I hear two arguments:

a) renewables provide the most power when power is used the most (during the day when the sun is shining to run a/c)

b) charging EVs at night will balance the grid

I don't think you can do B with A, right?

I never said A or B. My point is super straightforward, having solar is better for the grid than having no solar.

I never said that you said A or B.

Of course having something useful is better than not having it.

The issue is, that a lot of people seem to be interested in replacing more-useful things (nuclear which provides power during the day for a/c and power at night for EVs) with less-useful things (solar which only provides power during the day).
