ABSTRACT
This paper discusses the idea of combining a photovoltaic system with a heating film system to heat residential buildings. The analysis was performed for a newly built single-family house in Warsaw or its vicinity. The authors have selected the size of the photovoltaic installation, calculated the costs incurred by the user for the installation of a hybrid system, which were additionally compared to the cost of installing a gas installation (gas boiler) used for heating the building.
The calculations were made for a single-family house with a usable area of 120 m2, the demand for utility energy for heating purposes in the newly built house was in the range of 10–50 kWh/m2/year.
Based on the adopted parameters, the authors evaluated the economic efficiency of both investments (solutions) determining their net present values (NPV). The analysis takes the energy needed only for heating purposes into account.
NPV for a heating system with a gas boiler with an investment outlay EUR 8,000 for buildings purchased for utility energy in the amount of 20 kWh/m2/year and the price for natural gas EUR 0.04 /kWh will be EUR –10,500 (for 15 years, discount rate r = 3%). For the same thermal needs
(energy required) of the building, NPV for heating films + photovoltaic (HF + PV) will amount to – EUR 8,100. Comparing the variants will get a EUR 2,400 higher NPV for HF + PV. With a utility energy demand for heating purpose of 50 kWh/m2/year and gas heating installation investment cost of EUR 7,000, the NPV for both variants will be equal for natural gas price = EUR 0.035/kWh.

Folie grzewcze jako element współpracy fotowoltaiki z systemem grzewczym w domach jednorodzinnych

W niniejszym artykule zaprezentowano możliwości ogrzewania budynku mieszkalnego z zastosowaniem hybrydowego współdziałania systemu fotowoltaiki wraz z systemem folii grzewczych. Analizę przeprowadzono dla nowo wybudowanego domu jednorodzinnego w okolicach Warszawy. Autorzy dokonali wyboru wielkości instalacji fotowoltaicznej, obliczyli koszty poniesione przez użytkownika w celu montażu systemu hybrydowego, które dodatkowo porównali do kosztów montażu instalacji gazowej (kocioł gazowy) służącej do ogrzewania niniejszego budynku.
Obliczenia wykonano dla domu jednorodzinnego o powierzchni użytkowej 120 m2, zapotrzebowanie na energię użytkową do celów grzewczych w zakresie 10–50 kWh/m2/rok.
Na podstawie przyjętych parametrów autorzy ocenili efektywność ekonomiczną obu inwestycji (rozwiązań: fotowoltaika + folie grzewcze, ogrzewanie gazowe) wyznaczając ich wartości bieżące netto (NPV). W analizie uwzględniono tylko energię potrzebną na cele grzewcze.
NPV dla instalacji grzewczej z kotłem gazowym o nakładzie inwestycyjnym 8000 EUR dla budynku o zapotrzebowaniu na energię użytkową w ilości 20 kWh/m2/rok i cenie za gaz ziemny 0,04 EUR/kWh wyniesie –10 500 EUR (na 15 lat, stopa dyskonta r = 3%). Dla analogicznych potrzeb cieplnych budynku, NPV dla folii grzewczych + fotowoltaika (HF + PV) wyniesie –8100 EUR. Porównując warianty, wyższe NPV o 2400 EUR zostanie osiągnięte dla wariantu HF + PV. W przypadku zapotrzebowania na energię użytkową na potrzeby grzewcze na poziomie 50 kWh/m2/rok, przy nakładach inwestycyjnych 7000 EUR. wartości NPV dla obu wariantów będą równe przy cenie gazu ziemnego 0,035 EUR/kWh.
