LCOE doesn’t include storage and transmission

So what?

My previous comment said:

As in: no storage or new transmission needed, put it right by the existing gas plant and wire it together, *burn less while the sun is shining*.

Batteries… well, I hope they keep getting cheaper, but IIRC them+PV currently beat nuclear. Not sure about other stuff though.

rooftop solar saves transmission cost and doesn't require storage.

Nothing “requires” storage, but if you want power at night or during a cloudy week you need it or you need dispatchable generation like gas or nuclear

right. the fun point were at is that solar+gas is cheaper than gas. it's worth buying solar panels just so you don't have to burn the extra gas

Thats what i would like to know lol

You already got the answer. This has been demonstrated. Yes, PV+gas is cheaper than gas.
