Sun hours in Schwäbisch Gmünd
How sunny is Schwäbisch Gmünd? Over a year the sun delivers 1,357 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 3.72 peak sun hours per day in Schwäbisch Gmünd. In 9 out of 10 years at least 1,245 kWh/m² are reached. All values are computed from this location’s satellite hourly data, not estimated.

Optimal tilt angle in Schwäbisch Gmünd
The annual optimum for Schwäbisch Gmünd is 35° south; anything between 24° and 50° counts as equivalent (below 2% difference). For winter operation (off-grid) 60° is optimal, for summer use 20°. Flat-laid modules lose 15.4 % versus the optimum. Adjusting twice a year would add 2.6 % here, monthly adjustment 3.4 % — only relevant for adjustable mounts.
Is a balcony solar kit worth it in Schwäbisch Gmünd?
A vertical south-facing railing in Schwäbisch Gmünd harvests 953 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 107 % of the 35° December value, computed from the same hourly data with its own plane transposition.
