A methodology for the construction of efficient PLC based low-power photovoltaic generation plants

The research of the operation of low-power photovoltaic generation plants used for self-contained electric power supply in Siberian climatic
conditions is performed in this paper. It provides an analysis of the operation of individual units of an automated control system, and gives
recommendations for the selection of hardware components. The article describes the operational principles, developed based on functional
modules of the programmable logic controller, ensuring maximum possible use of solar energy in this continuous power supply system. The results
of plant operation have been obtained, in the form of a power counter log, as well as data on the volume of solar energy produced in both overcast
and in sunny weather, throughout the observation period. The article provides visual illustration of generated energy, which could be used to assess
the efficiency and economic viability of the low-power photovoltaic plant. Authors would like to point out that examples of the proposed
methodology for the construction of self-contained power supply systems can be found in existing industrial facilities, on which further scientific
research can be based.
