Normal beam radiation is computed from the hemispherical and diffuse radiation using two different methods. The two methods are found to agree generally to within 7%. The results are presented as country-border-

Computation of diffuse solar radiationA technique for computing the spectral and angular (both the zenith and azimuthal) distribution of the solar energy reaching the surface of earth and any other plane in the atmosphere has been developed. Here the computer code LOWTRAN is used for getting the ...
It has also been observed that there is a significant effect of region on beam and diffuse radiation due to cloudiness/haziness factors as expected. Further the data of solar radiation obtained from the Department of Indian Meteorology, Pune, have been used to evaluate the monthly performance of...

weather and terrain conditions. 2. Model mechanism The model firstly calculates the hourly beam and diffuse radiation fluxes on ideal horizontal surfaces in clear sky, then calculates the radiation flux on actual rough surfaces in clear sky, and at last considers the effects of clouds. ...
Some drawbacks of adopting solar concentrators are that only direct sunlight can be used on the receiver effectively (thus losing energy from diffuse sunlight), and that both optical and resistive losses are more notable under concentration43. To obtain the optimal concentration at the receiver for ...

where Pb, Pd are the beam irradiance and the diffuse irradiance. In addition, Ssolar is the area of the solar panel, and ηsolar is the conversion efficiency of the solar cell. We assume the lift and gravity of the SUAV are in balance during the whole flight. According to this assumpti...
Solar radiation incident on the top of atmosphere can be treated as a traveling plane wave normal to the line between the centers of the Earth and the Sun. The solar radiation propagating through the atmosphere can be partitioned into direct and diffuse radiation. Direct radiation is sunlight th...
