The article considers the problem of an influence of partial shading on the characteristics of photovoltaic modules (PV modules). Different manners of connections of silicon solar cells contained in such modules are considered, e.g., classical PV modules (I and II generation of modules) and modules made using half-cut technology (III generation of
The impact of shading on the exploitation of photovoltaic
Of course, partial shading is not as bad as the shading of the whole cell of the photovoltaic module, leading to a total decrease of generated power by the installation up to 25%. However, far worse situation can occur if distinct part of the entire module is either partially or completely shaded.

Mathematical Analysis of Solar Photovoltaic Array Configurations
Solar-oriented PV cells can straightforwardly convert the sun powered capacity into the electrical power and be associated through various interconnections of cells to achieve more power. The sun-based PV panel or module is shaped by arranging PV cells in series, while the PV array is framed by the series and parallel association of PV panels.
Shading
Shading is a problem in PV modules since shading just one cell in the module can reduce the power output to zero. Shading one cell reduces the output of the whole string of cells or
