The irradiance of the sun is primarily dependent on **the wavelength of the radiant energy it emits**. The sun emits energy across a range of wavelengths, with variations in intensity at different wavelengths, which impacts the solar irradiance measured at the Earth's surface. While other factors like sunspots and solar wind can influence solar phenomena, they do not directly define solar irradiance in a fundamental way.
