Description:

Renewable energy sources are increasingly common in Poland, and a growing number of single-family houses are now equipped with such systems. The article presents the study of the performance of the heat pump and the photovoltaic system installed in a house in the Swietokrzyskie Province near the city of Kielce. The data related to thermal and electrical energy generation throughout three years has been analysed with a focus on the advantages offered by such systems in the climate conditions of Central Poland. It turned out that 2022 was the best year for electricity production because it exceeded the value of 8000 kWh, and in the winter period from November to February, energy production balances at 200-300 kWh, which proves the high efficiency of panels for electricity production even in unfavourable climatic conditions. The heat pump generates the smallest energy production to heat the house in the summer, while in the winter, this production increases intensively due to the heating season in Poland. These are values from 1500 kWh to values above 3000 kWh. Similarly, in the case of domestic hot water, these values are higher in winter than in summer. Additionally, the work includes electricity consumption before and after the installation of renewable energy sources. Simplified economic analysis has also been presented in the paper. The simple payback period is estimated at approximately 9 years.
