| Popis: | Since the first installations of solar systems, PV pumping systems have taken a large part in solar energy projects and nowadays they belong to the most significant applications of photovoltaic energy. With the increased use of the PV water pumping systems, sizing and selecting suitable design is essential in order to achieve the most reliable and economic operation for this type of systems. On a real well of 25 m head in desert and semi-arid climate in Sebseb site, Ghardaia, Algeria, a typical PV pumping system for irrigation purpose is installed in order to evaluate its performance under outdoor conditions. Therefore, three PV array configurations are considered to supply a novel version of centrifugal solar pump PS2 C-SJC 12 with a storage tank. The pumped water is used to irrigate 3 hectares of agricultural land. Oversized PV array increases its output power at weak solar irradiance. However, too much oversize will negatively affect the economic reliability. With respect to the wide normal operating range of centrifugal pump, three oversized PV configurations by 4%, 46% and 78% are examined. The experimental results show that PV pumping system can successfully start at low solar radiation 86.21 W/m2 and the optimum performances are obtained with the oversizing of 46%. |
