Enhancing PV Power Extraction Under Partial Shading Condition with Shade Dispersion Strategy

Mar 1, 2024

Journal: Diyala Journal of Engineering Sciences 17 (1)

DOI: DOI: https://doi.org/10.24237/djes.2024.17104

Improving photovoltaic (PV) system efficiency is a popular field of research. Partial shading (PS) adversely impacts the solar system's output power, which considerably reduces the system's efficiency. As a result, this issue has been the subject of extensive investigation. When sunlight is blocked off of photovoltaic cells in a PV array, panel, or module, it is referred to as shading. Using a met...

Optimal PV array configurations for partial shading conditions

Oct 1, 2023

Journal: Indonesian Journal of Electrical Engineering and Computer Science 32 (1)

DOI: DOI: 10.11591/ijeecs

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. A novel approach dubbed a modified seriesparallel (MSP) setup, was suggested...
