PHOTOVOLTAIC PERFORMANCE UNDER REAL DESERT CONDITIONS NEAR CAIRO

A photovoltaic panel of polycrystalline silicon solar cells from Solar ex was installed with a tilt angle of 30 degrees. The temperatures of the centre and side of the panel were measured by two thermocouples, i n addition to the global radiation and ambient temperature measurement s. The measurements were analyzed to determine empirical models for th e temperature effect and the resultant power. It was found that there is a drop in the voltage and power of the photovoltaic panel at noon d uring the spring and summer seasons.
