Abstract

The research highlights the importance of directing solar panels quarterly and within daylight hours within each single season - in achieving the highest solar gain that can be converted into electrical energy. The study included four seasons (summer, winter, and spring and autumn equinoxes). The standard score was applied as a statistical method to classify the difference in the energy reaching the surface of the solar cell panels. The specific angles of the location of the sun disk in Diwaniyah city were determined by its astronomical location using (Energy 3D program), and the intensity of direct and diffuse solar radiation was measured using a device ( Solar power meter (SPM-1116 SD) has been observed site monitoring The field of solar radiation away from buildings to avoid the impact on the radiation intensity of connecting.

      The study reached a set of results that can be summarized as follows

1-The highest energy gain is achieved when the solar cell panels are stationary towards the position of the sun disk specified at the head azimuth angle (zero⁰) in the summer at 830, and the highest energy gain is achieved when the solar cell panels are towards the sun disk position at the angle specified The azimuth of the head (zero⁰) at (1030), but at (1230) the highest energy gain is achieved when the solar cell panels are fixed towards the position of the sun disk specified at the angle of the head azimuth (zero⁰) (1230)

2-The highest energy gain is achieved when the solar cell panels are moving towards the sun disk specified at the angle of the head azimuth (⁰45), and the angle of the horizontal dimension (135⁰) southeast at 830 in winter, and at 1030 The highest energy gain is achieved when the solar cell panels are moving towards the sun's disc set at the angle of the head azimuth (⁰30), the angle of the horizontal dimension (180⁰) south, and at 1230 the highest energy gain is achieved when the solar cell panels are moving towards The sun disk is determined by the angle of the azimuth of the head (45⁰), and the angle of the horizontal dimension (180⁰) southward.

3-Autumnal equinox presided the rest of the seasons in the proportion of time, which sees a (very high) difference in energy in the case of the movement of solar cells coinciding with the movement of the solar disk compared to gain energy in the case of stability to reach (22.44%) within the time span of the hour ( The difference in power gain was (326.3 W / m2 / hour) and the horizontal dimension angles ranged from (112-129.08), while the percentage of time witnessed (very high) difference in Summer to reach (14.28%) rate of difference in energy gain of (273.9 W / m2 / hour) and angles of horizontal dimension ranged between (143.08 to 160.2 ⁰).
