Optimal PV array configurations for partial shading conditions

Indonesian Journal of Electrical Engineering and Computer Science, 2023
Increasing the effectiveness of photovoltaic (PV) power generation systems is a major barrier to their widespread use. Partial shading conditions (PSCs), which are caused by nearby objects like trees, buildings, and clouds, reduce the energy produced by PV systems and may be mitigated by the reconfiguration of PV arrays.

Performance Analysis of Partial Shading Effect on PV Plant

Journal of Engineering Technology and Applied Physics, 2023
Partial shading of PV plants mitigate the maximum power generation of solar modules. As a result, the power output is lower than expected. It is affected not only by the number of shaded modules but also by the shaded patterns.
