Low-power Photovoltaic Installation Behavior Analysis

There is an increasing trend in employing re-usable energy sources, both by industrial and private household consumers. In this work, we present measurements performed on a 40 kW photovoltaic installation mounted on a manufacturing hall. Our measurements indicate the level to which the photovoltaic installation covers the necessary electric power requirements as well as the quality specifications for the provided electrical energy. By raising the P-Q diagram we can analyze the domain where the operating point of the installation may be found. Furthermore, we give indications on how to ensure the power autonomy on the consumer’s side, by the use of accumulators that store electric power during low-sun periods.
