Abstract
In Algeria, there are several photovoltaic water pumping system (PVWPS) which are situated in remote areas. Typical problems are detected as sizing of photovoltaic (PV) generator (over-sizing) and maintenance (underestimate) by many operators. Due to the high cost of setting up and maintaining a large number of data acquisition systems for the PVWPS, we have developed a real time expert system based on central microcomputer used as a micro-server, with a low cost. This paper presents a design of a universal data acquisition system for Algeria with available components and easily accessible with a central server. This data acquisition system analyses the performance of PVWPS. The systems hardware and software architectures and an application to test its performance are described.
