Sun hours in Biberach an der Riß
How sunny is Biberach an der Riß? Over a year the sun delivers 1,443 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 3.95 peak sun hours per day in Biberach an der Riß. In 9 out of 10 years at least 1,338 kWh/m² are reached. All values are computed from this location’s satellite hourly data, not estimated.

Optimal tilt angle in Biberach an der Riß
The annual optimum for Biberach an der Riß is 40° south; anything between 24° and 51° counts as equivalent (below 2% difference). For winter operation (off-grid) 65° is optimal, for summer use 20°. Flat-laid modules lose 15.9 % versus the optimum. Adjusting twice a year would add 2.8 % here, monthly adjustment 3.8 % — only relevant for adjustable mounts.
Is a balcony solar kit worth it in Biberach an der Riß?
A vertical south-facing railing in Biberach an der Riß harvests 1,020 kWh/m² per year — 71 % 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 115 % of the 35° December value, computed from the same hourly data with its own plane transposition.
