What`s the optimum wind to solar ratio for Germany in order to generate equal ammounts of electricity on a weekly basis troughout the year? Let us see how thing turns out based on how wind and solar performed in 2017. The table below express wind and solar generation as a percentage releative to average weekly electricity generation (EWF = weekly energy factor).

A 75/25 ratio seems to be a good fit. This is also close to the current wind to solar ratio which is and have been around 70/30 for serval years. Under is a graphic representation on the wind and solar generation from 2011 to 2018.
