摘要:
A method of providing a one layer solar radiation model for calculation of insolation includes: calculating direct solar radiation at a selected position, based on extraterrestrial radiation, eccentricity of the earth from the sun, and transmittance of gases in the atmosphere; calculating final diffuse solar radiation at the selected position, by using diffuse solar radiation due to air molecules, diffuse solar radiation due to aerosol, and multi-diffuse solar radiation with the atmosphere and the surface of the earth; accumulating the calculated direct solar radiation and final diffuse solar radiation for a predetermined wavelength region; calculating the direct solar radiation reaching the surface of the earth and the final diffuse solar radiation reaching the surface of the earth by applying the amount of cloud; and calculating global solar radiation at the selected positions.

Provided are a method and an apparatus of forming a solar radiation model applying topographical effects, the method comprising: calculating a slope angle and a slope aspect of a selected point on a digital elevation model data; calculating a final direct solar radiation of the selected point; calculating a final diffuse solar radiation of the selected point using the slope angle of the selected point, a sky-view factor of the selected point, and a diffuse solar radiation on the horizontal surface of the selected point; and calculating a global solar radiation using the final direct solar radiation and the final diffuse solar radiation.
