Abstract
The main element of the work was the economic analysis resulting from the use of a photovoltaic installation cooperating with the installation of a heat pump in one of the single-family houses. It should be emphasized that the cooperation of photovoltaics and heat pumps, aimed at ensuring thermal comfort in the building and generating electricity, e.g. for the operation of a heat pump, it is one of the most economically advantageous technologies. In this work, the authors focused only on the assessment of the payback time of the sample photovoltaic installation, operating in Poland. Based on the analysis of the investment and operating costs of the installation, its profitability was demonstrated, while ensuring clean, practically maintenance-free energy production.
