Examining the Performances of a Low Power Photovoltaic Installation

Abstract

Low power photovoltaic installations must ensure the necessary energy level requirements of the installation’s beneficiary. At the same time, it must be conform to the legal regulations and norms. When a photovoltaic installation is to be delivered into the power supply network, its operating parameters must be closely monitored. In this work we present the results of our monitoring of a low power photovoltaic installation. Upon examination of the voltage variations, of the currents, of the voltage and current harmonics, we conclude that the installation we studied does indeed fulfill the necessary requirements for connecting to the national power grid. Examining the energy levels consumed by the beneficiary, we find that the photovoltaic installation cannot continuously ensure the required energy levels, which recommends the acquisition of an additional photovoltaic installation.
