Sun hours in Landau in der Pfalz
How sunny is Landau in der Pfalz? Over a year the sun delivers 1,363 kilowatt-hours onto every square metre here — in June roughly 5 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 3.74 peak sun hours per day in Landau in der Pfalz. In 9 out of 10 years at least 1,266 kWh/m² are reached. All values are computed from this location’s satellite hourly data, not estimated.

Optimal tilt angle in Landau in der Pfalz
The annual optimum for Landau in der Pfalz is 35° south; anything between 24° and 50° counts as equivalent (below 2% difference). For winter operation (off-grid) 65° is optimal, for summer use 20°. Flat-laid modules lose 15.2 % versus the optimum. Adjusting twice a year would add 2.2 % here, monthly adjustment 2.9 % — only relevant for adjustable mounts.
Is a balcony solar kit worth it in Landau in der Pfalz?
A vertical south-facing railing in Landau in der Pfalz harvests 945 kWh/m² per year — 69 % 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 110 % of the 35° December value, computed from the same hourly data with its own plane transposition.
