The cultivation of negatively photoblastic plants requires, first of all, the provision of a constant supply of electricity, without which it is impossible to cyclically implement the process of watering the plants. Due to the large amounts of heat generated by plants during their growth, cyclic watering is not only necessary to provide water for their growth, but also to cool them down. Lack of power supply and failure to water within a certain period of time leads to overheating of the plants and their destruction, thus necessitating the disposal of the production batch. Ensuring stable power supply and energy security of the cultivation is possible with the use of an island PV plant, but only integrated with an appropriately sized energy storage. This paper presents the results of an analysis of the feasibility of using PV sources to ensure continuous cultivation of Mung bean sprouts. Determination of the energy demand of the sprout-growing plant was made based on the developed transient simulation model of the production line. The level of energy demand was determined for different production scenarios. The availability of solar energy at the location of the production line was analyzed and the size of the PV system integrated with energy storage was determined. For full-scale production, regardless of the period of the year in which it is carried out, the maximum energy demand was determined based on simulation studies at 36 kWh/day. For full-scale production, the size of the PV system should be at 96.5 kWp, and the capacity of the energy storage should provide weekly coverage of the production line and be about 252 kWh.
