Impact of Environmental Conditions on the Performance of a 300 kWp Solar PV Plant in Djibouti

Résumé

The impact of environmental conditions (temperature, dust) on the performance of a 300 kWp PV power plant operating in Djibouti since 2012 is presented in this work. The final yield (Yf) ranges from 3.5 h/d and 5.3 h/d giving and annual final yield of 4.5 h/d. The performance ratio (PR) ranges between 71 and 90%. An observation based on the evolution of the PR with ambient temperature increases showed that an increase of the temperature of 1°C induce a decrease of 1% of the PR. The dust accumulation has a real impact on the PV performance. In order to evaluate this impact, we observed the PR of PV array before and after a rainfall and it was found an improve of PR of 7.4%. In addition, we present in this work a TRNSYS model based on a model from standard library to predict the array performance. A comparison between model and measurements provide a gap of 2.36 kW. Also it was found that the predicted module temperature underestimates the measured temperature at low irradiance (less than 250 W/m2) and overestimates for high irradiance.
