HOLY SHIT THE SUN DOESN'T SHINE AT NIGHT, WHY HAVEN'T WE THOUGHT OF THIS?
Peak load is during the day, so initially it's not really a problem. Going from a grid that's 0% solar to 10% solar is really easy. The solar is going to just displace peaker plants. You don't really have to worry about night.
Going from a grid that's 70% solar to 80% solar is way more expensive, because you're probably using all that power at night.
You don't go all in on solar, that's dumb and unnecessary. The wind blows when the sun doesn't shine. We have lots of historical data on how the two would perform and how long a lull would be when neither are performing. Pad that number, put in enough storage to cover that period, and there you go.
Getting to 95% solar/wind/storage is relatively easy. Nuclear does not help this mix. It just makes it more expensive.
