“…As a consequence, for accurate modelling of a PV module, the values of all five parameters are evaluated at different environmental conditions [23]. The open circuit voltage of the PV panel is decreased when the panel temperature is increased and vice versa [24]. The thermal voltage is indirectly proportional to open circuit voltage and this concept is used to form the new equation (32).…”

Abstract:The objective of this paper is to estimate the values of five parameters ( A , Rse , R sh , ILG , and Isat) of a PV module more accurately and to extract the maximum power point (MPP) accurately under varying environmental conditions. Suitable new equations are proposed, by which the values of the series and shunt resistances are initialized in order to obtain good convergence speed in the Gauss-Seidel method. In this work, two new equations are proposed to find the ideality factor and shunt resistance and to obtain accurate MPP of the PV model under varying environmental conditions. The proposed PV model is validated at standard test conditions and under varying environmental conditions. Current-voltage and power-voltage characteristics of different PV modules are simulated using MATLAB. Accuracy of the proposed model is validated by comparing with the results of an adaptive neuro-fuzzy inference system and experimental data taken under varying environmental conditions.

This paper describes the design, development and performance of a locally developed data acquisition system for solar PV module with variable load. The system can automatically change the operating point of a PV module and acquire the output voltage and load current into computer and then analyze. To change the operating point, a variable load has been developed by IRF250 MOSFETs. The current drawn by the load from the PV module is controlled by a staircase voltage, which is developed by a counter and a DAC. The count value of the counter and hence the voltage level of the staircase is changed by an Arduino-based controlling unit. To get the short-circuit current, the PV module is connected in series with a high ampere power supply and the voltage across the PV module is conditioned by a difference amplifier and fed to an ADC channel of the controlling unit. The output current of the PV module has been sensed by a Hall sensor, ACS712, and read by another ADC channel. To make the whole system automatic, a program has been developed using Arduino IDE and loaded in the Arduino board. With the help of this program, the system can measure the current and voltage of the PV module and send to a PC. This acquired data is processed by software and the performance of the PV module is obtained. The system has been developed in laboratory and its performance has been studied. Although, there are some fluctuations in the acquired data but with filtration satisfactory performance is obtained. This instrument can be used for PV module testing purpose. Dhaka Univ. J.

“…Without having enough information regarding the panels behavior one cannot effectively size and design the photovoltaic systems. Intensive literature review reveals that in order to understand the performance of solar cells under variable light intensity and temperature, researchers have utilized solar simulators, and/or filtered lamp intensities in the laboratories (indoor condition) [7][8][9][10][11][12][13]. However, little attention has been paid on the practical investigation of inorganic solar panels under different sunlight intensities and temperatures in outdoor situations.…”

Abstract:In this work the impact of sunlight intensity and ambient temperature on the inorganic solar panels in winter climate (22 November 2015) at Sarwchawa, Kurdistan Region, Iraq was carried out. A maximum intensity of sunlight (106.25 klux) was reached at 12:00 PM. However, beyond 12:00 PM the intensity showed a non-monotonic change behavior. This was ascribed to the change of sun position, its orientation and the direction at which the surface of the panel is illuminated. Results showed that the increase of sunlight intensity has made I sc to increase, while that of the V oc remains relatively unchanged. The reason why I sc is more affected by the sunlight intensity was understood from the fact that charge carriers acquire enough kinetic energy to move towards their corresponding electrodes before they relapse or recombine together, while as V oc is mostly correlated to the energy gap. There was a trivial decrement of efficiency with the increase of temperature. This was where the FF showed a reverse trend of increment with the increase of temperature. Noteworthy, at the points where the fill factor was decreased the efficiency was increased and vice versa.
