Making room for the intermittent nature of solar imposes upon the grid a large cost for backup power, adding to the levelized cost of electricity, yet this cost is never ascribed to the cost of the solar panel. The more solar you have the more idle backup power you need.

In France 70% of their power came from nuclear and they added renewables, they then need to throttle the nuclear power plants which is not an easy task, and they then make less money and require tax funded bailouts.
