Analysis of Partial shading Effect on Solar Panel Power Output

Abstract

Enlarging solar power plants are increasing. This increase is to reduce compatibility with the use of fossil fuel electricity. Utilization of solar power plants is mostly used for street lighting and home industries. Solar power plants must rely on solar irradiation received on solar panels. The output power is also changed by large values from external factors such as partial shading. Partial shading is a condition that is closed / blocked by some cells in the solar panel. The application of partial shading is mostly only used with simulation software. However, in this final project research is carried out the implementation of partial shading and analysis to determine the effect on the output power that occurs in solar panels in actual environmental conditions. The application is made to know the output power during normal and partial shading conditions and to know the partial effect on the solar panel output power. The maximum value of the power produced in solar panels is 298.50 W. The maximum power value that can be obtained when a partial shade occurs is 141.13 W and the partial shade that occurs in the solar panel causes the power to increase under normal conditions.

Analysis of Global and Local Maximum Power Points in Pv Arrays Under Partial Shading Condition

“…Hence, rewriting (18) in the form of (7), and then by summing ( 17) and ( 18) for identical PV modules, the I-V characteristic for each increase of the i th row is determined by the equation:…”

“…The PS condition occurs when the solar panel cannot fully receive sunlight irradiation due to the partial covering of its surface by the shadow of objects such as buildings, trees, as well as the clouds. PS condition causes a drastic decrease in the output power of the solar panel system, thereby reducing efficiency and changing the maximum power point tracking (MPPT) algorithm [16]- [18].…”

Electric power from shadows and indoors: solar cells under diffuse light conditions

“…However, some critically affect the power generation or maintenance of solar panels. 2,[5][6][7][8][9][10][11][12] One of the aforementioned events is light diffusion, which includes scattering and reection of light. [13][14][15][16][17][18] In some cases, researchers have been so captivated by the concept of efficiency under the STC that they have neglected the variety of possible light conditions where photovoltaics are deployed.…”

Experimental study on impact of high voltage power transmission lines on silicon photovoltaics using artificial neural network

“…The study concluded that solar irregularities caused by climate change can affect the efficiency of PV modules and temperature changes due to solar irradiation have a great impact on degradation of solar cell (Magare et al, 2022). Later, some authors (Das, 2019;Giyantara et al, 2021;Ekinci et al, 2022;Vengatesh Ramamurthi and Rajan Samuel Nadar, 2022) have focused primarily on environmental aspects, such as the effect of partial shading, rusting, angle of incidence for PV modules and dust on panels, yielding various conclusions/theories. Furthermore, the performance of solar cells may also be impacted by magnetic fields surrounding the solar panels.…”
