| Thermal conversion of solar energy is often used for the preparation of domestic hot water due to possible reduction of fossil fuels consumption. According to Eurostat data, the total surface of installed solar collectors in the European Union in 2017 exceeded the amount of 52 million. However, application of solar collectors in multifamily buildings or service facilities raises many concerns mainly related to economic aspects including investment, maintenance and operation costs. This paper presents the economic analysis of several variants of system designed to domestic hot water preparation in hotel and catering building, located in the Eastern Poland. The analysis includes a domestic hot water (DHW) installation, consisting of hot water and circulation, and three different sources of energy applied for hot water preparation: solid fuel boiler, gas boiler and gas boiler supported by solar collectors. The performed economic analysis was based on popular indicators of investment cost efficiency: Dynamic Generation Cost (DGC), Net Present Value (NPV) and Benefit-Cost Rate (BCR). The required input data for determination of costs efficiency indicators were based on preliminary investment costs estimation as well as assumed operation and maintenance costs. Additionally, energy and economic benefits of solar installation were estimated by GetSolar software. |
