| Abstract | ||||
| Solar radiation data are not easily available in many places over the world. Measurements of solar radiation in Mansoura either on a horizontal or tilted surfaces are too sparse to meet demand for scientific research and applications in agriculture and engineering. Estimation of daily global solar radiation is essential in Delta zone, since it is one of the most crowded areas and most agriculture and industrial activities are concentrated at this area where no solar observatory exist. Therefore, in this work, the hourly average total solar radiation data on horizontal, tilted (30° facing south) and normal surfaces is measured and compared with that data computed the clear sky model and the data recorded from the National Aeronautics and Space Administration (NASA) website [1]. Based on the MATrix LABoratory (MATLAB), a computer program has been developed to solve the clear sky model governing equations. The obtained results revealed that, the predicted solar radiation on horizontal, tilted, and normal surfaces were validated well with that measured. Results which are given in graphical form show that the data obtained from the clear sky model and that obtained from NASA website can be used as a reasonable and quick method for estimating the solar radiation when actual measurements are not available. | ||||
