The Sun as a power source: Understanding Solar Radiation.
Solar irradiance refers to the power per unit area received from the Sun in the form of electromagnetic radiation in the Earth’s atmosphere or at the surface. Measured in watts per square meter (W/m²), solar irradiance is a critical concept in meteorology, climatology, solar energy, and environmental science fields. Understanding solar irradiance is essential for the design and efficiency of solar power systems, as well as for climate modeling and weather forecasting.
