The extragalactic background light (EBL) is the diffuse radiation from all stars and galaxies, a dim but pervasive glow that fills the universe.
direct) radiation through the atmosphere, DiffFrac is the fraction of diffuse radiation through the atmosphere, SOF is the sky obscuration factor of the canopy as a function of solar elevation zenith angle, and [[bar.

Modified Hottel's model [3, 5] has been used to calculate the beam radiation and Liu-Jordan's model [5] to calculate the diffuse radiation.
The proposed system offers significant improvements in solar cell efficiencies compared to existing battery chargers and record flat plate terrestrial solar cells that collect both the direct and diffuse radiation and are not mobile.
To estimate the effect of the directional dependence of the diffuse radiation we made a virtual experiment, assuming that at the constant value of the global irradiance on the horizontal plane a part of the diffuse radiation is transferred from the isotropic to the circumsolar form as follows:
Both direct and diffuse components of radiation are useful; the only distinction between the two being that diffuse radiation cannot be concentrated for use.
