Abstract
One of the most important steps in using any renewable energy source is to accurately estimate it. Universal solar radiation is generally measured on a horizontal surface, while the maximum amount of solar radiation is a collision on a sloping surface. However, in order to take full advantage of solar radiation on collector surfaces, conventional fixed solar systems, both solar photovoltaic and flat panel solar collectors, are installed on sloping surfaces. In this study, the HDKR model has been used to estimate the radiant energy on the horizontal and sloping surfaces of solar collectors. In this regard, using MATLAB software, the amount of energy received by the solar collector throughout the year was investigated. The results of this study show that in the Ahvaz International Airport station, in terms of average monthly, the highest amount of direct radiation for clear skies is related to June with 206 kWh / m2 and the lowest amount of radiation for February is 113 kWh / m2. Square meters.
