Application of Photovoltaic Systems for Power Supply of Heat Pumps

Electricity consumption worldwide is increasing day by day, and as we all aim to reduce the harmful impact on the environment due to increased electricity production, humanity is turning to electricity generation from renewable energy sources. In 2021, a total of 315 GW of new renewable energy sources were installed. The Republic of Croatia recognized the importance of renewable energy sources in due time, and the share of renewable energy sources in the final electricity consumption is above the European Union average. This paper aims to demonstrate the profitability of photovoltaic systems for powering heat pumps, specifically replacing gas heating with an air-water heat pump powered by a photovoltaic system.
