Solar photovoltaic (PV) systems find a large market in the developing countries in Asia, Middle East and Africa. Most of these areas are characterized by solar energy availability over a large part of the year. This paper presents the results of the experiment carried out in Armenia on a 420 Wp PV water pumping system, under two operational conditions: fixed and tracking modes of the PV modules. The overall performances of pumping system were analyzed and evaluated during the monitoring period. Results show that, for the climate of Yerevan city, the pumped water volume of the tracking PV modules is 1.2 - 1.3 times greater than the value obtained with the fixed PV modules. In September 2007, based on the results achieved in the territory of Viasphere Technopark Co. (Yerevan), 3.1 kWp tracking PV water pumping demonstration system for micro irrigation of the Technopark garden (0.2 hectare) has been developed, constructed and setup. At present, with the help of specially developed Data Acquisition of program, seasonal testing of demonstration system for evaluating and analyzing performance of PV system, according to the overall effect of environment conditions on their operation characteristics, is in process.
