Abstract

The issue of electrical power losses in solar Photovoltaic modules during partial shade is discussed in this study. PV modules work more efficiently with maximum power if solar irradiation reaches the entire surface of the panel without any parts been shaded. A PV system modeling software package, PVLib, is used to calculate the power loss of PV modules from partial shading using Python coding. In-order to calculate the power loss of modules from partial shading, the current and voltage (IV) curves for individual solar photovoltaic cells should be calculated, by solving the single diode equation IV curve. Parameters of an available PV module are used. Standard Test Condition (STC) temperature and parameters are used in the calculations. Different Python libraries and packages are used and imported in this report. Brief introduction to the background of each library is introduced, steps of adding an external package to Python are also mentioned.
