Solar irradiance is the power per unit area received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument.

Irradiance may be measured in space, or at the Earth's surface after atmospheric absorption and scattering.

Solar irradiance is measured perpendicular to the incoming sunlight.

Total solar irradiance (TSI), is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere.

The solar constant is a conventional measure of mean TSI at a distance of one astronomical Unit (AU).

Irradiance on Earth is also measured perpendicular to the incoming sunlight.

Insolation is the power received on Earth per unit area on a horizontal surface. It depends on the height of the Sun above the horizon.
