solar radiation
The electromagnetic radiation that comes from the sun and reaches the Earth's surface or another body. Its intensity depends on factors such as time of day, season, and geographical latitude.
Starke Sonneneinstrahlung am Mittag kann die Haut schädigen.
Strong solar radiation at midday can damage the skin.
The word is made up of 'Sonne' (sun), the linking element '-n-', and 'Einstrahlung' (radiation / irradiation). 'Einstrahlung' itself comes from the verb 'einstrahlen' (to shine/radiate into). So it literally describes the radiation that reaches something from the sun.
Die Messstation misst die tägliche Sonneneinstrahlung.
The measuring station measures the daily solar radiation.
'Sonneneinstrahlung' (solar radiation) is often combined with adjectives like 'stark' (strong), 'intensiv' (intense), 'direkt' (direct), or 'gering' (low). A typical verb phrase is 'sich vor der Sonneneinstrahlung schützen' (to protect oneself from solar radiation).
Man sollte sich mit Sonnencreme vor der intensiven Sonneneinstrahlung schützen.
You should protect yourself from the intense solar radiation with sunscreen.
This word belongs more to written language or technical language. It is often found in weather reports, scientific texts, or health warnings.

'Sonnenschein' and 'Sonneneinstrahlung' both have to do with light from the sun. 'Sonnenschein' is the normal everyday word when you mean bright, pleasant sunlight. It is often used when talking about the weather or a beautiful day. 'Sonneneinstrahlung' sounds more technical and precise. It refers to the sun's radiation and often to its intensity, for example in connection with skin protection, plants, windows, or technology. Learners may confuse the words because both refer to sunlight. In everyday language, 'Sonnenschein' sounds more natural; when talking about measurement, effects, or danger, 'Sonneneinstrahlung' is more appropriate.

Because of the strong solar radiation, the child is wearing a hat.
