Abstract
Photovoltaic cells are one of the best alternatives to fossil fuels for electricity generation. These cells are affected by the surrounding atmosphere. The ambient temperature and the solar radiation intensity are the most important climatic factors affecting the photovoltaic power. Any change, even a small fraction of these factors, directly changes the current and voltage of the solar panel, leading to changes in the I-V and P-V curves. In these curves, there is a point called MMPT representing the maximum power produced by the photovoltaic cell.
In this study, one of the main methods of MMPT was studied to reach the maximum power point (MPP) of the PV panel. The studied method is Incremental Conductance (INC). This method was subjected to the conditions of temperature and solar radiation for the city of Baghdad, Iraq for the purpose of examining the conditions and response time, and was investigated the flexibility of the response of this method when solar radiation in the range of 300 W / m to 1000 watt / m 2 while changing the temperature in the range of 0°C to 70 °C. For the studied method INC, the generated power curve reached maximum value without oscillation, and the manganese stabilized after 0.15 seconds. The data used in the model is the data of the city of Baghdad – Iraq. The results of the study indicate that the method INC provides better and faster stability.
