Value of UK residential solar and storage compressed

The speaker installed a 4 kWp solar array and a 10 kWh battery system at his home in Oxford in 2023. In this talk, he shares what the data so far reveals about system performance, including operational modes, energy production and throughput, and the resulting cost savings and payback. He also uses historical data to explore how different time-varying tariffs might have affected operation and economics. Along the way, he connects these findings to our broader work on larger-scale grid storage, and discusses implications for battery ageing, grid carbon emissions, and wider policy and system issues.
