Peak sun hours a day on flat ground. Each dot is one place (the 900 largest).

The sunniest places in Germany, with 3.42 peak sun hours a day on flat ground, are Weil am Rhein and one other place; the least sunny are Berlin and 3 other places with 2.83. A 1 kWp array at its best angle makes from 1,027 kWh a year in Berlin to 1,252 kWh in Garmisch-Partenkirchen — 1,097 kWh on average.

The best year-round tilt runs from 38° in Munich to 41° in Flensburg. Off-grid systems are sized for the darkest month and do better steeper, at 72° on average: at 70° that month brings 0.83 kWh per kWp a day in Stralsund and 2.34 kWh in Garmisch-Partenkirchen.
