Abstract
ABSTRACT The aim of paper includes evaluating the performance of a proposed design of a photovoltaic solar chimney. In this design, the solar cells are fixed in the mid-distance between the chimney base and the glass cover. Therefore, the air can move over and below the solar cells to accelerate the photovoltaic cells' cooling and obtain the air's high velocity. The results showed that the photovoltaic cell location determines its temperature, where high temperatures characterized the solar panels in the middle. The solar panels on the ends, on the other hand, were at a lower temperature. In addition, the temperature of the solar panels is affected by the weather. Due to the low temperatures of the solar cells throughout the monthly test, optimum efficiency values were observed in the early morning. Max -electrical efficiency value was 13.9 % for April. In contrast, min- electrical efficiency was 11.5% in August at 1 p.m. The highest recorded thermal efficiency values were 58.9% for August at 1 p.m.
