The problem is not lack of grid capacity. California is capable of importing upwards of 11 GW[0] but there was only around 8 GW[1] available yesterday because it's hot in neighboring states like Oregon too.

The load shedding occurred around 8-10pm after the sun has gone down (but while it's still quite hot) so more solar wouldn't help much.
