Economic and Technical Aspects of a Hybrid Single-Family House Heating Based on Photovoltaic and Heat Pump Installation

The paper presents an analysis of a hybrid investment containing a photovoltaic installation and heat pump for an exemplary single-family house. Mechanisms supporting such installations in dual configuration are presented on the background of their profitability in Poland. In the process of estimating investment profitability, a number of factors having a significant impact on the final effect were taken into account. The authors presented a simulation of the profitability of a dual investment, taking into account the most important investment elements. The analysis was carried out using the DCF (discounted cash flow) method, which allows calculating the market value of investments at the assumed boundary criteria. The comparison of economic efficiency of such investments compared to investments only in the heat pump and investments in alternative capital management in treasury bonds was presented using the IRR (internal rate of return) method.
