 *PV water pumping works best with low pressure drip irrigation systems.
 *The direct connection of the solar pump to the irrigation system leads to a dynamic and varying hydraulic load, which makes planning more complex.
-*Varying hydraulic loads can be mitigated by are (a) using automatic valves, (b) adapting irrigation field size (c) and solar tracking.

 Figure 2 shows another, more common, configuration where water is pumped from the ground and stored in an elevated reservoir. The water goes through the irrigation head, which can be equipped with volumetric valves, and/or a fertigation system. Nevertheless the producer is forced to divide the field into small sections to allow a relatively controlled distribution of water across the field. This SPIS configuration requires relatively little maintenance as the panels and the pump are fixed.

 Figure 1 shows an SPIS configuration where one saves on the costs for the reservoir but spends on the tracking systems. The tracking system enables a relatively stable pump dis-charge which is important, because there is no reservoir to buffer the amount of water going to the field. The water can further be controlled by the valves and by splitting up of the drip irrigation system in sections.
