Characterization of photovoltaic solar Panel efficiency for requirements of urban planning at Al-Jadyria region

Abstract

Sunlight has influenced building design since the beginning of architectural history. Advanced solar architecture and urban planning methods were first employed by the Greeks and Chinese, who oriented their buildings toward the south to provide light and warmth. The performance of a solar cell under sun radiation is necessary to describe the electrical parameters of the cell. A Solar panel analyzer is used for the professional testing of four solar cells at Al-Jadyria climate conditions. Voltage -current characteristics of different area solar cells operated under solar irradiation for testing their quality and determining the optimal operational parameters for maximum electrical output were obtained. The results also showed that the new solar panels have the highest efficiency (made in Spain) (efficiency=14%) compared with the older ones (made in Iraq)(efficiency less than 7%).
