Sun hours in Greifswald

How sunny is Greifswald? Over a year the sun delivers 1,286 kilowatt-hours onto every square metre here — in June roughly 7 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 3.52 peak sun hours per day in Greifswald. In 9 out of 10 years at least 1,208 kWh/m² are reached. All values are computed from this location’s satellite hourly data, not estimated.

Optimal tilt angle in Greifswald

The annual optimum for Greifswald is 40° south; anything between 27° and 53° counts as equivalent (below 2% difference). For winter operation (off-grid) 65° is optimal, for summer use 25°. Flat-laid modules lose 17.7 % versus the optimum. Adjusting twice a year would add 2.9 % here, monthly adjustment 3.8 % — only relevant for adjustable mounts.

Is a balcony solar kit worth it in Greifswald?

A vertical south-facing railing in Greifswald harvests 949 kWh/m² per year — 74 % 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 123 % of the 35° December value, computed from the same hourly data with its own plane transposition.
