Abstract
In this study, the use of solar energy was analyzed, in conjunction with solar collectors and photovoltaics, for the preparation of domestic hot water in a single-family house. Both installations were considered for two countries, Poland and Finland. Irradiation, in both countries, was estimated by using the insolation calculator. Then flat plate and evacuated tube solar collectors were selected from two different companies. Next, their efficiencies, maximum heat outputs, SPBT (Simply Pay Back Time), and NPV (Net Present Value) were calculated. Eight different collectors were considered, and the most favorable option was selected from among them. In the next part of the thesis, the use of photovoltaics was analyzed. The power of installation and the number of panels were selected by the profitability calculator. The calculator presented three variants for which the power generated by photovoltaic panels was calculated. SPBT and NPV were also calculated. For the most favourable option, further analysis was carried out on the basis of external funding, for both countries. Additionally, a prosumer variant was analyzed for photovoltaics.
