Solar spectral irradiance finds and shows the distribution of solar radiation over wavelengths. The measure of radiation, in the spectral distribution, is in terms of the amount of energy falling per second (W) per unit area (m 2) in each band of 1 µm wavelength.
Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m 2) in SI units.
The average annual solar radiation arriving at the top of the Earth's atmosphere is about 1361 W/m 2. This represents the power per unit area of solar irradiance across the spherical surface surrounding the Sun with a radius equal to the distance to the Earth (1 AU).
Irradiance is the power of solar radiation per unit of area, expressed as W/m2. Irradiation or solar energy is the solar power accumulated over time, expressed as J/m2 or Wh/m2. The higher the irradiance, the more energy is generated. In the PV industry setting, the term irradiation is not conventional.
Dahlioui et al. showed that solar radiation greatly affects the output power of PV modules, but airborne pollutant particles reduce their power generation efficiency by 15 %. Yue et al. found that suitable orientation of PV panels is beneficial to increasing the power generation of PV systems.
This represents the power per unit area of solar irradiance across the spherical surface surrounding the Sun with a radius equal to the distance to the Earth (1 AU). This means that the approximately circular disc of the Earth, as viewed from the Sun, receives a roughly stable 1361 W/m 2 at all times.
