Solar irradiance

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. Solar irradiance is measured in watts pe

A pyranometer, used to measure global irradiance
A pyrheliometer, mounted on a solar tracker, is used to measure Direct Normal Irradiance (or beam irradiance).
Sunlight carries radiant energy in the wavelengths of visible light. Radiant energy may be developed for solar power generation.
Earth's energy budget

Earth's energy budget is the balance between the energy that Earth receives from the Sun and the energy the Earth loses back into outer space. Smaller energy sources, such as Earth's internal heat, ar
Earth's energy budget (in W/m2) determines the climate. It is the balance of incoming and outgoing radiation and can be measured by satellites. The Earth's energy imbalance is the "net absorbed" energy amount.
The growth in Earth's energy imbalance from satellite and in situ measurements (2005–2019). A rate of +1.0 W/m2 summed over the planet's surface equates to a continuous heat uptake of about 500 terawatts (~0.3% of the incident solar radiation).
