This is not how solar works. Solar helps reduce the demand from col and gas during the day only. Solar is not just on and off, it ramps up to its peak around noon before dropping back down. This also happens to be peak very closely with the peak energy demand times. A grid getting 10% of its energy from solar is very happy. Around 20% and it becomes very difficult to find enough power when there are regional storms dropping solar output Germany is around 20% solar right now. At around 30% your grid is running primarily on solar during the peak hours, this really is about the maximum you can practically get from solar and it even relies on fucking with the market and turning down base load power during peak usage times.

From time to time on bright days with low power usage (such as holidays) Germany's peak power is 50% solar.

There are no economical grid sized batteries that in the long run would be cheaper to use than just adding fossil fueled power plants.
