Operational experience of a residential photovoltaic hybrid system
This paper reports on the operational experience acquired with a photovoltaic (PV) hybrid system installed as a line extension alternative at a residence located in northern New York State. The system includes an 850 W PV array, 25 kWh worth of battery storage, and a 3 kW propane generator. The paper features a detailed analysis of the energy flows through the system and quantifies all losses caused by battery storage round-trip, rectifier and inverter conversions, and non-optimum operation of the generator and of the PV array. The paper also analyzes the evolution of end-use electricity consumption since the installation of the PV hybrid system.
