Abstract


A major factor of future green energy systems for power stability is performance analysis of renewable resources. In this paper, the authors aim presenting details on the effect on commercial PV in Doha weather and particular soiling of panels (dust settlement). The authors designed an in-house system featuring a wireless remote monitoring thus allowing access of recorded data ubiquitously from anywhere on the web. A novel electronic load based on a DC-DC converter, that is controlled by a micro-controller is used to log PV currents and voltages, allowing hence plotting P-V and I-V curves at any time for analysis and interpretation. Two XBee Pro transceivers were used to transfer the measured data wirelessly from the rooftop sensors and electronics modules to a LABVIEW based monitoring station. Nevertheless, the system measures and save climatic and environmental conditions such as ambient and panel temperatures, relative humidity, solar irradiance, dust and wind speed. In addition, the work aims at providing empirical results of PV panels to help solar PV installers in predicting the performance and energy yield for a certain PV technology under different climatic conditions. The dust effect on PV module was analysed by exposing the module to dust and airborne particles on rooftop. It is worth to mention that the maximum power output from Poly-crystalline panels deteriorated by around 30% for a dust exposure of 5 months. Furthermore, the study suggests operating solar PV plants in Doha from 09:00 am to 01:00 pm to optimize production.
