An estimation of solar radiation components on horizontal surfaces in Palestine
الخلاصة
For many developing countries solar radiation measurements are only available for selected stations
due to the cost of the measurement equipment and techniques involved. In this work a simple model
was developed to estimate the direct, diffuse, and total solar radiation on horizontal surfaces.
Calculations were made for solar solstices and equinox for the purpose of testing the model. Results
suggested that the model gives an acceptable estimate of the direct, diffuse, and total components of
solar radiation components. The model can be used for any location in the northern hemisphere.
