The influence of climatic conditions on the efficiency of the photovoltaic parallel consumer supply system

This paper explores the diagram of a parallel DC consumer supply from a photovoltaic module and a centralized grid. It considers environmental factors affecting the maximum power of the photovoltaic module and the overall efficiency of the system, as well as establishes a connection between the base voltage of the parallel power supply circuit and the efficiency of power take-off from the photovoltaic module. The calculation of system parameters for a typical household module is presented. The results show that when using the proposed calculation method, the power reduction in winter will be no more than 6 %, and in summer - no more than 7 %, relative to the maximum power of the photovoltaic module in the respective seasons.
