Summary: David installed a 4 kWp solar array and a 10 kWh battery system at his home in Oxford in 2023. In this talk, David will share what the data so far reveal about system performance, including operational modes, energy production and throughput, and the resulting cost savings and payback. He will also use historical data to explore how different time-varying tariffs might have affected operation and economics. Along the way, David will connect these findings to our broader work on larger-scale grid storage, and discuss implications for battery ageing, grid carbon emissions, and wider policy and system issues.
Speaker: David Howey is Professor of Engineering Science at the University of Oxford, specialising in modelling, control and diagnostics of battery energy storage systems. He leads a research group working on advanced instrumentation, probabilistic machine learning and electrochemical modelling to improve battery performance, lifetime and sustainability, with applications in electric vehicles, grid storage and off-grid solar systems. He has co-authored 150+ peer-reviewed papers, holds several patents, and works closely with industry and international research partners. David is co-founder of the Oxford spin-out Brill Power, co-organiser of the award-winning Oxford Battery Modelling Symposium, and was recently elected an IEEE Fellow.
