Hybrid solar-fuel cell combined heat and power systems for residential applications: Energy and exergy analyses

► A residential solar PV-hydrogen CHP system is developed. ► The residential CHP system is assessed based on energy and exergy. ► The PV delivers its max. power to a house with 3.35 kW max. power demand. ► 0.792 kg hydrogen is generated with the surplus electricity of the PV. ► Maximum total energy and exergy efficiencies are 55.7% and 49%, respectively.
