“…The thriving of photovoltaic technology can be attributed to various factors, including its environmental friendliness, the abundance of solar radiation, and its simple installation method on residential rooftops [5]. The photovoltaic effect, which is the process of turning solar photons into electricity by using semiconductors like silicon, is the basis for solar panel technology [6]. The factors that affect the effectiveness and performance of Systems the most are temperature, solar irradiation, and partial shading (PS) [7,8].…”

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 method that involves spreading shade throughout the PV array is one of the suggested fixes for this issue. This study compares the performance of a shade dispersion method to different PV array configurations under different partial shading circumstances, and it looks at how effective it is in a 3x3 PV system. MATLAB/Simulink is used for the evaluation. To achieve this, shade dispersion-based TCT (SD-TCT) under various shading scenarios has been compared to the current standard designs, which include series-parallel (SP), Honey-Comb (HC), Bridge-Linked (BL), and Total Cross-Tied (TCT). Based on the global maximum power (GMPP), mismatch power losses, fill factor (FF), percentage power losses (PL %), and PV system efficiency, the efficacy of the shade dispersion technique was assessed. For every partial shading condition (PSC) that was studied, the SD-TCT configuration outperforms the other setups in terms of fill factor and power loss.

“…It has become necessary to start searching for alternative renewable energy sources to preserve the environment, ensure its sustainability, and meet the increasing demand for energy as a result of the increasing population density [2], [6]. The widespread availability of solar irradiation, the ease of rooftop installation, and photovoltaic (PV) technology's low environmental impact have contributed to its rising popularity in recent years [5], [7]- [9]. The process of generating energy by converting solar photons through semiconductors such as silicon is known as the PV effect, and this is the basis for the work of solar panels [7].…”

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 series-parallel (MSP) setup, was suggested in this paper and compares its performance to four PV configuration strategies: series-parallel (SP), total-cross-tied (TCT), bridge-linked (BL), and honey-comb (HC). A 3×3 solar array is used in five partial shading arrangements. MATLAB/Simulink simulates all shading conditions. This study indicated that MSP delivers high performance and is superior to all other configurations in terms of maximum power in even and uneven row-shaded cases. in the case of an even column shaded, the performance of (SP, BL, HC, and TCT) was equal in terms of the maximum power obtained, while MSP was the least in comparison. the performance of the TCT configuration was the best compared to the other configuration when shading the PV system vertically unevenly. Finally, for diagonal shading, TCT and MSP configurations work best. Shading loss, mismatch loss and fill factor (FF) results were also compared.
