Experimental Evaluation of a Photovoltaic System to Feed an AC Load

摘要

The applications of renewable energy systems have become very interesting in various sectors nowadays. One of the most well-known applications is a photovoltaic system. However, the outcomes power generated by the photovoltaic conversion hinges on climatic condition at the site location. In this work, an experimental examination was done to evaluate the performance of photovoltaic system; installation was at the LAGE laboratory (Ouargla University). The system contains two polycrystalline photovoltaic modules, power management unit, a lighting lamp and a data acquisition unit, the solar modules generate a direct current to charge the electric accumulators via solar regulation unit. The power management extension, including a solar controller, a DC-AC inverter, a DC-DC converter (to supply AC and DC loads) and a battery bank. The aim of these experimental tests is to supply such a lamp with clean electricity without using the electrical network, after that to evaluate photovoltaic system components efficiency.
