The article aims to present projected cost and profitability of investment in photovoltaic installations on an agritourism farm. Special attention is drawn to economic efficiency of a system of photovoltaic modules installed on an agritourism farm hosting a four-member tourist group and using a photovoltaic system having a capacity of 5 kWp. It has also been assumed that the whole amount of electricity produced is used on the agritourism farm. The analysis results have taken into consideration the assumption estimating the use of energy at the level of about 5,000 kWh per year. The annual energy cost estimation is PLN 2,750 (5,000 kWh x PLN 0.55).
