Inspection The Effect of Panel Height on The Efficiency of Solar System

Abstract

Increasing the operating temperatures cause some loss of efficiency in solar system, so, study the nature of transfer and dissipation of the solar panel heat and its impact on the amount of the panel's production of electrical power has become an important factor in determining the efficiency of the solar panel. To reduce the possibility of excessive heating of solar panel, especially its upper part, an air gap between the panel and the land surface at which the panel with a certain height must be allowed to allow heat dissipation. The aim of this study is to investigate the effect of the height of the solar panel on the base or land surface and the effect of the air gap size, which provides the best output power of the panel. The inspection was conducted experimentally on four different heights (10, 20, and 30 cm) in four different positions to investigate the effect of air gap on the efficiency of the solar system. The investigation was firstly conducted in case when the three panels at the same height from the hatching roof, secondly, in case when the height of the first panel stay without changing, while the other two panels are changed for 20 cm and 30 cm respectively. The results obtained indicate that the efficiency of the solar panel is inversely proportional to its temperature rising. So, it can be concluded that the greater the air gap lead to more heat dissipation which lead to a good enhancing in the output power of the panel.

Keywords: Solar panel, efficiency, panel height, temperature, air gap.
