The testing includes a number of separate analyses. The first step is the acceptance test for the photovoltaic pumping system (PVP) which includes the PV generator, the mounting and tracking system (if part of the system), the controller and the water pump. These components are the “engine” of the SPIS, their performance is vital for the successful use of the irrigation system. |

Upon completion of the installation, the functionality and the performance of the system should be tested in the presence of the future user (producer). The testing includes a number of separate analyses. The first step is the acceptance test for the photovoltaic pumping system (PVP) which includes the PV generator, the mounting and tracking system (if part of the system), the controller and the water pump. These components are the “engine” of the SPIS, their performance is vital for the successful use of the irrigation system.
This acceptance test (also referred to as Site Acceptance Test, SAT) is the second level of material testing in view of quality management. Manufacturers of system components are obliged to run a Factory Acceptance Test (FAT) prior to releasing products to the supplier. Ideally, both levels of testing should be presented when evaluating an SPIS, but are not always readily available.
The different measurements should be carried-out within a short time interval under clear sky conditions. At least two ac-ceptance test runs are advisable, measuring at high irradiance (800 – 1,000 W/m2) and low irradiance levels (approx. 500 W/m2). The equipment for the test will be provided by the installer.
The results of the acceptance test should be compared with the design performance of the PV pumping system. The DESIGN – Pump Sizing Tool could be used to record the most important data and to compare it with the design values. The acceptance test protocol should be signed by the installer and the producer.
