When the Rs were introduced into the Simulink model, the I-V curve of the simulated solar cell matched the real solar cell's I-V curve. To imitate the I-V curve behavior, a series resistor with a value of 0.0038 Ω was connected in series with 15 sub-cells.
The typical daily solar generation curve and load curve, as shown in figure 1, are derived from solar radiation and load supply data. Area 1 represents the user's power purchase, area 2 represents power exported to the grid, and area 3 represents solar generation used locally.
Results of the proposed solar cell model confirmed its ability to mimic the real solar cell I-V curve with a very small percentage of error, around 1%. Furthermore, FF revealed the highest percentage of error of 1.2% due to the additional wire losses in real solar cell.
Thus, the proposed solar cell model could be implemented to investigate degradations that have complex I-V curve behavior and improve the PV faults’ monitoring systems. Renewable energy sources, such as wind and solar energy, biomass, and hydropower, provide sustainable alternatives to fossil fuels for supplying the world's energy demands.
The PV characteristic curve, which is widely known as the I–V curve, is the representation of the electrical behavior describing a solar cell, PV module, PV panel, or an array under different ambient conditions, which are usually provided in a typical manufacturer’s datasheet.
The current-voltage (IV) curve of a solar cell, module, or string shows the relationship between the current (I) and voltage (V) that it produces under constant illumination conditions. A specialized equipment called an IV curve tester generates the curve. To ensure accurate results, the test is done when irradiance is more than 600W/m2.
