1 The LCOE for PV is not the rate the POCO pays you when you sell during the day. They are unrelated.
2 You are right that if your daytime sell price is less than your nighttime buy price from the POCO, there may be a case for batteries economically.
3 However, with net metering is that this doesn't occur (assuming you are still a net consumer of electricity).
4 me-if the cost to you of energy you produce is less than the price you'd pay to get it back...why would you sell?
Because the price you get selling that energy is bigger than or equal to the price you'd pay to get it back?
If you're deciding whether to sell and buy back, your cost doesn't matter. Just the sales price and the buy price.
5 If you're deciding whether to sell and buy back, your cost doesn't matter. Just the sales price and the buy price.
We are *almost* on the same page, but more like on the same sheet of paper but opposite sides of that one sheet.
1 If the LCOE was more than the price you were getting for selling the energy it produced, there would be no reason to do it, so they are related. "How" is the question.
2 Thank you. We have agreed!
3 Whoops! Your "daytime sell price" isn't just how much the POCO pays you- it costs you the LCOE/kWh to produce it. Again, if that daytime sell price was LESS than the LCOE to produce it, there would be no reason. So with net metering, sure you are "buying and selling" at X cents, but it really costs you the LCOE for what you have sold. You'd be losing money on what you sell if you weren't generating extra during the day to cover the night. X doesn't change on the "buying" side- that's why you have to put out extra during the day to cover the night.
You aren't really "buying" anything at night, like you say, you're just using your "free battery"...that's why the correct cost for filling that battery is important.

5. I think what might be happening is we aren't defining who net metering and/or batteries are "good for", while trying to discuss both.
Let's focus here- do you agree with this: net metering is only good for the person/company not trying to "make money" directly from net metering, ie- a homeowner who wants no bill and a longer payback period OR a PPA company/developer/installer who is making their money off of something other than a zero bill?
