One of the pathways to achieving comprehensive economic and social development in today’s world is the existence of a reliable, continuous, and sustainable energy production source, such as renewable energy. Among the various types of renewable energy, solar energy has gained particular attention due to its ability to be directly converted into electricity and heat, its storage potential, and its infinite nature. From an economic efficiency perspective, this energy holds a significant position. Many regions in Iran possess the potential to harness solar energy and produce clean energy. Considering that the location of a solar power plant significantly affects its production and efficiency, determining suitable areas for its construction is of particular importance. In this study, the potential of Qazvin province for the construction of solar power plants has been assessed. ARCGIS software was used for this purpose. Initially, a potential assessment was conducted for the entire province of Qazvin, and based on international figures, the province was divided into three distinct regions, with low-potential areas excluded. Subsequently, the average solar potential for the remaining regions was calculated. In the final section, the use of parabolic solar collectors for harnessing the province's solar energy was proposed.
