Abstract
This paper presents the implementation of an integrated photovoltaic solar panel model which includes all the necessary parameters in order to simulate and analyze using Matlab/Simulink software. The integrated photovoltaic model is validated with Matlab/Simulink simulation for a commercially available 100W photovoltaic solar panel module. Using the commercial solar panel specifications, such as solar irradiation, panel temperature, etc. the integrated model solved with Matlab/Simulink returns an I-V and P-V performance characteristics under various conditions which enabled detailed analysis, assessment of parametric effect on the performance of the solar panel. According to the model simulation results for a commercial RNG-100D solar panel, it was found that panel performance was mostly affected by the variations of solar radiation/insolation, panel surface temperature, series resistance, shunt resistance and band gap energies of the semiconductor materials. The commercial solar panel simulation results show that a photovoltaic panel output power reduces as module temperature decreases. Taking the effect of sunlight irradiance and cell temperature into consideration, the output current and power characteristics of PV model are simulated and results can be optimized using the proposed model. The integrated model enables the dynamics of PV power system to be easily simulated, analyzed, and optimized.

Summary
Increasing world population and rapid expansion of industrialization have put an excessive strain on the fossil fuel based energy supply chain Fossil fuels such as gas, coal, oil and derivatives of oil account for over 80% of the world’s primary energy consumption and out of which 58% is consumed by the transportation sector and rest are used to meet the electrical energy demand [1,2,3]. The amount of solar energy can be harnessed from the entire surface of the earth is 1.22x1014 tons coal equivalent or 0.814x1014 tons of oil equivalent in one year. The solar energy is a dilute source of energy and its availability varies significantly with time and earth’s surface location. As PV cell exposed to the sunlight, photons with energy greater than the bandgap energy of the semiconductor are absorbed and create
