Design and performance evaluation of a photovoltaic grid-connected system in hot weather conditions
چکیده انگلیسی

A pilot photovoltaic (PV) grid-connected system rated at 36 kWp has been designed and installed at the 0.4 kV level of the Abu Dhabi distribution network. The performance of the system under the actual weather conditions has been evaluated in terms of power and energy production, conversion efficiency, consistency of voltage and frequency, along with the impact of ambient temperature. Additionally, the influence of accumulated dust deposition on the production of the PV array has been evaluated. The evaluation showed consistent operation of the system with a moderate conversion efficiency even with the high ambient temperatures at the site. However, the dust deposition on the glazing of PV modules was found to seriously degrade the performance of the PV system.The outcome of this work is deemed important in assisting accurate PV system design, and also in scheduling suitable cleaning cycles for the PV strings. In this regard, cleaning the strings on a monthly basis was found to give reasonable results.
