Solar cells are photovoltaic devices that convert sun energy directly into the electrical energy. Solar panel is composed of multiple solar cells that are combined together. Depending on the power demand, solar panels are connected to each other in series or parallel. Thus, electrical energy from the solar array systems is created to meet the needs. Solar panels are used on roof and wall systems in buildings and power plants. In solar array design, radiance, temperature, shading, surface angle and effect of series-parallel connection, which are factors affecting the operation of solar panels, should be considered. Shading significantly reduces the efficiency of a solar array system. Shading can occur entirely or partially due to dynamic or static obstacles. The effect of shading varies by location at which the solar panel is formed. In this work, design and optimization of solar arrays, positioned over a large area, having different time constant shading effects, was performed in order to minimize shading effect.
