| Abstract | ||
| Sun is the main source of energy in Universe, therefore it's necessary to study the solar radiation values and models which are important in a lot of solar radiation research field because of this energy is pollution free with environment. In this study we have been employed global solar radiation measurements on horizontal surface in Baghdad city in order to carry out mathematical models, the statistical tests show that proposed models presented a good predicting ability of global solar radiation in Baghdad city, concerning to the seventh models which depend on solar zenith angle shows acceptable prediction ability, finally concerning to the last model which depend on two important parameter (the day of the year and sunshine duration) presented a power full prediction ability for the values of global solar radiation for Baghdad city. This study showed that the predicated values were close to the real values of solar radiation measurements, which have correlation coefficient ranged between (84.6%) and (98.2%) for the models which represented by the equations (14) and (16) respectively | ||
