Abstract
The human need to energy is increasing constantly and fossil energy sources is decreasing. The indiscriminate use of fossil fuels pollute the environment and threaten life on Earth. Today in addition to modifying consumption, use of renewable energy is one of the ways to solve the energy crisis. The Solar energy is one of the renewable energies. In this study the application of GIS in the Assessment of using solar energy to supply lighting systems of Highway Zanjan - Tabriz by function of Solar Analyst has been studied. In this article, the DEM ASTER satellite’s data of the study area in the Arc GIS software were used to calculate the solar radiation reaching the Earth's surface for six months (May and October).The results of this investigation showed that the study area due to variation of topography has different surface radiation and confirmed the possibility of using solar photovoltaic systems to supply lighting systems of Highway Zanjan - Tabriz. In the matter of the most important factor which affects the received radiation to surface, function of Solar Analyst has the most correlation with the height and the lowest correlation with the slope aspect.
