And the other months it's a not-so-strong dip in production (Jan 16%, Feb 31%, Mar 57%, Apr 94%, Jun 100%, Jul 100%, Aug 87%, Sep 60%, Okt 41%, Nov 22%, Dec 13%).
This means (for germany) we have to install more than 170% PV and store 3 months worth of energy for half a year (or install 800% and don't store anything). It's just a very rough estimation, but it's clear that one can't compare the cost of 1kWh PV to 1kWh nuclear (at least if one doesn't live in the desert).
No one is suggesting PV alone. My understanding is that Germany already gets more power from wind. Wind still works at night and in the winter, right?
