The economically optimal designs provided by the model are not achieved for a completely full irrigation of the crop but rather for deficit irrigation. In this way, we propose a new approach to PV irrigation systems design and management that we call PV opportunity irrigation (PVOI). PVOI makes use of the ability of many crops to undergo some water stress without experiencing a significant yield loss in order to reduce the size of the PV irrigation system. The operational strategy in the PVOI approach is to irrigate as long as enough power is supplied by the PV array. Unlike any other conventional design method available in literature, the total amount of water applied to the crop depends on the energy provided by the PV array rather than on a strict fulfillment of the pre-established crop water irrigation requirements. The application of the PVOI approach implies not only a reduction in the investment costs of the system but also some water savings, which is very important in areas with water scarcity.
