Sonnenstrahlung, or solar radiation, refers to the energy emitted by the Sun in the form of electromagnetic waves. This energy travels through space and reaches the Earth, where it is essential for various processes, including photosynthesis in plants and the regulation of climate. The intensity and quality of Sonnenstrahlung can vary based on factors such as the time of day, season, and atmospheric conditions. Understanding solar radiation is crucial for fields like meteorology, climatology, and renewable energy, particularly in the development of solar panels that convert sunlight into electricity.
