| The objective of this study was to assess whether precision photovoltaic irrigation represents a sustainable alternative to traditional systems, where the energy and environmental performances were firstly evaluated through energy and carbon payback times (EPBT and CPBT). The study involved five Photovoltaic Irrigation Systems (PVIS), ranging from 40 to 360 kWp, installed in Spain, Portugal, Morocco and Italy. The results show an average EPBT of 3.3 years and CPBT of 6.3 years, with an energy return on energy invested (EROI) of 9.0. Additionally, the PVIS were able to achieve low emission rates with an average of 77.4 g CO2e per kWh produced. The energy and environmental performance of the PVIS are closely influenced by weather conditions, irrigation requirements and water availability. Moreover, the implementation of precision PVIS allowed improving the irrigation practices, avoiding the exploitation of natural resources and the emissions of large amounts of GHG to the environment. | |
