Solar doesn't replace base line generation unless you can get the power where its needed and as you are not generating power from panels over the majority of a day it means you must get it from someone who is generating it
Or generate and store excess energy during the day. I think the current challenge is that current energy storage solutions do not scale to the size of power plants?
Even the day storing may not be option, my home town chennai got a record rain in last one month with almost no sun for most of the days. Also the only thing that helped people are fossil fuel which is Candle and LPG stoves. The regular coal based thermal power was not there due to shutdown of plant as well as tranmission lines. LPG stove made people stay on first and second floor for two weeks with no need to come down.
I know I sound sarcastic but Tony Seba might find a solution by the year 2030: how to store energy to cover the needs of a city like New York(a city that never sleeps). He has been right on the spot regarding his previous predictions, right?
