Potentiometric Analysis of Solar Energy in Rural Areas (Case Study: Sabzevar city)

Abstract

Excessive use of fossil fuels threatens the living environment on the planet by contaminating the environment, and today one of the solutions proposed for energy is the use of renewable energy along with the reform of consumption. solar radiation zoning map of the city of Sabzevar was produced 159 active village. and then the annual radiation pattern received in 2017 by radiation analysis and using DEM of the area with power The spatial resolution of 30 m was estimated for point-to-point radiation and finally, based on the village's demand and solar power production potential in the potential region. In order to better evaluate, the study area was studied in three parts of central Sabzevar, Roodab and Shastshmat. The central part of Sabzevar with the value of 90201150 and the sixth part with 66910770 watts per m2 have the highest and lowest total radiation, respectively. In order to determine the most important factor affecting irradiation, the correlation between the two factors of height and sunshine with total radiation was calculated and the results indicate that the correlation between total radiation and the height factor is far more than sunshine hours. Finally, the total radiation potential at the study area was calculated and evaluated, the results show that the potential of solar energy is scattered in rural areas with a low population density. The results also show that 95.82 percent of the city's surface has a high potential, 4.01 percent has a very good potential and 0.15 percent has a good potential.
