Right now, the southern half of Germany has clear skies and thus a bright, sunny day approaching noon. These are optimal conditions for solar energy. This is why renewables get to approx. 40% of the energy mix right now. Let's have another look at those numbers around sunset (approx. 6 hours from now) and see where that goes.

"Utilizing 28.36% of installed capacity" is what the linked map says about solar right now.

I just rewound the slider to 8pm yesterday and it says "35% renewable".

I am not sure how much of these 28% are due to the distribution of solar panels in Germany and how much is due to seasonal effects. Solar irradiation varies a lot over the year. I vaguely remember that it goes down to about 300W/m^2 at noon in winter and peaks at around 1kW/m^2 at noon in summer, but I don't have time to verify that right now. The exact numbers vary by location, of course.

But I can confirm that the sun is shining because it's shining directly on my roof and satellite images show a clear sky for anything south of Frankfurt.
