Sažetak
Energy consumption in buildings depends on the solar irradiation received on inclined surfaces (windows, walls, roofs) of different orientations. Due to the lack of the instrumental measurements of irradiation on inclined surfaces, the irradiation model based on total and diffuse irradiation on a horizontal surface is used to calculate the components on inclined surface. Total and diffuse hourly solar irradiation components are measured at two meteorological stations in Croatia, one inland (Zagreb) and other one on the coast (Split). Total irradiation on inclined surface is represented in a radiation model as a sum of direct, diffuse and reflected irradiation. Geometric model is used for direct component ; anisotropic model is used for diffuse component while for the calculation of the reflected irradiation the satellite derived albedo is acquired from EUMETSAT CM-SAF. In situ measured irradiation on a horizontal surface is compared and validated with the EUMETSAT CM-SAF SIS (global radiation) and SID (direct radiation) satellite observation products. The comparison is performed on a daily and monthly level. Based on comparison of the in situ and satellite observations, the products are considered to be prepared that can be used for different applications, e.g. for estimation of the solar potential for any location. Due to a fine resolution of the CM-SAF SIS and SID products of 0.03° or 0.05°, fine resolution of the analysis is possible. Given that CM-SAF products are providing homogenous sets of high-quality data they are adequate to investigate climate variability and long-term changes in the climate mean state also.
