out Mike. I have a 'logic gap' in my understanding of these solar systems.

Assuming you don't have all the expensive batteries storage systems, then I'm told these solar systems won't cover you during a power outage. To me that means the solar power is only pumped back into the grid. And then you get credited at a certain rate (let's say 10c and kWh). The power you actually use is, as usual, charged at, say, 25c a kWh. (So you'd need to product 2.5 times what you use per day to get a zero usage bill. But that's not my question).

My question is, if there. Is no direct application of the solar power into your home, then why do they say it makes sense to run things during the day? Surely it is just a mathematical calculation over the course of the day? Total power generated minus total power used = total billed.
