Determination of the optimum tilt angle for photovoltaic modules in Senegal

This paper deals with finding the optimum tilt angle of solar panels for energy applications. The objective is to maximize output electrical photovoltaic (PV) modules. A mathematical model was used determine collectors in Senegal on a daily and monthly basis, as well specific period. Then, configuration analyzed by studying four cases different typical climatic zones Senegal. On horizontal plane, sun spends more time south than north. means that Senegal, often set equal latitude. other hand, latitude only annual optimization. study shows does not produce maximum output. For angle, month November gives angles It preferable change conversion systems instead fixing them, gain energy.   Keys words: Solar energy, panels, orientation panel, latitude, geometry.
