Photovoltaics in horticulture as an opportunity to reduce operating costs. A case study in Poland

Abstract

Abstract Fruit farms can become prosumers - producers of electricity for their own needs, without the possibility of selling overproduction. The subject of the study were the costs of electricity in fruit growing. The paper presents a research hypothesis that reads: Agriculture-Polish orcharding can contribute to an increase in the share of energy produced from renewable sources. The aim of the study was to determine the impact of installed photovoltaic panels on the cost of fruit-growing activities. The research methodology was based on a case study. An orchard farm producing apples and peaches on a total area of 33 ha was presented. The costs of fruit growing were developed and the share of electricity consumption costs was indicated in them. Studies have shown that a return on investment in photovoltaic panels is possible after about 8 years. Energy costs account for around 6% of the cost of an orchard. Installing photovoltaic panels on the roofs of cold stores will reduce these costs by half. The main conclusion of the study is that the costs of electricity consumption can be reduced in Poland as a result of the use of fotovoltaic installations, provided that you receive financial support from the state or other institutions, e.g. in the form of subsidies or exemption from agricultural tax.
