Technical and economic analysis of a residential heat pump with photovoltaic solar panels in self-consumption for space heating, cooling and DHW.

Author(s) : JORQUERA FERRAT P., MONDOT M.

Summary

Two different thermodynamic systems for space heating, cooling, and domestic hot water production coupled to photovoltaic panels have been studied. The aim is to assess the PV electricity self-consumption variation with the heat storage volume and the applied control strategy. Each system has been studied using a 1D unsteady state modelisation software to simulate its performance in a house complying with the French building code (RT2012) having a DHW demand according to ErP’s load profile M and with Paris weather data. The main parameters studied are the electricity consumption of the thermodynamic system, the seasonal performance factor (SPF), the self-consumption ratio, the self-production ratio, the coverage ratio and the Return on Investment. The results show that the seasonal efficiency can be doubled thanks to the optimization of the PV electricity self-consumption, which results in a return on investment lower than 15 years.
