The aim of the work on the title subject was to design, build and test a photovoltaic (PV) pump system in order to check the viability of the chosen concept. The principle of the pump system has been initiated by the Eindhoven University of Technology (TUE). Basically, the pump system consists of a PV-array, an electric motor and a slightly modified normal hand pump. The pump system contains no electronic equipment for the purpose of DC/DC matching, maximum power point tracking or power boosting. These features have been facilitated using a special piston valve: the TUE-matching valve. A PV piston pump equipped with the TUE matching valve has been realised at the Netherlands Energy Research Foundation (ECN). A short description of the pump system is given in chapter 2. For the purpose of the orientating field test the pump has been installed in a borehole with adjustable water table up to 50 meter below ground level on the ECN test station. The solar arrays have been simulated by a power supply with comparable characteristics as a solar array. With these facilities a number of tests have been performed. After some initial tests small modifications were made to the pump system. The modifications are briefly described in chapter 2. The procedures of testing and the data treatment are given in chapter 3. The results of two 'final' tests are also presented in chapter 3. Conclusions of these tests have been formulated in chapter 4. After the orientating field test the pump system will be tested in the laboratories of Genec in France. The results of the field test in Petten have been used for the parameter fitting of the dynamical model of the pump system, developed by TUE.
