Abstract
This paper analyses the impact of using battery storage in solar PV homes. It uses actual PV generation data and smart meter data from a case study of a house in Geelong, Australia, to study this. As the adoption of intermittent solar photovoltaic (PV) systems grows, storage capacity, such as batteries, is required to match unpredictable generation with uncertain demand. The results show that applying a 10 kWh battery to a 10 kW solar PV system can reduce annual imported energy by 95%. In order to make the house grid independent, a 20 kWh battery is required with a payback period of 25 years. In addition, PV self-consumption and PV self-sufficiency rise as the battery capacity increases, but this trend is limited by constrained PV generation in winter. This study demonstrates the feasibility of applying battery storage in solar PV homes, but the characteristics of PV generation and house power demand need to be considered to determine the best combination of PV and battery system size.
