The location of PV modules on collector rows affects the modules output power - experimental verification
Abstract
In multiple collector rows of photovoltaic fields, the collectors may be installed with several modules placed one above the other along the collector width. The PV modules experience uneven incident diffuse radiation caused by differences in the modules' sky view factor. The present experimental study verifies the sky view factor model, and shows the differences in output power of the PV modules placed in different locations along the width of the second collector row. This work is a complementary experimental study to the theoretical previous work, and emphasizes the importance of the incident diffuse radiation, associated with the sky view factor, on the energy loss of the PV field. Two collector rows deployed with PV modules were tested on the laboratory roof for several days for different inclination angles and distances between collector rows. The results show that a top module may generate 8 percent more power than a bottom module at noon time. The findings of this experimental study have technical significance in designing PV systems.
