This study seeks to determine the effects of partial shading on the power output of solar panels and to test the effectiveness of bypass diodes in minimizing these effects. The first part of the study focuses on determining the effect of partial shade on the energy output of a solar panel. The second part of this study is aimed at establishing the effect that partial shade has on solar panel power output. In this study, partial shade was found to reduce the amount of energy generated by solar panels when compared to the solar panel in fully exposed conditions. After conducting experiments and reviewing scholarly works, this study concludes that partial shading does decrease the power produced by the solar panels, thus reducing the amounts of energy produced. Moreover, this research establishes that bypass devices are effective in mitigating these effects, which can improve the performance of the solar panel arrays, increasing the overall efficiency of solar panel systems. This research may offer support for the creation of new solar panel technologies that are more effective and efficient and can better endure the effects of partial shading, ultimately resulting in a global adoption of solar energy as a workable and sustainable energy source.
