This paper presents two mathematical motor-pump models for photovoltaic (PV) applications. These models will allow us to obtain the operating point with the PV array and the flow rate of the pumped water. The modelled motor-pump characteristics are current–voltage and flow–voltage. The...

The aim of this work is to analyse the performance of different photovoltaic water pumping systems. The Typical Meteorological Year (TMY) data from four distinct Algerian climatic sites are used: Algiers, Bechar, Oran and Tamanrasset. The study has been carried out for three different profiles,...

The aim of this article is to describe how closely PV grid-connected inverters (of around 5kW) operate at the actual maximum power point. These inverters could be installed at any low voltage, PV grid-connected systems. To carry this study out, twelve 50Hz single-phase inverters were selected...

At present, photovoltaic grid-connected systems (PVGCS) are experiencing a formidable market growth. This is mainly due to a continuous downward trend in PV cost together with some government support programmes launched by many developed countries. However, government bodies and prospective...

In the photovoltaic field, manufacturers provide ratings for PV modules for conditions referred to as standard test conditions (STC). However, these conditions rarely occur outdoors, so the usefulness and applicability of the indoors' characterisation in standard test conditions of PV modules...

An optimal compromise between energy efficiency and aesthetics for PV in the built environment sometimes requires to divide the PV field into sections with different orientation and tile each, which are connected to a single inverter. From the experience and data collected through a year of...
