Sun hours in Korbach
How sunny is Korbach? Over a year the sun delivers 1,250 kilowatt-hours onto every square metre here — in June roughly 6 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 3.43 peak sun hours per day in Korbach. In 9 out of 10 years at least 1,170 kWh/m² are reached. All values are computed from this location’s satellite hourly data, not estimated.

Daily average per month in kWh/m² at 35° tilt, south-facing, including the terrain horizon of Korbach. P90 = reached in 9 out of 10 years.
Optimal tilt angle in Korbach
The annual optimum for Korbach is 35° south; anything between 23° and 50° counts as equivalent (below 2% difference). For winter operation (off-grid) 65° is optimal, for summer use 20°. Flat-laid modules lose 13.9 % versus the optimum. Adjusting twice a year would add 2.4 % here, monthly adjustment 3.2 % — only relevant for adjustable mounts.
Is a balcony solar kit worth it in Korbach?
A vertical south-facing railing in Korbach harvests 885 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 106 % of the 35° December value, computed from the same hourly data with its own plane transposition.
