Sun hours in Ehingen an der Donau
How sunny is Ehingen an der Donau? Over a year the sun delivers 1,418 kilowatt-hours onto every square metre here — in June roughly 4 times as much per day as in December. “Sun hours” has two meanings: the weather report counts how long the sun shines. For solar power what matters is how much energy arrives — and that is what this page shows, as peak sun hours (hours of full sun power).
For solar planning this means: an optimally tilted, south-facing array (35°) harvests an annual average of 3.89 peak sun hours per day in Ehingen an der Donau. In 9 out of 10 years at least 1,306 kWh/m² are reached. All values are computed from this location’s satellite hourly data, not estimated.

Optimal tilt angle in Ehingen an der Donau
The annual optimum for Ehingen an der Donau is 35° south; anything between 22° and 49° counts as equivalent (below 2% difference). For winter operation (off-grid) 65° is optimal, for summer use 20°. Flat-laid modules lose 13.7 % versus the optimum. Adjusting twice a year would add 3.1 % here, monthly adjustment 3.8 % — only relevant for adjustable mounts.
Is a balcony solar kit worth it in Ehingen an der Donau?
A vertical south-facing railing in Ehingen an der Donau harvests 991 kWh/m² per year — 70 % of what an optimally tilted 35° panel yields at the same spot. December softens the penalty: with the low winter sun, the vertical plane reaches 101 % of the 35° December value, computed from the same hourly data with its own plane transposition.
