Modeling of solar systems for estimating Received Solar Radiation

Today, one of the cases which are presented in the scientific world is energy and environmental crisis. Hence, one of the ways of dealing with this crisis is renewable energy system design. This study with help of Atmospheric Sciences Research Center of NASA, in the period of 22 years tries to estimate the solar radiation which many experimental techniques using meteorological, astronomical and geographical parameters are provided for estimation it. One of the issues that are important for optimal use of solar panels is making the angle in which absorbs the maximum radiation from the sun. In this paper, we try to calculate the amount of radiation to different angles panels over the years, and plot graphs of radiation in analytical software MATLAB, then estimate optimal slope, and provide charts to estimate. The results show that most of the radiation is related to the Jun and July, and the angle which leads to receive maximum radiation from the sun during the year is about 30 degrees. Also, according to the results of this study, the approximate normality of the data for prediction of radiation confirms the model presented and it is estimated as a proper model in the initial assessments, and accordingly, the estimation of radiation diagrams for the preliminary studies is evaluated properly.
