§ How to estimate, appreciate the meaning of the indicator value as to the hours of sunshine quantity per year?

At present, in Germany, the time when the sun is shining is recorded in minutes of the beam solar radiation (clear sky, allowing sunlight in the place of measurements) over a certain period of time in a certain place. The solar radiation duration is affected by the climatic zone, cloudiness, smog availability, terrain, season, and other factors. On average, from 1,300 to 1,900 hours of sunshine are registered in the country per year, with the average figure thus being equal to 1,600 hours per year.

To calculate the number of full sunny days per year, we divide the quantity of sunshine hours by 12, and to get the average quantity of sunshine hours per day, we divide it by 365. Of course, the figures obtained are averaged and do not provide accurate data regarding the actual number of sunny days per year.
