Investigation of effects of shading in crystalline silicon photovoltaic modules
Abstract
In this study, the effects of shading on the performance of solar PV modules was investigated using IV curve measurement technique. The PV module was subjected to different shading patterns using cardboards and the corresponding IV and PV curves obtained using the IV curve tracer. Results showed that shading reduces the power output of the module and that the reduction in power output not only depends on the number of solar cells shaded but also on the position of the shaded solar cells on the module.
