Performance evaluation of photovoltaic module at different tilt angle in kuwait

In this paper we will study the performance of a Silicon Photovoltaic (PV) with different tilt angle arrangement in State of Kuwait (latitude 30° N). In the study the PV system is installed facing South, collecting maximum solar radiation at noon, and their angles are from 0° to 90° respectively, during full year at the Solstice and Equinox periods, aiming for the best output power towards vertical (90°) panel. The results shows that both the final yields and performance ratio of the PV system with 50° tilt angle, the output power is higher in six months, equal in two months and lower less than 10% in six months to the latitude tilt angle (30°) during a full year.
