A novel analytical model for determining the maximum power point of thin film photovoltaic module

Abstract: Achieving the maximum power output from photovoltaic (PV) modules is indispensable for the operation of grid‐connected PV power systems under varied atmospheric conditions. In recent years, the study of PV energy for different applications has attracted more and more attention because solar energy is clean and renewable. We propose an efficient direct‐prediction method to enhance the utilization efficiency of thin film PV modules by tackling the problem of tracking time and overcoming the difficulty of calcula… Show more

“…, , and of the proposed MPDE method, the local MPP of the PV system can be estimated. As shown in Figure (a,b), only one MPP exists in the P–V curve of the PV system under a uniform irradiation intensity of 1000 W/m 2 and a temperature of 25 °C with various shading strengths, that is, j = 1, and a given temperature . We can directly calculate the sets of the voltage proportional index ( m Vj ) and current proportional index ( m Ij ) at the MPP of the local PV module group using Eqns.…”

“…An irradiation condition and a surface temperature of the PV cells/modules are related essentially to the characteristic and the performance of the PV cells/modules. The performance of PV cells/modules is found to be affected by environmental conditions, such as irradiation intensity and temperature , by examining the field‐testing data and experimental results. The changes in temperature mainly affect the PV output voltage, while irradiation intensity changes mainly influence the PV output current .…”
