It takes hours to days to start, stop, or change nuclear and coal generation rates. You can't just turn it on and off as needed. If you need coal or nuclear to meet overnight demand, you have to leave it running during the day as well. If you need 2MW of power overnight and 5MW during the day, you can only add 3MW of solar generation before you are putting too much power on the grid. If your solar puts out 5MW, you have to find out something to do with the extra 2MW that your nuclear plant needs to output continuously.
If you size your solar plants to produce 3MW in the middle of winter, then in summer they are putting out about 9MW. What can you do with the 6MW excess?
There is no single solution to manage every issue, but the single most important is "demand shaping". We need to reduce demands that can only be met with baseload generation. We need to move that demand to peak solar production times. We need to increase daytime demand to incentivize greater investment into solar. We need east/west transmission lines across every continent, shifting power from wherever the sun is up to wherever the sun is down.
Storage has to be a very distant second. Every 1 MW we time shift from night to day takes 2MW of load off the grid.
