Abstract
Generate real total radiation spatial distribution of solar radiation using cloud mask algorithm
Highlights
The main goal of this paper is to illustrate the opportunities the r.sun model provides for assessing the solar potential of a selected area under the real sky conditions
The raster map of the spatial distribution of the real total solar radiation is presented in the picture below (Fig. 2)
The r.sun model can be regarded as an efficient method of determining the spatial distribution of incoming solar radiation
Summary
The main goal of this paper is to illustrate the opportunities the r.sun model provides for assessing the solar potential of a selected area under the real sky conditions. As the clouds constitute a barrier for the radiation of the sun, the solar radiation models should include the cloud cover This problem has been examined in numerous studies, and some authors Miklánek, Suri, Hofierka [6, 13, 17, 16] used data from the local ground stations to determine the range of the clouds. Such data is reliable exclusively for a region surrounding the station. Such data includes the image of the cloud cover for the selected area and, most importantly, it shows the cloud cover over all the terrain
