These conditions are kept same in all over the world and performed in irradiance of 1000 W/m 2 under a temperature of 25 °C in air mass of 1.5 (Abdullahi et al., 2017). Simulation of the solar PV model executes the I–V and P–V characteristics curves.
An empirical general photovoltaic devices model was studied in , and a method called APTIV, which fits the I–V curve in two different zones was used to extract the solar cell physical parameters . Accuracy, however, focuses only on the three characteristic points, rather than the complete characteristic curves.

A PV model can be simply described as a mathematical representation of the electrical behavior of PV panels for simulating and predicting the performance of PV panels in commercial software environments such as MATLAB/SIMULINK, PSIM, etc. [23, 24, 25, 26].
Simulation of the solar PV model executes the I–V and P–V characteristics curves. Generally a good agreement was observed between various performance parameters results of reference model and simulated PV model at STC as illustrated in Table 3. The relative error for all the parameters of solar PV model is comprised between 0 to 1.65%.
