Profitability of a hybrid heating system for a single-family house in Poland based on a heat pump and photovoltaics

Abstract

The article presents an analysis of the profitability of an investment consisting of a heat pump and a photovoltaic installation located in Poland for an exemplary single-family house. The factors that have a significant impact on the profitability and payback time of such installations operating in a dual configuration are described. A simulation of profitability taking into account the legal regulations and support systems was presented. The considered case of profitability concerns a specific technical solution in which an 8 kW air / water pump was used. The pomp cooperates with a photovoltaic installation with a power of up to 10kW, operating in a discount system with an energy consumption factor of 0.8. For the purposes of this article, the DCF (discounted cash flow) method was used. Using this method, it is possible to calculate the market value of the investment with the assumed boundary criteria. A comparison of the economic efficiency of an investment can be presented using the IRR (internal rate of return) method.

Poland as the EU Leader in Terms of Photovoltaic Market Growth Dynamics—Behind the Scenes

“…Summarizing the research results, it was noticed that, surprisingly, as presented in the Photovoltaics in Poland section, the sudden and rapid increase in interest in individual investments in photovoltaics was not caused by climatic conditions [64,65] and the growing concern for the natural environment [66,67], but by numerous and very beneficial programs for individual recipients of co-financing investments in photovoltaic installations and favorable settlements regarding the surplus of solar energy produced [60]. An additional stimulus on the part of consumers concerned increasing energy prices-in Poland in 2020 alone electricity prices for individual consumers increased by over 10% [63]-as well as innovative and more and more effective technologies [50,[68][69][70].…”

“…Numerous studies of this phenomenon also show that climatic conditions [64,65] and growing environmental awareness [66,67], as well as innovative and increasingly effective technologies, are also important [50,68,69].…”

Analysis of the efficiency of a double-axis control system of a PV power plant in a solar tracking system

“…Increasing the efficiency of photovoltaic panels is one of the main problems being solved by engineers and scientists [2,[5][6][7][8]. Currently, the efficiency of such devices ranges from 15% to 25% and is very low compared to solar thermal collectors, whose efficiency ranges from 52% to 88% at T = 25°C and solar radiation intensity of 1000 W/m 2 [7,11,12].…”
