Abstract:Due to the variation of solar irradiance, temperature and shading conditions, the power generated by a photovoltaic (PV) module and hence the power delivered to the load changes drastically, which imposes the need for analysis of a complete PV system to get the maximum power under these natural variable conditions. In this paper, a complete off-grid PV module based power generation system has been designed and simulated using MATLAB/Simulink and performance has been scrutinized using the value of standard sola… Show more

Solar energy is among the source of energy that is reliable, available and non-harmful to the society. The output of solar photovoltaic system can be improved by means of solar tracking system either mechanically or electrically. The modules of solar PV system are oriented so as to harness maximum solar irradiance from the sunlight. The performance of solar modules depends on the temperature of the solar modules. This present work deals with simulation of a solar PV module using Scilab Xcos software at different setups and operating conditions to give I-V and P-V curves. The results of the simulations show that a PV array that were modeled and simulated for variable solar irradiance maximum of one sun (700W/m2 to 1000W/m2) and constant temperature 250C, this increase in irradiance therefore lead to increase in current with the voltage remained relatively constant throughout the irradiance range.

“…The goal of this study is to design and develop simulation of solar panels connected in series integrated with a boost converter and MPPT algorithm taking into account the effects of partial shading. In the study [4], MATLAB/Simulink was used to design and simulate a complete off-grid PV module based power generation system. The value of standard solar irradiance about 1 KW/m 2 was used for Bangladesh.…”
Section: Introduction and Literature Reviewmentioning
Experimental tests were performed to study the effects of shading for different string inside the photovoltaic (PV) panels, power equipped with different number of diodes from the same manufacturer as of solar panel. The IV curve for all cases were recorded to see how the bypass diodes will reduce the effects of shading .The case for 3 by pass diode show the best performance of solar PV module under shading phenomena.
“…In the study [7], the behavior of a photovoltaic device (cell or module) under partial shading conditions were reviewed and analyzed by using MATLAB. In the study [8], MATLAB/Simulink was used to design and simulate a complete off-grid PV module based power generation system. The value of standard solar irradiance about 1 kW/m 2 was used for Bangladesh.…”
<p>Experimental and simulation work were performed to study the effects of shading for different strings inside photovoltaic (PV) panels under real outdoor environmental climate conditions for Sharjah, United Arab Emirates. The electrical characteristics of PV panel were measured by using the PV analyzer, while the simulations were performed by MATLAB. The effect of full cell shading were studied experimentally for each configuration of two or four bypass diodes and verified by theoretical modeling. The I-V and P-V curves for all cases were recorded to investigate the effect of bypass diodes in reducing shading losses under similar environmental conditions. Compared to design with fewer bypass diodes, inserting more bypass diodes (four diodes in our work) contributed to higher yield in performance of solar PV panels undergoing shading while taking in to account the cost of energy production. Compared to the case of two bypass diodes, applying four diodes can recover up to ~31% of non-shaded maximum power under different cell shading conditions. </p>
